Mine was in the 70% range when both my browser and the windows update both quit. Relaunched settings, windows update was blank. But I didn't reboot my computer right away. I spent another 20 minutes on my computer --- trying to see if it would finish the update in the background.
Then reboot first time, windows update was still blank.
Complete shut down, windows update showed update is finished but need to restart.
Restart my computer, windows update finished successfully.
