This will refresh Windows, after the manner of a Windows installation.
- all/most associations will be unchanged
- all your programs will be left installed

- you may need to re-establish your Wi-Fi connection
- you will need to redo Windows updates subsequent to the build you have used for the repair install
- Windows.old will be created
- system restore will be turned off- you should turn it on again and I recommend you manually schedule a daily restore point.

- inactive title bar colouring (if used) will be reset to default

This is one of the better features of Win10: as each major build comes out, that's your updated reference build, and as updates are mostly cumulative, there will be few to do.

- back up your data
- restore your system to a previously working state in a relatively short time
Recommended: Macrium Reflect (free/commercial) + boot disk/device + large enough external storage medium.
