Welcome to WebmasterWorld melba1.

Windows native backup has never been a full system backup per se. If you really wanted to revert to a snapshot in the past then you would need to take image backups with a 3rd party software. An image of your drive would allow a complete reversion to the previous state of the system.

A Windows backup is a selective file backup and will not allow a full reversion to a previous state in most cases. Some registry changes may remain after a rollback.
