Win10 is very much a dog that has not been housebroken. I have seen it take over a "sleeping" machine and forcibly do an update, when updates had been postponed and NOT asked for. And the updates repeatedly broke power options on a laptop, i.e. sleep/wake on lid close/open, disabling the Fn+F4 power functions, and disabling a "special" programmable keyboard button. All without any notice to the user, all without any indication in the online materials.
I've also seen Win10 force the choice of default applications, i.e. using Edge instead of any other browser, using Acrobat's online "lite" version (with all the optional purchases) instead of a prior fully licensed version of Acrobat, etc. In each case, yes, you could puzzle out how to find the menus to choose and set default programs to handle application types--but Win10 simply presented those menus while LOCKING the choice of programs, so they could not be used.
It has some nasty quirks, there are good reasons that a happy Win7 or even Vista user would not want to move to it. The sole benefits to Win10 appear to be in the alleged security improvements. Which are of course not visible to consumers, and then the Edge browser is supposed to have some security issues that third-party browsers quickly addressed, but MS did not. Or could not.
No OS is perfect. MS doesn't even present a feedback mechanism for users to report these kind of bugs, other than the online forums, where alternative facts (thank you, Kelly Ann) are rampant and facts or official presence rarely to be found.
