Create a restore point before a risky change

Roll back easily after a driver or program causes trouble.

1. Open "Create a restore point" from Windows search.
2. Select drive C: then "Configure" and turn on system protection (a few GB is enough).
3. Click "Create", give it a clear name (e.g. "Before graphics driver") and confirm.
4. The same in administrator PowerShell:

   Checkpoint-Computer -Description "Avant installation" -RestorePointType MODIFY_SETTINGS

   Copy
5. To roll back: "System Restore" in the same window, then choose the point.
