I came across this one but haven't tried it yet. Does it stay in DOS even after a reboot ?

No, it just gets written to ram and goes away with your next reboot.

okay, I tried the timer tick on Vista, but it was acting weird. So I thought it was going to stay like that. Ofcourse I know how to remove it. But thanks though.
