If you encounter a complete system crash, or you are unable to start the Windows OS, you need to rollback the system from the Rollback Rx Subsystem Console.

1. To access the Subsystem Console, restart the computer press the HOME key as you see the RollBack Rx splash screen logo. You will need to provide a user name and password if the RollBack Rx access control is enabled.
 
2. Click on "Rollback system". You will see a list of available snapshots. Select a snapshot and click on "Next" to rollback to the snapshot.
