Toshiba Laptops Disassembly Manuals

The following laptop step-by-step disassembly manuals I have created myself. You can use them if you have a Toshiba laptop and want to repair or upgrade it yourself. You shouldn’t disassemble your laptop if you have no experience with computers because you can easily damage it. Also, you shouldn’t open it if the laptop is still under warranty. I’m still developing new laptop teardown guides and my goal is to add new guides every week. If you do not see a manual for your model, most likely I will add it later. Stay tuned.

Why laptop runs hot and turns off or freezes?

My laptop runs very hot and eventually turns off or freezes – this is one of the most common complaints I have been receiving from my customer for many years. Why it’s happening? Is there an easy fix for that?
Most likely this problem is heat related. Take a look at the following picture.

Any laptop has a cooling module which consists of heatsink and cooling fan. When laptop is working, the processor (CPU) heats up and because of that the heatsink is getting hot too. At some temperature level, the fan kicks in and cools down the heatsink.
The problem starts when the laptop cooling module collects too much dust inside. Usually dust collects between the fan and heatsink. Dust clogs the heatsink and kills normal airflow inside the cooling module. Eventually, the processor gets very hot and the laptop turns off unexpectedly or freezes. This problem can be fixed by cleaning the laptop cooling module.
Cleaning laptop cooling module.
Some laptops give you an easy access to the heatsink and fan. In laptops like that you can access the cooling module through the bottom cover.

In my example I had to remove the cooling module. Otherwise, I wouldn’t be able to remove the fan and access the heatsink. In some laptops you can remove the fan without separating the heatsink from the CPU.
After I removed the fan, I found a thick layer of dust inside the heatsink. Cleaning the heatsink should fix any heat related problems.

Apply thermal paste on the processor.
If thermal paste on the processor dried out, you should replace it with fresh thermal paste.

Remove old thermal paste from the processor and heatsink using alcohol swab.
WARNING: In some laptops the heatsink also covers the graphics chip. The part of the heatsink which covers the graphics chip might have thermal pad on it instead of regular thermal paste. Do not replace thermal pad with thermal paste! Do not apply thermal paste on the thermal pad! Just leave thermal pad alone and apply thermal paste only on the processor.
I usually use Shin-Etsu thermal paste which is relatively cheap and performs well.

After applying new thermal paste, install the heatsink and fan back into the laptop. Do not forget to connect the fan cable to the motherboard!
What if cooling module cannot be accessed easily?
In some laptops the cooling module is buried deep inside the case and cannot be easily accessed and removed. In order to remove the cooling module it’s necessary to disassemble the whole laptop but it’s only for experienced users.
In laptops like that you can use the following technique:

Buy a can of computer compressed air.
1. Blow air into the fan grill on the bottom of the laptop.
2. Blow air into the grill on the side of the laptop.
Switch direction a few times until all dust is gone. Most likely this quick cleaning will fix your laptop overheating problem.

How to fix laptop motherboard with failed NVIDIA graphics chip

In this post I explain how you can fix a laptop motherboard with failed NVIDIA graphics chip. This repair might apply to some HP/Compaq laptops and probably some other laptop brands. If this repair works for your laptop, please mention the brand and model number in comments after the post. This will help other readers with similar laptops.
This method should work for the following models: HP Pavilion dv2000, Pavilion dv6000, Pavilion dv9000, Compaq Presario v3000, Presario v6000, HP Pavilion tx1000, Pavilion tx2000.
By the way, I just fixed my son’s Xbox 360 with red ring of death (error 74) using exactly same technique.
1. Laptop turns on with garbled video on the internal laptop screen and external monitor.
2. Laptop turns on as normal but there is no video on the internal laptop screen or external monitor.
The NVIDIA graphics chip soldered to the motherboard. When the laptop gets very hot, the NVIDIA chip separates from the motherboard and laptop video fails.
I have previous posts explaining how I fixed same problem by baking the motherboard in an oven or bubble-wrapping the laptop. But today I’m going to fix the motherboard using a heat gun. Basically, I’m going to heat up the NVIDIA chip with a heat gun to solder it back to the motherboard (reflow). I think this method is more reliable and the repair should last for a while.

There is no guaranty this method works all the time. While doing this repair you may damage the motherboard and make it unrepairable. Also, you may damage the laptop while taking it apart.
Proceed at your own risk and don’t blame me if you turned your laptop into a very expensive door stop. :)
If you don’t feel comfortable doing this repair, take your laptop to the repair shop.
First of all, you’ll have to disassemble the laptop and remove the motherboard. You can find laptop disassembly procedure in the service manual. If you having trouble finding the manual, leave a comment and maybe I can point you to the right direction.
In my example I’m using a motherboard removed from HP Pavilion tx2000 laptop.
In most laptops the graphics chip located under the CPU heatsink (and it has NVIDIA logo on it), so there shouldn’t be a problem locating the chip. The chip has a glossy top surface.

For this repair I’m going to use an Ecoheat heat gun EC-100.

In order to figure out how to position the heat gun and for how long, I tested it on a penny with a small piece of solder on the top.
The Ecoheat heat gun has a switch on the handle. There are two positions for the switch. Position 1 – slow. Position 2 – fast.
I used position 1 – slow.
I positioned the heat gun about 1 inch away from the penny and turned it on.

After about 40-45 second the solder started melting. After 50 seconds the solder melted completely.

To protect the motherboard from the heat I used a regular cooking aluminum foil. I cut off a piece of aluminum foil and folded it a few times to make my protection shield thicker. After that I cut off a square opening right in the middle, same size as the NVIDIA chip.
After I removed the heat sink, I had some old thermal grease stuck on the NVIDIA graphics chip. You can remove old thermal grease using alcohol swabs. It’s not necessary to make it perfectly clean. Just make sure there are no large chunks of thermal grease on the chip.

UPDATE: Some people mentioned that I should have applied some liquid flux underneath the NVIDIA chip for better results. I didn’t do it this time. I’ll definitely do it next time if the motherboard fails again. I found this video explaining how to apply liquid flux under the GPU chip. This video was made for Xbox 360 motherboard but should apply to any laptop motherboard too.
Liquid flux for GPU reflow available on eBay.
Finally, I positioned the heat gun above the NVIDIA chip about 1 inch away and turned the heat gun into the position 1.

After 50 seconds I turned it off and let the motherboard cool down for about 20 minutes.
Don’t forget to apply new thermal grease on the NVIDIA chip when you install the heat sink.
Some laptops use thermal pads instead of grease. If that’s the case with your laptop, make sure the thermal pad positioned correctly.
After I assembled the laptop back together, the video started properly!
The NVIDIA graphics chip problem fixed!
Will it last for a long time? I don’t know. Still testing.

Make sure to visit The NVIDIA GPU Litigation site.
It’s possible that your HP/Compaq laptop qualifies for a free replacement. Here’s a quoted from the site:
If you have an HP or Compaq notebook computer, you may be eligible to receive a replacement computer. A repair remedy is not available for HP/Compaq computers because replacement parts are not available. Replacement computers will be shipped 6 to 8 weeks after a claim is approved.

How to Stop Computer Problems in Your Office Before They Start

Okay sooner or later your office PC (personal computer) will have something go wrong with it. Like any other office machine, computers are subject to glitches, bugs and crashes caused by failing hardware or software. And in the long run your small business PC will be no different.

Just like in many home-based businesses, large modern offices have the exact same computer problems as a much smaller shops because they had the same “computer user” issues. All the computer users are mired in the “busy-ness” of the job at hand.

“Busy-ness” is what happens when working folks, like you and me, get caught up in using our business PCs day-in and day-out without taking the time to perform proper computer maintenance on them.
We lug around our laptops from home to car to office and back again without stopping. We download everything from music to maps without thinking about where these programs come from or what harm they can do to our business systems.

“Busy-ness” is the secret serial killer of technology and the biggest source of on-going computer problems. We slowly kill our technology with software that has not been updated in years, by downloading all types of viruses and spyware that is “attached” to more innocent applications and emails or by ignoring the signs of obviously failing hardware.

After all we are too involved in our “busy-ness” to take time to fix these “minor” computer problems…until it’s too late.

Unchecked computer troubles and poor computer maintenance will eventually lead to damaged or destroyed data files, lost work productivity due to hours of downtime. Not to mention costing you a fortune in computer repair fees.

So what can you do to fix computer problems before they get out of hand?

Fix Your Computer Problems Tip# 1 – Be Sensitive to What You Have. First, understand that your personal technology, your PC and the data and applications on it, are the lifeblood of your business. Take an inventory of what data files you have and what software you have installed. There are several free programs that can make this computer maintenance problem an easy fix.

Fix Your Computer Problems Tip# 2 – Be Aware of What You Download. The biggest problem, I have ever had both professionally and personally (hey I did it do, you know) was PCs with viruses or malware (malicious software) that were downloaded from “freebie” sites.

Free music, free software, etc. are great if you get them from a safe and trusted source, but no matter what you kind of anti-virus program you may have, like a vampire, malware loves it best when you “invite” them into your home.

Fix Your Computer Problems Tip# 3 – Be Certain You Update Often. Another problem that has always caused problems is failing to update your operating system or hardware drivers on a regular basis. Hackers never sleep. Somewhere in the world some greedy, little nerd is hard at work learning how to break into your PC.

Whether they hack your computer for fame (bragging rights) or fortune (to sell your stolen identity or credit card numbers), you need to learn to protect both your PC and more importantly your personal data. And one of the best ways to do this is update your operating system (OS) at least once a week.
Microsoft has a Windows update system that automatically downloads and installs updates and upgrades on your PC. Granted every once in while the Microsoft engineers mess up and release an update or upgrade that has some negative consequences, in the long run, their updates are one of the better way to safeguard your PC from outside attackers.

Fix Your Computer Problems Tip# 4 – Be Sure to Backup Your Business Files Frequently. I can honestly say, this is one biggest mistakes made in almost all small offices and businesses. We get knee deep in the “busy-ness” of making a living and then forget all about the data and files that make that business possible.
Think you can live without your hard drive? What if every single file, every picture, document or software program you have bought and paid or downloaded and installed, were to go, POOF overnight? It happens….

Now that you are aware of some of the problems of being too busy, you can set aside time every week to perform some simple computer maintenance tasks, so you will not have to fix more serious computer problems later on.

How to recover files from computer with crashed operating system

In this guide I explain how to recover files from a laptop (or desktop PC) with crashed, failed, damaged operating system.
1. The guide will work if your operating system damaged but the laptop (or desktop PC) hardware still works fine.
2. The guide might work if the hard drive has some minor damage, like a few bad sectors.
For this recovery I’ll be using a Ubuntu CD (Linux OS). Also, you can create a bootable Ubuntu USB stick and use that instead of the CD. Don’t worry, you don’t have to be a Linux guru for that. The interface will be very similar to Windows OS.

You’ll need another working computer to download and create a bootable Ubundu CD or USB stick.

1. Download the latest version of Ubuntu OS here. When you click on the download button you’ll start downloading an ISO image.
2. Burn this ISO image on a CD or create a bootable USB stick. It’s explained on the same Ubuntu download page, just scroll a little bit down.

3. Find the target drive where you going to save recovered files. You can use an external USB hard drive or USB memory stick. The target drive can be formatted with any common Windows file system: FAT, FAT32, NTFS.
Boot your laptop from the Ubuntu CD or USB stick. Simply insert the CD or USB stick and restart the computer.

If the laptop (of desktop PC) keeps trying to boot from the internal hard drive, you’ll have to enter the BIOS setup menu and change the boot order. Set your CD/DVD drive or USB stick as first device in the boot order. Safe changes and restart the computer.
From my experience, Ubuntu OS works fine with most laptop and desktop PC hardware and you shouldn’t have any problem booting it to the desktop. It may not work if your computer hardware is too new.
The computer will start booting from the CD or USB stick.
Now read carefully!

After some time a welcome screen will pop up. On this screen you can choose your language and choose between two options: Try Ubuntu and Install Ubuntu.

Select Try Ubuntu. In this case Linux OS will run directly from the CD or USB stick without changing any files on the hard drive.

Ubuntu OS will continue loading and after a while you’ll boot to the desktop, as it shown on the following picture.

In order to access the internal hard drive, you click on Places in the top toolbar. You should see your internal hard drive in the drop down menu under the Computer.

When you click on the internal hard drive a new window will open up. In this window you’ll see all files located on the hard drive.

Now plug in your target drive: external USB hard drive or USB flash drive.
Another window will pop up. In this window you’ll see files located on the external drive. In my case I have no files on the external drive, that’s why the window is empty.
You can move windows same way you do it in Windows OS. Arrange both windows as you like.

Finally, drag and drop needed files from the internal hard drive to the external drive.
After the transfer is done, you can unplug the external drive and use it on any other computer.

In case if your laptop (or desktop PC) has faulty hardware, you should try recovery with external USB enclosure.

Three of the Most Common Computer Problems

With computers being such an integral part of our day-to-day lives, it’s little surprise that computer problems can quickly turn our worlds upside down.  Having a computer that won’t turn on, one that’s unbelievably slow or one that is acting plain weird can be a frustrating yet all-too-common experience. Thankfully, with a little effort on your part and access to an expert computer support team, the most common computer problems can be resolved quickly and efficiently.

Believe it or not, one of the most common computer problems involves simply getting the computer to turn on.  So if you hit the power button and nothing happens, there are definitely a few things you’ll want to check. First, as obvious as it may seem, check the power supply.  Is your computer plugged into to the power strip and is the power strip turned on?  Ensure that the power cable is firmly seated in the power slot on the back of your computer as well.

If your power cables are all plugged in and connected, it’s time to start looking elsewhere for a diagnosis.  Does the computer come on but just not show anything on the screen?  If so, check your monitor cables, and also make sure that the cleaning crew didn’t inadvertently change your monitor contrast and brightness settings as they were touching up your workspace.

If that doesn’t work, it’s time to contact your computer support team. They can replace the computer’s power supply if it turns out to be the culprit, and they can likely troubleshoot any other potential causes.

Your computer ran as fast as lightning when you first got it, but now, it seems to take forever to do something as simple as open a new Web page or save your Microsoft Word document. What’s happening?  Before you contact your computer support technicians, check a few things for yourself.

A common complaint, slow computer problems are typically caused by a combination of simple things adding up.  Do you have lots of files in your Recycle Bin?  When was the last time you deleted files from your Temp folder?

Having leftover files cluttering up your hard drive can negatively affect your computer’s performance.  Also, performing a Disk Cleanup or Disk Defragmenter on your computer on a regular basis is a good idea; this process removes unnecessary files and streamlines your computer’s performance.

Check, too, to see how many programs your computer is loading on startup—you can do so by going to Start, then Run, then typing in msconfig.  Uncheck all but the items you really need to have available as soon as the computer boots, and you’ll likely speed up your computing experience.

Has your computer simply not been acting like itself lately?  If you’ve noticed your computer freezing up, giving you a blue screen, slowing down for no apparent reason or even doing something as annoying as switching the home page on your Internet browser, there’s a good chance you’re dealing with a virus or malware.

For problems like this, your computer support team can serve as an excellent resource to get you back up and running, but there are a few things you can do yourself.

First, ensure that your virus definitions are up-to-date, and then run a full scan of your system.  Next, run your anti-malware/anti-spyware program to see if it identifies threats.

Depending on what your software finds, you may be able to remedy the problem yourself by quarantining or deleting the offending files, but if you’re uncertain at all, this is one of those tasks that may be best left to your computer support technicians.  Don’t be afraid to give them a call.

How to fix video problem on HP laptops

In this post I explain how you can fix a known video problem on some HP laptops without actually taking it apart. Most likely the fix is not permanent but this will buy you some time, enough to backup personal files or even use the laptop until you get a new one. There is no guaranty this fix work 100%.
Here are some HP models affected by this known video failure problem: HP Pavilion dv2000, dv6000, dv9000, tx1000 tablet PC, Compaq 700, v3000, v6000 and probably some others.
If you know more models, please mention them in comments after this post.

As I know, the video problem somehow related to NVIDIA chip located on the motherboard. Overtime the NVIDIA chip separates from the motherboard and the laptop video fails.

When you turn on the laptop, all LEDs light up but there is no video on the laptop screen or external monitor. The laptop screen remains completely black and blank. The cooling fan spins as normal, on some models it stars spinning right away on other models after some time.
I found this trick mentioned by Walliot (comment 85) in this post. This trick called “towel fix” and used to fix “no video” issue in xbox360.
1. Remove laptop battery and hard drive.
2. Plug the AC adapter and turn on the laptop. Make sure the laptop is actually on, all LEDs should work.
3. Wrap the laptop with towels so all air intakes are closed.
4. Keeps the laptop wrapped in the towel for about one hours.
5. Unplug the AC adapter from the wall the let the laptop cool down (do not touch it for a while).
6. Unwrap the laptop and try tuning it on.
I didn’t really believe that this trick might work and tried it just because of curiosity but… IT WORKED!!!!
LAPTOP #1. HP tx1000 Tablet PC.

First, I tried this fix on a failed HP tx1000 Tablet PC.
I didn’t have paper towels at work but I had plenty of bubble wrap.
I closed the laptop in a tablet mode (with hard drive and battery removed), plugged the AC adapter and wrapped the laptop properly in bubble wrap.

After that I just waited for about two hours and unplugged AC adapter from the wall.
Waited for about 30 minutes and tried turning it on.
Success!!! The laptop started with video.

I just couldn’t stop and tried the fix on another failed laptop.
LAPTOP #2. HP Pavilion dv6000.
This is a different model with very similar failure symptoms. It turns on, all LED lights work but there is no video.
This time I didn’t something extra. To make sure there is no cool air coming into the laptop though bubble wrap, I closed all air vents with sticky tape.

After that I turned on the laptop from AC adapter (again with hard drive and battery removed) and wrapped the laptop base with bubble wrap.

The laptop was running like that for about 60-70 minutes but then I noticed that all LED lights went off. Not sure what happened, maybe the laptop overheated too much and shut down on its own. Anyway, I didn’t touch it for about 30 minutes and let it cool down.
My fix was successful again! The laptop turned on with video and booted to the desktop.

Here’s my understanding of how this fix works.
When you run a laptop wrapped in towels (bubble wrap in my case), it gets very hot because there is no air circulation inside the heatsink. The heatsink and GPU (NVIDIA chip) run so hot that it melt solder between the chip and motherboard and the video chip gets resoldered to the motherboard.
Now I have to test for how long this fix last.

Do's and Don'ts Computer Repair Guide

Troubleshooting Do's are extremely important to remember since they will save you money as you follow these steps to prevent damage and save you grief should you ignore any of these which may result in a problem showing up. Take the time to go over these troubleshooting Do's first and pay close attention to
removing any and all static buildup from yourself. Troubleshooting Do's consist of the following procedures.

DO make sure your hardware device drivers are up to date with any patches downloaded and installed. Take the time to visit your video card, sound card, motherboard, and other hardware manufacturer web sites to see if you have the most up to date device drivers.

DO check that all connections are seated firmly and properly in their sockets. This is a must check as these connections do tend to work themselves loose over time and cause problems you may blame on software.

If you have been working in your system unit recently and you noticed a fault manifesting itself, you want to go back and take a look at all connections you were near. Look to be sure your fingers did not press against other connections and causing then to work loose.

DO perform preventive maintenance on your computer and keep it clean regularly. Its a good idea to open up the system unit and remove all dust that have accumulated on the motherboard as well as all other boards.

Dirt and dust conducts heat and will cause the computer to run at higher temperatures than it normally would. Take a look at the vents in the back of the case and remove dust that have accumulated.

The best way to remove dust from all circuit boards in the system unit is by a can of compressed air, available at any computer store and now, most retail stores.

DO make absolutely sure you have removed any and all electrical static buildup from yourself before working inside your computer and before touching any new circuit cards and chips.

Please don't overlook this troubleshoot tip. It would be a tragedy to purchase new memory only to short circuit them either before you installed them or you do so the process.

How to Create Shortcut to Shutdown / Restart / Lock Windows 7 or Vista

 First right-click on the desktop, choose New and then Shortcut. image
In the shortcut location box, you’ll need to enter the correct command, which I’ve listed for you below.
Shutdown Computer
Shutdown.exe -s -t 00
Restart Computer
Shutdown.exe -r -t 00
Lock Workstation
Rundll32.exe User32.dll,LockWorkStation
Hibernate Computer
rundll32.exe PowrProf.dll,SetSuspendState
Sleep Computer
rundll32.exe powrprof.dll,SetSuspendState 0,1,0
When you’ve clicked next on the above dialog, you’ll be asked to name the shortcut. Probably best to name it according to the right function.
After you click Finish, you should now have a new icon that you can double-click to immediately shutdown, restart, or lock your computer.

Change Shortcut Icon
If you want to have separate shortcuts for each function you might want to change the icon. Right-click on the icon and choose properties.
Click the Change Icon button, and then you can pick from the available icons in the system, or you can use the Browse button to pick an icon you downloaded off the web.
Note that you can drag them to your quick launch bar if you’d prefer to have them there.

How to Backup/Copy Files that are "In Use" or "Locked" in Windows (Command Line)

If you’ve ever tried to copy a file that is locked by another application, you’ve probably seen an error message similar to “The process cannot access the file because another process has locked a portion of the file”. So how do you copy it anyway?
Since XP, Windows has supported a technology called Volume Shadow Copy, which is used to power the previous versions feature in Vista as well as System Restore and backups. What it does is take a temporary snapshot of the file or drive, and then allow an application to read from the snapshot even while other applications are accessing or modifying the file.
What we can do is use a command line utility called HoboCopy that utilizes this service to copy the file.

Understanding the Prerequisites
HoboCopy and most other backup utilities make use of two services in Windows, and you’ll need to verify that these services are not disabled:
  • Volume Shadow Copy
  • Microsoft Software Shadow Copy Provider
They can be left as Manual startup, so they don’t need to be running all the time. Hobocopy will start the two services automatically when needed, and the Volume Shadow Copy service will be turned back off after it’s done.

Using HoboCopy to Backup/Copy a Single File
The syntax is a little weird, because HoboCopy is really meant to be used for backing up an entire set of folders. We can use it to backup a single file by passing in the filename argument at the end.
Note: on Windows Vista you will need to launch an Administrator mode command prompt by right-clicking on the Command prompt in the start menu and choosing Run as Administrator.
hobocopy c:\directoryname\ d:\backupdirectory\
For example, I want to backup my c:\users\geek\mail\outlook.pst file to d:\backups\outlook.pst. Here’s the syntax that I’d use:
C:\> hobocopy c:\users\geek\mail\ d:\backups\ Outlook.pst
HoboCopy (c) 2006 Wangdera Corporation.
Starting a full copy from c:\users\geek\mail to d:\backups\
Copied directory
Backup successfully completed.
Backup started at 2008-03-09 01:57:28, completed at 2008-03-09 01:58:39.
1 files (606.45 MB, 1 directories) copied, 7 files skipped
Using HoboCopy to Backup an Entire Directory
A much more useful task would be to backup my entire User folder, probably to an external hard drive for safekeeping. For this, we’ll want to add a couple of command-line arguments.

/full Copy all files
/skipdenied Ignore any access denied messages because of permission errors.
/r Copy recursively
/y Don’t prompt, just copy everything

hobocopy /full /skipdenied /y /r c:\directoryname\ d:\backupdirectory\
Let’s go with the same example, I want to backup my entire user directory to d:\backups\, so I’d use this command:
hobocopy /full /skipdenied /y /r c:\users\geek\ d:\backups\
This command will likely take a very long time to complete, so you might want to take a nap or something. At the end you should have a nearly perfect copy of the directory… if there are any permission errors you’ll be alerted to files that didn’t copy. Realistically any files in your user directory shouldn’t have this problem.

Using HoboCopy to Incrementally Backup a Drive
Hobocopy also supports backing up files incrementally, so it will only copy the files that have changed since the last backup. This works similarly to utilities like rsync, except hobocopy stores the last backup date in a file that you need to specify on the command line.
/statefile=filename This flag specifies the file that contains the last backup information.
/incremental Only copy files that have changed since the last full copy.

hobocopy /incremental /statefile=filename /y /r c:\directoryname\ d:\backupdirectory\
hobocopy /incremental /statefile=d:\lastbackup.dat /y /r c:\users\geek\ d:\backups\
The first time that you run this command you will need to use /full instead of /incremental, or else you will get an error because the state file hasn’t been created yet. After that you can run the incremental backup with the /incremental switch.

This would be an excellent way to automatically backup a set of folders as part of a scheduled task.


If you are having problem using the command line you may try CopySharp, which is a GUI version tool for copying open/in process files. It is inspired by robocopy and vshadow. CopySharp V1.0 requires Microsoft Windows Server 2003, Microsoft Windows XP.

Allow Users To Run Only Specified Programs in Windows 7

I was doing some reading today and came across an interesting article that I thought I’d share with you. It’s about allowing users to run only specified programs in Windows 7. I think that this would be helpful to restrict programs you don't want others to use or execute on your own computer. This also prevents unwanted application execution like viruses and malwares thus keeping your computer safe and sound.

If you have a shared or public computer you might want to allow users to use only specified programs. Today we take a look at a setting in Local Group Policy that allows you to set only specified programs to run. Note: This process uses Local Group Policy Editor which is not available in Home versions of Windows 7.
First click on Start and enter gpedit.msc into the search box and hit Enter.
Navigate to User Configuration \ Administrative Templates \ System. Then under Setting scroll down and double click on Run only specified Windows applications.
Set it to Enabled, then under the Options section click on the Show button next to List of allowed applications.
A Show Contents dialog comes up where you can type in the apps you want to allow users to run. When finished with the list, click OK then close out of  Local Group Policy Editor.
If a user tries to access an application that is not on the specified list they will receive the following error message.
This is a nice feature for limiting what programs users can or cannot access on the computer.
