Rolling back to the previous version of Windows and System Restore is not the same; you also cannot roll back with System Restore. System Restore is used to reverse the effect of any change in settings, software update, or software installation. The Rolling back feature, on the other hand, is not always available. You can only roll back for a fixed period after installing a new version of Windows. Also, the feature works independently of System restore, and the rollback files are stored separately.
