I feel like this would also solve the "I just need the printer driver file(s), not everything else" use-case. Nice work.
I would also like to promote one of my most favorite tools ever: InstallWatch Pro by Epsilon Squared
It takes a complete HDD and Registry snapshot, you install something then it takes another snapshot and shows you the diff in a easy to read format.
I wish there was an equivalent for MacOS & Linux as the scripts I have tried to make(or had ChatGPT try to make) just don't cut the mustard. I'd rather just have some commercial software do this even if I have to pay for a license.
