Kees' suggestion then.

Since this is a sign of malware damage run your anti-virus and anti-malware scanners. If you can't boot up, use your anti-virus software's rescue CD.

If you don't have one of those, try AVG's;

Did you already try Safe Mode?

That could very well be caused by a virus. And removing that virus might not undo the change in the registry it made.
Did you already run one of those antivirus CD's?

Easy fix is to ...

Click Start, Run and type the bold text below exactly as given, it is all one line! : (better yet - Copy and paste the bolded text into your Run box)

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f

Next easiest, you can follow this link and download then run a REG file to do the same thing (since it is a REG file you may or may not get some warning message about potential malware but it is not malware)-

or Easy but a bit more time consuming, you could fix things with a manual registry edit as follows:

1. Click Start, Run and type Regedit.exe
2. Navigate to the following branch:

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

3. In the right-pane, delete the value named DisableTaskMgr
4. Close Regedit.exe

The advice to scan for malware is sound and SHOULD BE DONE as it is generally malware that disables TaskManager but a malware scan doesn't generally re-enable it.
