On the computer, how do I log on as an Administrator?

Question

i need to download something, but it won't let me download it unless i'm logged on as an administrator so how do I log on as an administrator?

Answer 1

if you're using windows XP home edition, you can log-in as administrator in safe mode. that's the only method, i think.

but if you're using xp professional, press ctrl+alt+del twice at the welcome screen and input your admin password in the classic login window that appears

Answer 2

you don't unless you know the password.
