this is a new trick:
Hiding the Last User Logged On in windows:

If you use the standard NT style of login and want to hide the last user:

1. Go to RUN and write"gpedit.msc"
2. Go to Computer Configuration >Windows Settings > Security Settings >Local Policies> Security Options
3. Scroll down to Interactive logon: Do not display last user name
4. Set it to Enable
