I recently upgraded from windows 8 Consumer Preview to Windows 8 Pro (RTM through dreamspark premium), and have the following issue:
When I attempt to log in after a restart, it often takes a while (~3 minutes) for the computer to accept the password (Each try goes relatively quickly, a few seconds at most before telling me I have an incorrect password).
I changed the password, and this issue is unresolved (the old password came with the upgrade).
What could be doing this?
