Windows 8.1 message "We couldn't complete the updates, undoing changes, don't turn off your computer"
Greetings,
I installed updates in my Windows 8.1 partition. Then it asked me to restart the computer and the message "We couldn't complete the updates, Undoing changes, Don't turn off your computer" appeared and has been on the screen for hours. I thought about reinstalling bootcamp but I have software in the Windows partition that cannot be recovered. I have read that one fix is starting Windows in "Safe Mode", but this is not possible. I am using a MacBook Pro (Retina, 13-inch, Early 2015) OS X 10.10.5
How do I fix this issue without wiping the Windows partition and losing my software?
Thanks!
