Hello All

first time i seen this, but ok i downloaded RHEL6 Beta iso lastnight which downloaded fine, but i had to reboot PC to fix a Emailer issue so i did but when i tried logging back in with my Admin Password windows7 would not accept the password so i tried a few times making sure it was the correct password. then i gave up an rebooted into Safe Mode an logged in with the same password i tried before an logged me in,  fine, so i went an deleted the iso file an rebooted back into Normal Mode, guess what? yes it logged me in with the same password i tried with. any of you guys have any clues is to how that happened an why?
