My father has a HP Desktop (roughly 6 years old, all original components) running Win Vista Home Premium. He went to get on one day and was completly locked out of his Administrative account with a message appearing saying, "The user profile service failed the logon. User profile cannot be loaded." But if he boots up in Safe Mode, he can log on, but there is a message that appears at the bottom saying "You are logged on under a tempoary profile default because the user profile cannot load." Now it's gone from not being able to just log on under the admin profile, to his Anti-virus saying it doesn't recognize his liscense code. I cannot turn on Windows Fire Wall, cannot uninstall any programs, cannot install any programs, I have no administrative control even after putting in the password authorizing such actions. I've attempted to edit and repair registry, but it will not allow me to do so. I cannot even create a new profile to try to back door it either. I ran a boot disk anti virus to see if it would pick up a virus, but it came up clean. I have scoured microsoft fourms looking for answers, and everything I have found has failed so far. A friend of ours who works around computers himself a bit turned me towards this forum. Any help would be appreciated. He also recommended a clean install of another windows program because to him it sounds like a really deep hack. If need be thats what we will do, we are just lloking for something that can help us avoid that if we can. Any help or advice again is appreciated. Thankyou.
