Task Manager Doesn't Open/Appear

Jacee, Yes. Vista Home premium 32 bit :)

I also tried the solution provided by Microsoft (attached).

First: My computer doesn't have a virus.
Second: On the regedit, there's no DisableTaskMgr in the options.
Third: I tried to search for gpedit.msc and no results found.

Great! Should I just throw this laptop in the middle of the ocean!? :)) Jk.

I'm using IoBit Advance SystemCare Ultimate and use the Process Manager there but I sill want to fix this Task Manager issue..

:) Thanks! :)

I also run SFC but it always stops at 80%..
