Task Manager grayed out.

I have a computer that had a virus that disabled the use of task manager under a certain profile but it still works under everyone elses profile. I have run out of ideas on how to re-enable it for this person. I have tried reseting all local polices back to default but that didnt' seem to fix the problem. Any suggestions?

Rename the user's profile and then have them log on again to create a new one.  Then, copy their Favorites and other stuff back from the old profile.  What do you think?

First make sure that the group policy is not set to disable task manager.  Then check the registry key.  See below how to do both.

From this Site: http://www.windowsnetworking.com/kbase/WindowsTips/WindowsXP/UserTips/Customization/EnableDisableTaskManagerinWindowsXPHomePro.html


Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\Windows\CurrentVersion\Policies\System
Name: DisableTaskMgr
Type: REG_DWORD
Value: 1=Enablethis key, that is DISABLE TaskManager
Value: 0=Disablethis key, that is Don't Disable, Enable TaskManager

As part of the enhanced management available in Windows 2000 and Windows XP, rather than risking a registry change, as an administrator you can enable or disable Windows 2000 Pro or Windows XP Pro's TaskManager using Group Policy Editor. This can be applied to the local policy. Note: if you are trying to override your organizations group policy, you can't. As soon as you re-authenticate to the domain, the domain or OU Group Policy will rewrite the registry setting. But if the TaskManager was accidently disabled or you need to control this item for a set of standalone boxes this is for you:

Click Start
Click Run
Enter gpedit.msc in the Open box and click OK
In the Group Policy settings window
Select User Configuration
Select Administrative Templates
Select System
Select Ctrl+Alt+Delete options
Select Remove Task Manager
Double-click the Remove Task Manager option

And as I mentioned above, since the policy is Remove Task Manager, by disabling the policy, you are enabling the Task Manager.

Got XP Home - use the registry edit.

If the reset policies don't work you may try recreating the users profile.
To do this, log on as yourself (Admin rights needed) and rename the users profile. I usually rename it to: Username_old.
Then, log on as the affected user and test.
If it works, open the old profile and copy the required data, desktop settings, IE Favorites, etc. to the newly created profile.

Hi there,

Try this

it's a txt file, rename to .reg and it should help.

Hope this helps

Oh and the content of the file is as follows

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000000

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000000
"**del.DisableTaskMgr"=" "

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\]
"DisableTaskMgr"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"DisableCAD"=dword:00000000
