I think the right option for you would be to do a repair upgrade to correct this issue as it looks like your some of your system files have become corrupted. (This is not Reset or Reinstall of Windows). Repair upgrade fixes all Windows errors and retains all files, applications and settings. (You will not lose any data while backup is a good idea) Below is a good guide to perform repair upgrade
