I usually don't post my computer issues withought looking it up/working on it myself. I tried it a little before i whent to work but to no avail. If anyone could help me, i would appreciate it.

When i try to run programs that modify my registry, or even get into regedit it comes up with the following error.

"Another program is currently using this file"

Also my ctrl+alt+del isn't working, so i can't disable whatever is using it.

Any help would be appreciated, thanks.

start, run

c:/windows/system32/taskmgr.exe
