As a matter of routine, check your disk e.g. using HD Tune, and if ok run chkdsk c: /scan from an admin command or Powershell prompt as things are breaking on your system.
Then, just to be cautious, make sure you have a current disk image (Macrium Reflect e.g.)
Note that the act of creating a disk image checks the integrity of the used disk surface.
Once you have completed the in-place repair and checked things, create a new base disk image to consolidate your position.
Note that an in-place upgrade repair will not fix things specific to a user profile.
