I just found out(by accident) that you can use Windows 8.1 with no password at all, here's how-

Go to your lucky charms and click Change PC settings, click accounts-


Then you simply click Disconnect-


Then enter your current MS password-


And sign in to your local account, if you want to use a password you are much better off using a password in the BIOS on most computers, most Windows based passwords are pretty easy to get around. I'm hust going to use my fingerprints to log on, I can't forget them


There's probably something I've missed, I don't know much about computers.
