There are reasons why many people have not transitioned to Windows 10. Two major ones are that many people have not forgotten Windows ME and Windows Vista. They also still remember the Windows XP slow down as it bloated up from updates and the fact that Windows 8 was not exactly a big improvement over Windows 7. Windows 7 has provided stability which is certainly not I had with other versions. I've gone through MS-DOS and 8 versions of Windows, two of which (ME and Vista) were simply awful. Over the past few years, Microsoft has distributed Windows updates (both 7 and 10) which had major problems. Based on this history, it is hardly surprising that people are not switching from Windows 7 which works well to Windows 10.
It appears to me that Microsoft is killing off the media metadata now, because it will not upset corporate IT managers who are still on Windows 7.
