  • This cmdlet uses the CreateRestorePoint method of the SystemRestore class with a BEGIN_SYSTEM_CHANGE event.

  • Beginning in Windows 8, Checkpoint-Computer cannot create more than one system restore point each day. If you try to create a new restore point before the 24-hour period has elapsed, Windows PowerShell generates the following error:

    "A new system restore point cannot be created because one has already been created within the past 24 hours. Please try again later."
