After turning on the protection, we uninstalled some programs, removed some files, and cleaned up the hard drive. We removed as much as 3 GB of data.
Then we turned off the machine, turned it on again, and chose restore in the menu.
And ta-da, or rather after about 4 minutes of waiting for Windows to start, the machine was exactly the same as before we did the “clean-up”.
Just as amazing every time.
