When you're at the login screen, press ctrl/alt/del twice, it should bring up a classic login screen, enter administrator into there.

Safemode should be accessable with that though I think

Grab the ALL tables, for LM/NTLM hashes and you'll have the pass in an hour or two. If you do this a lot then it's worth downloading the tables, if you ever run into this problem again you can solve it quickly.
