JSI Tip 10630. When you press CTRL+ALT+DEL, Windows XP reports that the Administrator has turned off your access to Task Manager?

If you receive a message that indicates that the Administrator has turned off my access to Task Manager, but the Administrator didn't do it intentionally, you can log on with administrative privileges and  run FixCAD.bat, which contains:

@echo offsetlocal ENABLEDELAYEDEXPANSIONcall :setcomp>nul 2>&1FOR /F "TOKENS=*" %%a in ('REG QUERY HKU^|FIND /V "_Classes"') do ( set line=%%a if "!line:~41,1!"
