Task manager problems

[Umberto]

When I try to end some non-responding programs by opening
task manager, it says that my task manager has been
disabled by my administrator. How come? Which
administrator? Network administrator? If there is any way
to enable it again, it'd be great. Otherwise, I'll have
to format the PC. Thank you.

Click Start, Run and enter REGEDIT Go to:

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

Look in the right pane for a value called DisableTaskMgr. If it exists, it
should be set to 0 (zero). If not, right click DisableTaskMgr and select
Modify. Set it to 0. If it doesn't exist, right click in a blank area of
the right pane, select New, DWord value. Name it DisableTaskMgr and leave
it set at 0.
