Windows user only !
Do you know that ..
while XP Setup is installing the Windows with your device( not copying one in the blue screen)
you can spawn command prompt by pressing Shift+10
What to do then ?
You can open anything stored in system32 directory.. (coz system32 is filled after the copying session)
(Telnet, ping, iexplore, even games like solitaire and minesweeper)
Interesting, eh ?
