2nd i would say yes you can activate the Administrator account using cmd in a rescue cd
run command prompt
type the following
net user Administrator /active:yes
erase any passwords for administrator
net user Administrator *
Enter
enter
then check the account is active by net user Administrator
and check for the line active
