My Windows 10 Home desktop machine downloaded the anniversary update this afternoon and completed the first part of the installation process. It then switched to a screen that says "Working on updates xx%; Don't turn off your PC. This will take a while. Your PC will restart several times."
The percentage completion gradually increased to 82% over an hour or so. It now has been at 82% for about 6 hours. There's minimal hard disk activity now. What can I do to get out of this frozen update process. I haven't tried the power switch or pulled the plug. Is there some way of gracefully exiting the process that is less likely to inflict injury on my operating system or data?
Thanks for any help.
