Windows 10 Updates

Some update of Windows 10 may sometimes create instabilities. We recommend running diagnostic tools provided with Windows to detect any potential errors in the system.

We recommend running the Deployment Image Servicing and Management (DISM) and the System File Checker (SFC) tool. DISM is useful to recover the replacement files needed by SFC in order to fix corrupted or missing system files.

Running DISM :

  1. Open the Start menu
  2. Search for Command Prompt
  3. Right click on the result and choose "Run as Administrator"
  4. Type the following command : DISM /Online /Cleanup-Image /RestoreHealth
  5. Press Enter

Running SFC :

  1. Open the Start menu
  2. Search for Command Prompt
  3. Right click on the result and choose "Run as Administrator"
  4. Type the following command : sfc /scannow
  5. Press Enter

Restart your computer after both commands to apply updates.
