Q: Task Manager is grayed out how do I enable it?
A: You can control the use of task manger with the following registry key.
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System\DisableTaskMgr
It should be a DWORD value of 0=enabled 1=disabled
If it’s set to 1 and you change it to 0 be sure to refresh the registry view and see if it changes back to 1. If it does you might have some nasty malware controlling task manager.
