For those who don't know exactly how this works, let me explain it.
IBM created an Operating System called OS/2 Warp. MS felt threatened. They bought the kernel code from IBM and since created something called WINDOWS NT. NT drivers were non-existent so MS threw source into the kerne for plug and playl and named it Windows 2000. 2000 was probably their largest contribution to the system kernel after IBM created it for them (sold MS the source code). Windows XP was the last version of that said source kernel purchased from IBM and butchered by MS.
MS went back to IBM and said "we need a lightweight, faster version of teh kernel that fix's X,Y, Z". IBM delivered. MS share holders where in a such a tiff that MS pre-released it before communities could create drivers for their hardware. This was called Windows VISTA. THe reason people didn't like VISTA is because most hardware wouldn't run on it. (because MS didn't give 3rd party developers time to make proper drivers). MS, again to please the share holders and OEM's, went back and butchered up the kernel. Made it a little lighter and created WINDOWS 7, which is still Windows Vista. By the time they released it, Window VISTA kernels were more abundant so people weren't as mad.
Still loosing market share from is XP dominance, MS went out hired who they thought were geniuses (people like the "Ribbon" developer who was fired after Office users revolted huge on Office 2007) and created the METRO DESKTOP. Still on, you guessed it the WINDOWS VISTA kernel. Your craptastic win 8 machine is running a kernel from around the year 2004. All MS has done is try to maintain it, which apparently they can't do.
MS can no longer buy their way into everything. Me and most of my colleagues have moved over to Linux variant (Debian here). Google has done it for their inner office and Ubuntu already uses Debian as it's "backbone". So stop waiting for a future that MS isn't going to deliver. Say goodbye to Microsoft products. You won't regret it.
