Windows 10: Computer takes 5 minutes to boot after KB4505903 update

Acer Aspire XC-704


Ever since I updated my computer with KB4505903 to 18362.267 yesterday, my computer would boot into the login screen normally. But after I typed in my password, my computer screen would be completely black with a mouse pointer for 5 minutes (I timed it with my watch) and then the computer would show the desktop screen normally.


And the Microsoft app store (Canada) would show the front page normally. But when I press "downloads and updates", the app store would have the circle spinning forever.

I suggest the following simple steps:

1. Set the autosave options in MS Office to a low value say 5 minutes.
2. Setup file history to autosave frequently - the shortest period is 5 mins
3. Install Macrium Reflect Free and configure it to do a daily incremental system backup
