Change System Protection Storage Size in Windows 10

System Restore is a feature of Windows 10 and several previous versions of Windows, going back to Windows Me. If you use the System Restore function in Windows 10 occasionally to revert your operating system to the last known stable point when it was working correctly, you might be interested in changing the maximum disk space used for system protection. As space fills up, older restore points will automatically be deleted in order to allow new points to be created.
