Just did a system restore to go back to last evening before I installed a driver for a USB video card. Took a few minutes and then rebooted and is now at "Welcome" (with the little circle that replaced the hour glass going on). It's been at this stage for about 45 minutes now. Is this normal? Is it still doing part of the restore? I was reluctant to interrupt it as the last warning windows gives before starting the system restore is "Do not interrupt this process". I have though heard of people retiring, having grand children and passing on - while obeying this windows warning. Should I be interrupting this?
