Microsoft got themselves into this mess and only have themselves to blame. Windows 8 was a decidedly half-baked release. Even the biggest fan of TIFKAM has to admit that the shutdown process for example was ridiculously convoluted and the whole interface was very immature.
This has meant MS scrabbling to release updated versions to fix Windows 8's shortcomings, and now MS is stuck in the hole of either supporting multiple versions of its OS, or discontinuing support for them. If they'd bothered to ensure that TIFKAM was properly implemented in the first place, they wouldn't have this issue.
And of course, a lot of Windows 8's problems from a perception point of view are down to the "stick" approach that MS used to push TIFKAM. They wanted in on mobile, so they made a deliberate decision to try and *force* it onto everyone. They went out of their way to disable registry hacks for beta versions of Windows 8 that re-enabled the start menu and decided that hitting with the stick was the right approach. You WILL use our new, convoluted and immature interface whether you like it or not.
Call me picky, but if there's one thing I DETEST, it's a company dictating to me exactly how I should use their products, exactly how I must use their interface, etc, all to try and drive that company into markets which do not concern me. The result is a deep personal hatred for Windows 8. Not just from a technical/interface point of view, but from a point of view of what it stands for.
The only thing MS can do to get around this really is to accept that Windows 8 and the stick approach has been a failure, add more options and customisability back into Windows (which they are slowly doing), and then kill off the Windows 8 brand altogether.
Like I say, all their own fault. the more you hit with the stick, the more people will resist as a matter of principle. And now with multiple versions to support or abandon, they're riling up even the adopters.
