The Prevent restoring previous versions from backups machine setting should be configured correctly. This setting lets you suppress the Restore button in the previous versions property page when the user has selected a previous version of a local file, in which the previous version is stored on a backup. If this setting is enabled, then the Restore button will be disabled when the user selects a previous version corresponding to a backup. If this setting is disabled, then the Restore button will remain active for a previous version corresponding to a backup. If the user clicks the Restore button, then Windows will attempt to restore the file from the backup media. If this setting is not configured, it will default to disabled - the Restore button will be active when the previous version is of a local file and stored on the backup. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Explorer\Previous Versions\Prevent restoring previous versions from backups (2) KEY: HKLM\Software\Policies\Microsoft\PreviousVersions\DisableBackupRestore
