Using version 2.6.3, I decided to stop the repair at this point on my Dell Venue 8 Pro. It corrupted the operating system so that IE and most of the "Modern Apps" would open and close immediately. I tried to do a system restore and found that there was such corruption that it would not work. I also tried a system reset and that would not work, either, I eventually had to send the tablet back to Dell who repaired it by reinstalling the operating system.
DO NOT STOP THIS REPAIR. IT MAY CORRUPT YOUR COMPUTER SO THAT YOU WILL HAVE TO REINSTALL EVERYTHING.
