I hace a acer aspire 5610.
When i turn computor on i get new usere box and owner box on the screen.
It says that this copy of windows must be activated with microsoft before i can log on., i click to confirm then it says windows has already been been activated, click okay to exit, This i do by clicking in the box bottom right hand of the box displayed, then it says owner logging off, then it just goes back to the original 2 box's that says owner and guest i have no disc for back up, also tried to go to restore to a earlier date in f8 but no joys, hope that this is now clearer for you sorry
The system likely has the restore disks on a partition on the hard drive. Since you don't have any files on it yet, a complete system restore would reset to its new condition and should allow you access to configure/register/activate the system.
