Can someone help me please!!!! My windows task manager is disabled, everytime i press ctrl+alt+del, it comes up task manager has been disabled by administrator. How did i do it, if i even did it? only i use the computer, so how could i have done it? and how do i enable it again? i dont really know that much about computers, but i'd really appreciate it if someone could help me please!!!

go into disk management, services.
see if the task manager somehow got disabled there

There are viruses that will cause this problem, so if you haven't already, get one, update it let er rip. See what it finds.

There is a manual registry fix if all else fails here:

I would lean towards a virus however.
