Please allow me to try and explain the problem since this is not my machine at fault. After the anniversary update on this Dell laptop ( unknown model but only 6 months old), the only way to sometimes be able to log in is to use the Power icon on the Right side of the screen to restart the machine. If you power up normally, the boot continues until the password challenge displays. Entering the password causes the rotating circle and then the password challenge re-appears.
Sometimes the re-start will not work unless the laptop has been OFF for 1-2 days.
This was purchased on QVC. There is no D drive with an original image and when Dell was called for service they had no record of the machine. Calling QVC for the certificate was a black hole. They state one was sent and now it is a catch 22 since the owner says they never received one.
A while back I re-installed an iso of an earlier Win 10 only to have this problem re-appear.
Any help would be great.
Best regards,
