My friend recieved an old computer from a school and when he goes to start up the computer it loads fine and everything except it asks for a username/password. We have no clue how to get past this.
With out tring to hack in to it you would prob. be better off formatting and reinstalling the os of your choice. Unless it is like a bios password(then you have to find out from the school). If it is a windows password if you just got the computer from the school it prob. has a bunch of junk that you woudnt use anyways so i would just blow it away and dffr.
then to get the password screen off you would either have to login after knowing the password /login name and change it not to ask you for the password or reinstall windows. In which case you said that you couldnt get the password so all I can think for you to do is reinstall windows
