  • press WIN + X and select “PowerShell (administrator)” from the list;
  • paste the sfc /scannow command into the console and press ENTER;
  • read the results of the SFC and restart the PC;
  • open PowerShell again (as admin!) and execute the following commands in the console one by one:
    • DISM /Online /Cleanup-Image /CheckHealth
    • DISM /Online /Cleanup-Image /ScanHealth
    • DISM /Online /Cleanup-Image /RestoreHealth
