Summary: Use Windows PowerShell to quickly create a system restore point.
How can I use Windows PowerShell to roll back the settings if the changes I make mess up my computer?
Open the Windows PowerShell console with Admin rights, and use the Checkpoint-Computer cmdlet.
Specify a good description of the checkpoint and the restore point type, for example:
Checkpoint-Computer -Description 'everything fine' -RestorePointType modify_settings
