Computer Errors - Task Manager


When you try to open Task Manager, the following error may occur:

Task Manager has been disabled by your administrator


This error is caused if the DisableTaskMgr restriction is enabled. To enable Task Manager, try one of these methods:

IMPORTANT: If this restriction was enabled in your system without you doing anything or without your knowledge, then it's highly likely that a Virus has blocked the usage of Task Manager in your system by enabling the DisableTaskMgr policy via the registry. I strongly suggest that you perform a thorough checkup of your system immediately. Steps listed in the Resolution section of this article helps you unblock the Task Manager, but that does not remove the Virus (if any) from your system.

Method 1

Click Start, Run and type this command exactly as given below: (better - Copy and paste)

Method 2

Download and run this REG fix and double-click it.

Method 3

  • Click Start, Run and type Regedit.exe
  • Navigate to the following branch:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies\ System

  • In the right-pane, delete the value named DisableTaskMgr
  • Close Regedit.exe

Method 4: Using Group Policy Editor - for Windows XP Professional

  • Click Start, Run, type gpedit.msc and click OK.
  • Navigate to this branch:

User Configuration / Administrative Templates / System / Ctrl+Alt+Delete Options / Remove Task Manager

  • Double-click the Remove Task Manager option.
  • Set the policy to Not Configured.

Always check the SUPPORT part of the company website for help FIRST! After all they should know best and often they have a troubleshooter that you can follow through to help you figure out what is wrong.

WINDOWS VISTA: Retail, Upgrade or OEM???

Windows Vista: Retail, Upgrade, or OEM version?

If you’re not confused enough by all the versions of Vista, the upgrade choices might just do it. I predict Home Premium will prove to be far and away the best seller (for home users). Home Basic has too many features stripped out, it may become just as maligned as Windows ME. Ultimate is too expensive, unless you have the need to connect to a domain or are an enthusiast that just have to have every feature (like me).

So, you’ve decide you’re going to purchase Windows Vista Home Premium. Wait! You’re not done. Do you want the full-retail version, the upgrade version, or the OEM version? The obvious difference is price. Most places are selling the full retail version for about $230, the upgrade for about $150 and OEM for $120. So, just what is the difference?

Full Versions can be installed on any system, whether it’s a new system you just built with no operating system, or a system with any previous version of Windows installed, or any other operating system. You can also upgrade or change that system and reactive Windows as many times as you would like. Includes both 32 and 64 bit versions (to be installed on one PC).

Upgrade Versions must have Windows XP already installed on your hard drive of the system that you plan to install the upgrade on. Windows 2000 is also eligible for the upgrade (although a clean install must be performed), earlier version are not. Windows XP only required that you possessed the media from an earlier version (a CD for example). The new requirement with Vista is that the earlier operating system must be installed on the hard drive you’re upgrading. After Vista is activated, the XP key that was upgraded becomes invalid. You can’t use that key to install XP on another system, or in a dual-boot configuration. For example, say you purchased the upgrade edition to install on a new system. You must first install and activate XP, and then use the Vista DVD to upgrade. After which you can’t use the XP key again. Both 32 and 64-bit versions are included (to be used on one system). Link to: Upgrade Matrix

OEM Versions are intended to be sold to Original Equipment Manufacturers. There is no phone support from Miscrosoft provided, no retail packaging, and no manual provided. Support is supposed to be come from the system builder. An OEM version will allow either an upgrade or a clean install. You must chose 32 or 64-bit verisons, they are not both included like they are with the retail vesions. Finally, OEM licenses can’t be transfered to another system. You can’t transfer from an old computer to a new one. If you upgrade your system, you’re limited as to what you can change, and how many activations you’re allowed.



If you choose to purchase an upgrade version of Windows Vista to upgrade XP, you will no longer be able to use that version of XP. Either on another system, or as a dual-boot option. The key will be invalidated, preventing activation.

From Vista’s EULA found here (PDF) :

13. UPGRADES. To use upgrade software, you must first be licensed for the software that is eligiblefor the upgrade. Upon upgrade, this agreement takes the place of the agreement for the software you upgraded from. After you upgrade, you may no longer use the software you upgraded from.

For many people this may not be a problem, but it’s a change from earlier versions of Windows.

Update: Workaround posted here!

Workaround For Clean Install With Vista Upgrade DVDs

ActiveWin published a workaround provided by Microsoft internal documentation for Vista Upgrade DVDs that will not invalidate the Windows XP Key, as discussed here.

Edit Update: As noted in the comments below, Blair provided the original source, not credited by ActiveWin, as Paul Thurrott.

“Per Microsoft’s new licensing requirements for Vista, users are required to install a Windows Vista Upgrade from within Windows XP. When this occurs, the Windows XP license is forfeited and the Windows Vista installation process can take place. Now, however, this workaround allows users to perform a “clean install.” The process is a bit tedious, but is not hard are all to complete. Users have to perform these simple steps to perform a clean install of Vista without a previous version of Windows installed with an upgrade DVD:

1. Boot from the Windows Vista Upgrade DVD and start the setup program.

2. When prompted to enter your product key, DO NOT enter it. Click “Next” and proceed with setup. This will install Windows Vista as a 30-day trial.

3. When prompted, select the edition of Vista which you have purchased and continue with setup.

4. Once setup has been completed and you have been brought to the desktop for the first time, run the install program from within Windows Vista.

5. This time, type in your product key when prompted.

6. When asked whether to perform an Upgrade or Custom (advanced) install, choose Custom (advanced) to perform a clean install of Vista. Yes, this means that you will have to install Vista for a second time.

7. Once setup has completed for the second time, you should be able to activate Windows Vista normally. You can also delete the Windows.old directory which contains information from the first Vista install.”
