Task Manager mysteriously disabled

2006. However whenever I press Ctrl + Alt + Delete, the Task Manager doesn't appear but instead I get a
message saying "Task Manager
has been disabled by your
I'm the only user on my laptop and I didn't assign any
guest or other user. How do I fix
Answer : On some occasions, we found
that the Task Manager has been
disabled when the PC is infected
with a virus, spyware, trojan, or
other types of malware.
Malware creators like to disable the Task Manager to make
system troubleshooting difficult,
and also to make it hard to
remove their malware.
Ramesh Srinivasan, a Microsoft
MVP (Most Valuable Professional)
covers this issue on his website at
"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,"
Srinivasan said on the site.
He suggests that "you perform
a thorough checkup of your system immediately".
The steps listed below will
unblock the Task Manager, but
will not remove malware (if any)
from your system:
1. Click Start, Run and type Regedit.
2. Navigate to the following
registry branch: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System.
3. In the right pane, you should
see a line called DisableTaskMgr.
4. Double click on DisableTaskMgr and change
Value Data to 0 (zero) to re-enable Task Manager.
5. Close Regedit.
By the way, you can also
launch Task Manager by using
this keyboard shortcut: Ctrl+Shift+Esc.
