This is not quite true: I still don't see the advantage of two different "Program Files" folders (Win 7/64) over a single one (XP). Quite the opposite: It makes installations more difficult, at least if the installation location is important to you. Also, try to change the icon of a certain standard file type in Win 7: This is simply not possible without an additional tool.
Let's continue: Try to save a preset from within a VST plug-in to C_Program Files_VSTPlugins while your DAW is running: Simply not possible, Win 7 won't allow it. You're forced to save it elsewhere due to access restrictions.
These are just a few examples, I could carry on for a while...
I'm not saying that Win 7 is generally worse than XP, but you should be very careful about calling the Windows development a progress.
I was able to do things on my 1992 Atari Falcon I will probably never be able to do on a Windows, MAC, or Linux system. There, you could simply take a complete program folder, copy it to anywhere on the hard disk and start the program from there. The Atari OS (TOS) didn't care at all. Now, go ahead and try this on a Windows system...
Not to mention that Atari used a user-friendly, icon-based desktop system when you still had to type cryptic commands into DOS systems. And last but not least the fact that NO virus could ever do any harm to an Atari OS, simply because it was burned in a hardware ROM chip and thus not accessible for viruses.
So, what you and others call progress, is not necessarily technological advancement, especially not in the case of Windows.
