... I used to repair/reset PC's for a living and the number of times I heard "I never touched it. I woke up this morning and turned it on and that was all!!" Knowing full well the behaviour of the PC could ONLY have been casued by human intervention hahaha!
All I know is (and having been - necessarily - a tweaker with W7, W8 and most previous versions) W10 is such a joy to work with.
The only times i had problems with Windows 10 was after some "as necessary announced update" (Fred Blogs?) had secretly turned on windows update in services. Besides i have 3 bought Win 10 pro licenses (obtained via the updating schemes from Win 8.1 and 7) that worked for a while, and then all of a sudden the activation seems invalid. Checking things with microsuck (yeah, i know, and shut up) online and by calling them, gave me some Illiterate Indian guy who wanted TeamVieuw let loose on my PC; my foot.
BTW The same goes for Office 2016. Last year i bought a legit download (online) installer version, and after a while it just won't run claiming that there was some activation problem. Reinstalled Office 2010 with some updates; seems to work for now, but still i feel i was lured by some MS marketing scheme in spending money unnecessary.
IMO you cannot survive with Win10 on a PC without something like KMS activator, "takeownership", Tweaking.com's Windows repair, CCleaner, and tweaking tools like 00SU10 and Win10privacy, to keep windows 10 simple and healthy. Also some 3rd party Firewall is a must, besides SpybotSD and Malwarebytes, and a proper (bought) viruskiller. Setup properly Win10 it's quite a bit "better" than XP, 8.1, and even Win7. And, no creators for me yet ... F
