I'm sure you can see the problem. Hotmail accounts are quite attractive to scammers. If you use a Hotmail ID for your Microsoft Account and your Hotmail account gets hijacked and the password changed, Windows 8 lets you log on to your PC, but when you do, you get the notice "You're signed in to this PC with your old password. Sign in again with your current password, or reset it." If you then try to reset your password, you can't -- clicking on the Reset link doesn't do anything.
I've encountered some problems that appear to be beta bugs -- the "Sign in again" notification comes and goes, for example -- and it isn't clear if there's a time limit on how long you can continue to use the old password. (I've let it run for 12 hours without being blocked.) But until you can provide the hijacker's password, you're locked out of all Microsoft Account access.
