I have a Toshiba laptop at home on which i recently installed Windows VIsta Home Premium. This system was having just one user account and that was Administrator's account. I haven't set any password for the same. Today when i was out, i guess my brother who is a newbie in computers might have messed up something due to which the system is locked now.
While trying to unlock the same it is asking me to insert USB flash drive or removable disk. I dont have any of such disk as well as no Idea what to do. Can anyone here please tell me how can i reset the account or unlock it?
