Press ALT-CTRL-DEL twice to bring up the login screen (not the welcome
screen) then login as the administrator, which hopefully you didn't disable,
and for which you ideally have the password
Taking a long shot guess at logging in with the support account, if you
didn't set a password, then shouldn't you be able to login with that account
with a blank password? Just guessing...
i acedently disabled all the acounts exept the support one and now i cant
log
on my computer
