    Cannot open Task manager
    Hi,
    I'm not able to open the task manager. It appears for a second and then disappears when I press ctrl+alt+del or when I click on task manager from the task bar. What can be the problem? I use Windows XP professional.

    The Task Manager exe file might be corrupted. If you have a Windows XP CD, you could try replacing your current task manager with a fresh one.

    To do this, put your XP cd in the drive, and open a new command prompt (Start > All Programs > Accessories > Command Prompt).
    Type D: (if D is the letter of your drive), then type
    "cd i386" (without quotes),
    Then type
    "expand taskmgr.ex_ C:\WINDOWS\system32\taskmgr.exe" (again, without quotes)

    Close command prompt, restart your computer, and try Task Manager again. If that doesn't work, you could try a repair install of XP.

    This error is caused if the DisableTaskMgr restriction is enabled. To enable Task Manager, try one of these methods:
    METHOD 1
    Click Start, Run and type this command exactly as given below: (better - Copy and paste)

    REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Pol icies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f

    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.
