Any Apps that write to the registry during install will need to be reinstalled with the OS anyway. And most fully compliant windows apps will install some files to the system drive regardless of where you point the installer. I went with 40 because it's so hard to resize the system partition, and doing so puts your system at risk. He could go with 20 or even 10, but if he runs out later, it's a long process to increase that partition. He has space to burn, so why not 40?

Anyways, once we move him to using image files, his reinstall/reactivate day are done. If it hoses up, blow the image back onto it. 15min tops and you’re done.
