If an application calls the CreateRestorePoint method to create a restore point, Windows skips creating this new restore point if any restore points have been created in the last 24 hours. The CreateRestorePoint method returns S_OK.

Developers can write applications that create the DWORD value SystemRestorePointCreationFrequency under the registry key HKLM\Software\Microsoft\Windows NT\CurrentVersion\SystemRestore. The value of this registry key can change the frequency of restore point creation. The value of this registry key can change the frequency of restore point creation. If the application calls CreateRestorePoint to create a restore point, and the registry key value is 0, system restore does not skip creating the new restore point. If the application calls CreateRestorePoint to create a restore point, and the registry key value is the integer N, system restore skips creating a new restore point if any restore points were created in the previous N minutes.
