Task manager has been disabled by your administrator



The first problem I ran into in cleaning up after my infested Windows XP image was this error message. One of the first things I do in cleaning an infested system is try to kill off running process that look suspect (or at least identify them.) On using ctrl-alt-delete I got the message “Task manager has been disabled by your administrator” To be honest I haven’t seen that one before and it sent me Googling…


It turns out it’s an easy fix. There is a registry key that can be set to enable/disable the task manager. There are a number of ways to fix (open regedit and navigate to the key and change it, download a .reg file and run it, or the following….) I found the most convenient to be to do the following….

Go to Start…. Run… type in this (without quotes) “REG add HKCUSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem /v DisableTaskMgr /t REG_DWORD /d 0 /f”

Fortunately the run menu remembers what you’ve used previously, as I had to repeat this after each reboot for a time. (Until I killed off all the pests from loading at boot.) The above worked to allow me to ctrl-alt-delete and get the task manager. After which I started looking for suspicous processes running.
