I have experienced two instances where W10 became a bit damaged and would not install the next big featured update. It was still n a mostly usable state still , but the fix had to be a clean reinstall of latest version from dvd or usb. That is very quick and easy nowadays. 15 minutes only for an install to SSD whereas a big feature update via windows update can run for hours and leave you with windows old folders wasting many GB.
If you plan it. And backup all that you will need. Like app data folders, email folders. It is painless. I use mailbird pro wth multiple email addresses and all I have to do is backup and restore one app data folder to replace a full history and a full set of passwords. Google Chrome is very good at restoring settings if you have signed in and synced to cloud beforehand.

(Mostly usable e.g i got into a situation where netflix would not work in Microsoft edge and hours of tinkering, Googling could not sort it. Then I rashly messed with registry backup restore tools and totally broke it .
Fast clean reinstalls are the way to go, treat yourself to an SSD windows drive at the same time...you will never want to go back to list slow spinning discs once you experience that.
