Cannot open Task Manager - it is said that an administrator has blocked it's use.

It's been a while since this happened.  I just found this service, so I would ask.  I used to use program manager frequently.  Then I had a security breach? virus? - and when I try to bring up the program manager now, the message basically says that my administrator has blocked my useage.  This is a private computer with no administrator but myself.  I tried to log in as 'Administrator' but still got the same message and not able to open the program manager.  Any help?

If you see things like this:

You do not have sufficient security privileges to restore your system.
The System Restore tab is missing from the my computer properties.
System Restore has been disabled by group policy.  To turn on system restore, contact your domain administrator.
The System Restore tab is available, but the turn off System Restore (disabled by Group Policy) box is grayed out.
The task manager has been disabled by your system administrator.
The registry editor has been disabled by your system administrator.
The task manager has been disabled by group policy.
The registry editor has been disabled by group policy.
The command prompt has been disabled by your administrator.  Press a key to continue...
The operation has been cancelled due to restrictions in effect on this computer.  Please contact your system administrator.
The "Run" option is missing from the start menu.
The option "Log off."... ' is missing from the Start Menu.
Add or remove programs hs are limited.  Please check with your administrator.

The usual advice are something in the sense of "something has been disabled in the group policy...". ", and it is probably true that something has been disabled, but you know what something is and what it takes to do about it.

If you are using XP Home Edition, you will get away with advice to use the Group Policy Editor, because there is no Group Policy Editor in XP Home and that really doesn't tell you where to look in group policy, even if you run the Group Policy Editor.

You need a complete solution that works for all versions of XP and requires no hunting around in the Group Policy Editor or registry to find where things are that have been disabled.

Unless you have disabled these things on purpose, chances are good that your system has a malware infection.  The malware knows what tools you use to try to find and remove, for the malware disables the things you are more likely to consume and prevents them from running if you can't find the malware and remove it.

If your system has this kind of affliction, all malicious software tools you currently use or have used failed to protect your system so that you can expand your horizons malware detection and prevention to prevent these kinds of afflictions in the first place.

The malware will be happy you trick into thinking that you need to so something drastic to fix your system - as a facility repair, system restore point or a total reinstallation of XP.  This is what it would be like you, but these measures are not necessary.

You must solve the immediate problem of the tools does not, then scan your system for malware when you are finished.

No matter what kind of malware you've used analytical tools, they are unlikely to solve this problem, because they cannot tell if the changes made to your system have been on purpose (you or an administrator who makes them) or some malware changed them, so the analysis tools will let these things alone (it's usually a good thing).

If your system is afflicted in this way, there are probably other things that also do not work - like the registry editor, System Restore and the command prompt, so fix them all at once even if you have not discovered they are broken again.

These commands from registry removes the registry entries that are stop opening programs.  Although the registry entries do not exist, these commands are safe to run and will work for all versions of XP.

Save the new text file with extension .reg on your desktop or somewhere you can remember with a name you can remember, something like:

After you save the file, close Notepad.

Locate the file enableit.reg on your desktop and double-click it.

Alternatively, you can right-click on the enableit.reg file, choose open with... and select the registry editor.

Answer in the affirmative to the question... Are you sure you want to add the information in the registry?

You should then see a message that information has been registered in the register.

Reboot your system and test.

You can delete the enableit.reg file when you are finished.
