I set up my new Windows 8 system and used an email I don't want as a primary account alias. 

I tried to switch by signing up with the email I want to use.  But I didn't do it correctly and deleted it.

Now when going to create a new alias that I can switch my primary account over to, it says my email is already taken.  But I deleted that account and can't even sign in with that email anymore.

Please advise.  I really want to get this taken care of.
