That sucks ! Microsoft did this things better in the past. Or they just want people getting new Win versions.
Oh god, no they didn't

This has been the case since as far back as I can remember

Have DirectX 9? well, guess what, you still need Directx 5 and 6. Have .Net 4.5? well, you need 1.0 and 2.0 as well.
Not saying other companies are any better (Apple :cough:) but Windows has always been a nightmare for running software compiled for older runtimes, if you have to start from fresh without having to hunt for multiple versions of supposedly the same thing.
