Dependencies should be garbage collected. It’s really simple, a counter has to be maintained somewhere, to keep track of the number of links pointing to a particular dependency. When this number reaches 0 it means that the dependency is not referenced anywhere hence there is no use for it and it can be automatically deleted. This is how it’s done in JavaScript, java, and other garbage collected environments.

This is typical of Microcrap, their installer .msi files, used my software companies, is also a waster of RAM as it duplicates sometimes more than twice and in hard disk copies itself or parts of itself to different folders, and I have checked and many of the files in WinSxS are duplicated, instead of making .ini files and make smart use of folders they could make it efficient and always working for all software, but no they had to go the cheap and dumb way and screw us all in the butt along with it these Suns of Beaches will eventually pay the consequences, as everything doe, of their own acts and It will be too late for regrets; software titan my a$$!!!
