Cool, but a fellow hacker

gave me these snippets of code:
For 95/98/ME:
START C:\windows\rundll.exe user.exe,exitwindowsexec
For XP:
shutdown -r -c "Hahahah you got pwned by da Fox! Sucka!"
The one for XP should be the same for 2000, maybe not though.
Although, I am obligated to give points to VHockey for his nicely-sized tutorial on the subject.
