Im pretty sure backup points are for rolling back registry changes and the like. A proper snapshot would be too unweildy.
I just cram all the installation programs I want to run at OS install onto an network HDD then my server has a network script that handles the reinstalls for me. Still takes eternity to upgrade windows after its on but it can be unattended overnight kinda thing, once its done with the OS the script plows through the msi's and exes on the external.
Linux is even easier, you dont need the external drive, just an internet connection and the right bash script, the other beauty is that if you partition the /home directory right then upgrading/reinstalling the OS doesnt touch any of your personal files and settings so once the software is back on its even set up the way it was before you began.
