Is there any way to force Windows 10 into F8 boot menu without first having modified it within the operating system? Cannot get into system at all.
I found that if I bind a key combination in System Preferences -> Keyboard -> App Shortcuts for Parallels to Menu Title: Reset and something like control-option-command-shift-D for quick resetting, I can then use this to force it to go into Automatic Repair. This then allows me to get into "Advanced options".
Following this I used "Go back to previous version" and Windows is working again. I then changed the network interfaces to be metered connections to prevent updating without permission through Winaero Tweaker (Network -> Set Ethernet as Metered Connection: Enable "Set Ethernet as metered connection"). While I was in there I also changed Boot and Logon -> Boot Options and I enabled "Turn on Windows 7-like boot menu" to prevent having to take drastic boot options (constant reset) in the future if something happens.
This is a terrible solution, but it is the only thing I've found to keep Windows working right now.
