If you actually go poke around the Internet you will see that people have tons of problems with Windows 10 drivers. Three examples I and people I know encountered:
1)crashing SSD drivers (the "fix" for that is to disable some power management settings for an SSD "sleep mode" which are not visible by default so you need some registry poking)
2)problems with wireless modems (in Thinkpads, fix is to disable and enable the device from time to time, of course it says the device is working correctly all the time which doesn't help)
3)crashes after updating from Windows 7, apparently some permissions don't update correctly and part of the system assumes it should have some permissions but it doesn't and the system crash (fix for that is apparently doing a clean install), this is bad because it doesn't even write anything to event log for some time before the crash
You can easily find tons of people talking about those problems if you google. That are only driver/system problems, there is also huge mess with forced updates which you don't have enough control over. For example if Windows 10 decides to update you can't shut down the system anymore so if you need the computer now and it freezes you need to wait till updates complete (it's easy to imagine how it's not acceptable when you want to do a presentation, a quick fix or react to something before leaving home).
Windows is 10 is huge mess and people having problems with it are definitely not outliers.
