Ok...here is the issue.  I am using Windows 2012 essentials at home (Server Domain 1 "SD1" and Server Domain 2 "SD2")...I was moving from SD1 to SD2 and was asked to remove my self from the SD1.  So I went to Computer Properties and put myself in a workgroup and rebooted.  This is when the problems started.  By default when you reboot the Win8 machine...the login screen defaults the last user at login.  This user was a domain user...and does not exist on the local machine and I can not figure out how to get to a user on the local machine.  I can't log in.  How do I get to a different user at the login screen?  Backspace does not work...control+alt+Del does not work...how can I get to a local user list?

Nice Huh?

There should be an arrow on the left side of the account picture in logon screen. Click the arrow to log on with another user.

I don't have an arrows on any of my Win8 Pro machines

Is there f8 functionality on Win8 to go to repair...of do I have to boot from the install disk?
