I might be downvoted since this is just a random anecdote, but at work I've seen a lot of computers having a specific performance issue on Windows 8. The symptoms were Task Manager showing disk usage at or near 100% with the total throughput being around 2 MB/s on an otherwise idle system. The files being accessed were the swap file (although the system had enough free memory) and sometime Office Click to Run stuff. It also happens when the system is not idle, so it's not a random background job. I thought it was fixed in Windows 10, but I've just seen it happen on a low-end laptop. My theory is that so many developers have SSDs now and almost nobody tests on an HDD. That $300 laptop feels unusable, much worse than Windows 7 has ever felt. This issue has been reported in many places (e.g. https://www.drivereasy.com/knowledge/fix-100-disk-usage-in-task-manager-improve-pc-performance-on-windows-10/ https://www.drivereasy.com/knowledge/fix-100-disk-usage-in-t...), but most of those solutions don't work. The other thing that bugs me is the start menu search sometimes not working. Anyway, my point was that between the Windows and Office telemetry (the latter nobody mentions), random Store apps getting installed automatically and long-standing issues such as these, there are other valid reasons to dislike Windows 8/10 than "fear of change".
