Enable Disabled Task Manager

I recently had this trouble of an error popping up when I pressed the Ctrl+Shift+Esc keys on my keyboard which said:

"Task Manager is disabled"

This can happen due to a couple of reasons,
One: A virus/malware infected your computer.
Two: You do not have the rights assigned to access it.

To get access, all you need to do is:

• Go to Run ( Start-> Run or WinKey+R)
• Type "gpedit.msc"
• Go to Group Policy settings->User Configuration->Administrative Templates
• Select System->Ctrl-Alt-Delete options
• Double Click Remove Task Manager
• Set it to Not Configured.

And that's it, you are done!
