Description: My task manager has a "task manager has been disabled by the administrator" message. How did this happen and how can I correct this?


Why: if you didn't do it yourself, the news isn't good.

How to fix it: there are a couple of ways.

Let's look at this more closely.


Directions

So, how did this happen?

As we'll see in a moment, there are settings you can access as an administrator that would allow you to disable and enable Task Manager in this way.

You didn't do that, you say?

Then a virus probably did.

Disabling Task Manager is one way viruses try to make it harder for you to deal with their infections. Before proceeding any further, you should run a complete and up-to-date anti-virus scan of your machine. It's possible, perhaps even likely, that you've been infected.

Once you come back virus-free, you can proceed with the fix.



If you have Windows XP Pro, there's a nifty user interface to directly edit the setting you want to repair. Click Start, then click Run and type in gpedit.msc:

And press OK. This runs the Group Policy Editor.

Once in the Group Policy Editor, expand in turn:

User Configuration

Administrative Templates

System

Ctrl+Alt+Del Options

You should see something much like this:

It should be enough to click on Not Configured and then OK and Task Manager is available once again.



If you don't have Windows XP Pro, then you'll need to edit the registry manually.

Click Start, then click Run, type in regedit, and click on OK.

Expand these registry keys in turn:

HKEY_CURRENT_USER

Software

Microsoft

Windows

CurrentVersion

Policies

System
