my college library usb is protected by admin password, i cant use pen drive please help, i want to hack it

enter in safe mode (F8) and change password, very easy..

it does not worked mate i tried!! really sad any other way buddy

it works for me...i hacked my friends user account multiple times and gained admin privileges

when you boot to safe mode, doesn't it ask you to login either as Adminstrator or normal user?

you're suppose to login as Administrator, then you change whatever you wanna change

I havent used xp in a long time but from what I remember there should be a hidden account called 'Administrator'. You can log into it when in safe mode or press alt+ctrl+delete at the welcome screen after a fresh boot or restart (just logging off from current account might not do) and type Administrator in account name and leave the password field blank.

Another method: You need to have access to any account other than the 'Guest' account. This method can be used to change the 'Administrator' password too. If guest account is the only thing you have access to, you can still give this a try, if this doesn't work go to google, you will find tons of methods.
In cmd
type this

Code:

net user

This will give you a list of all the users account
example

Code:

Administrator     user1    user2    professionaln00b

Now type

Code:

net user professionaln00b *

It will ask you for the new password and then to reconfirm it.
You can just press enter both times to take off the password completely or you can also give your own password.

or boot from a live cd/usb if boot from cd or usb is allowed.
if that is also disabled from bios options, you could try changing it if bios doesnt have a password, else reset the bios if you can (take off battery that gives power to the bios)
There are many more ways.
