Hi, I am the only Administrator on my home pc, somehow after I installed my updates & shut down, the next day I couldn't logon. Now I find myself using the 'guest' user as my source of doing things online....My issue is:How can I change my password, being that I am the only Administrator. I keep getting about 20 pop-ups about 'parental permission' at a time...why is that, & what else can I do to get back on track. I can't even download anything being a 'guest user'without having being asked 'parental permissions' to unlock & make changes. I have been 'Locked-Out' literally from my pc, because all my files won't load to make Any change whatsoever. Please help me, Anybody. My computer is an 'Acer'...which did Not come with any recovery disks...
