How to Fix “Task Manager has been Disabled by your Administrator” Problem in Windows?

That's a very common problem for Windows users. Many times when you try to open Task Manager, you find that "Task Manager" option has been grayed out:


Also when you try to run it by typing "taskmgr" in RUN dialog box, Windows shows following error message:

Task Manager has been disabled by your administrator.


There might be 2 possible reasons behind this problem:

  • Your system administrator applied the restriction using Registry Editor or Group Policy Editor.
  • Your system has been infected with virus and it has disabled the Task Manager.

If you are already the Administrator of the system, then your system is most probably infected. You should follow the instructions given in following topic first:

Is Your System Infected with a Virus / Spyware / Adware / Trojan?

Now if your system in not infected or you have successfully removed the virus, then you can follow these simple steps to enable Task Manager again:

1. Type regedit in RUN dialog box or Start Menu Search box and press Enter. It'll open Registry Editor. If Registry editor is also disabled, then follow instructions given in following tutorial:

How to Enable Tools -> Folder Options and Registry Editor in Windows

2. Now go to following keys one by one:


and look for a DWORD value "DisableTaskMgr" in right-side pane. If you find it, delete it.


3. That's it. Now Task Manager will be enabled.

PS: If you are not familiar with editing the registry, then you can use ready-made registry script to do the task automatically. Download following ZIP file, extract it and then run the extracted .REG file. It'll ask for confirmation, accept it:

Enable Task Manager

  • You can also Restore your computer to a previous date (guessing when you last saw Task Manager was running). Worked like a charm.

    With Hitman Pro AND ESET, how can I avoid this from happening again? Second time it has happened. How can someone hijack my Administrator

  • super it awesome!!! now working fine

  • Every time I attempted to make changes in start up files msconfig xp told me that I needed to have Admin privledges (which I had)... resolved issue by booting to safe mode and running Malwarebytes.

  • I've tried about everything, but no luck. Couldn't find Disable Task Manager in registry files. I can see task manager on the task bar, and when I hover the cursor over it, I get the small window that shows it. But when I click on it, everything disappears. I'm stumped. I have Symantec anti-virus. Any suggestions?

  • thanks it works....thank you very much!!!!!!BRO

  • Thaaaaank you so much, wow.

  • thank you soo much for this manual! i was finally able to enable the taskmanager. whoever wrote this and posted it is th real hero!

  • Ok.. So I had a virus and i solved most of the stuff.. Regedit works.. Taskmanager Works.. All I wanna know is the names of the other files in the locations in regedit by default so i can remove other ones.. I got some sketchy ones but I don't wanna delete them ( Might just be how windows names things ) . One of the simptons still is when i'm in a game ( like csgo ) and i alt + tab... My mouse dissapears. Also In some menus in other games. Another one I got is it says Alahu Akbar every time I start my PC. I'm guessing just a program that runs when i start- I'l try solving that in Safe Mode. Thanks For All The Help ! :D

  • It worked for me.

    Very Simply and Comprehensive Solution
    Thank You Very Much

    You saved a hopeless man's life.
    First run windows security essentails more then e few time until it says computer is clean
    Then run "unhookexec.inf"

    That's all.
