I am helping a friend with a Toshiba Satellite L30-113 running Windows XP Home. I set the machine to automatically log on using run "control userpasswords2" and installed SP3. However somewhere along the line after a reboot all administrator accounts have lost their privileges. There are only 3 accounts I can log onto and none have admin privileges. control userpasswords2 is no longer accessible from any account and without admin privileges I can't install any new programs or updates or do a defrag etc. I can't log on to the original Administrator account as there is an error message Unable to log you on because of an account restriction. I have tried booting up with PClogin now to remove all passwords and reset all accounts as administrator but that failed. I still cant log on as administrator. The other account I was using did have administrator privileges but they have been lost. I have run Malwarebytes to remove all threats (thankfully it was previously installed). I have also tried to reset file permissions using SECEDIT.EXE Link has been removed This did not work I have downloaded he Download the SubInACL tool and tried the fix halfway down the page here: Link has been removed This did not work Any thoughts and suggestions would be appreciated. Kind Regards Chris
