This .cmd (or .bat) script stops system clock on WinNT (=2000/XP/Vista):

:a
@echo %time%|time>nul&&goto a

Requires at least Power User.

If you want to use it for fun, run it via Task Scheduler (``at time command``) to hide cmd window.

Tired of that annoying system beep going off while you're typing away in vim? Turn it off with this command:

C:\> net stop beep
