ModifyOk, for those of you that have tried this regedit command, "REG add
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v
DisableTaskMgr /t REG_DWORD", if it does not work, go here in the regedit....
HKEY_Current_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
(This is in Wondows Vista OS) Locate the Disable TaskMgr REG_WORD and change
the value to 0 (Zero) if it is set to 1. To change the value, RIGHT click on
the Disable TaskMgr then click Modify... I had a problem where I couldn't
select Task Manager, I didn't get any messages, it just wasn't highlighted,
or available from the Ctrl-Alt-Delete screen. I found the REG_WORD and
noticed it's value was changed to 1 so I changed it to 0 and guess what, I
have task manager back.
