@NanoRaptor On my computer I have a folder called 'Installed' and in that folder are the installation files for every piece of installed software. I replace them as they update. Also in that folder is a file called 'Licenses', which (as the name implies) contain the updated licenses for all the software.
My computer is backed up to an external drive and the external drives are backed up.
Starting from scratch: install Windows. Copy Installed folder from backup drive and re-install software. Run backup software and restore data. I could simply restore eveything from the backup drive, but reinstalling makes me ask, "Do I still use this?" 🤔
