First, why is it someone else's responsibility to do an end user's research for them? If an end user doesn't want to research their own issues, there are places and services they can pay to have them do it for the end user. Considering this forum offers a way to search this thread, in combination with the ability to easily see a specific user's posts, asking an end user to do so is not rude... it's called having personal responsibility.
Second, the prior user's issue, and most others', is not a Windows 10 issue, it is a drivers issue. Windows 10 works fine, albeit there are a few bugs, most of which are environment specific and, again, due to drivers. Drivers are completely separate from Windows, regardless of version, and it is not, nor should it be, Microsoft's job to ensure users don't have issues with the drivers.... that responsibility lies solely with the component manufacturers.
Third, an end user refusing to do the most basic form of research posts to this thread, and many others, on a daily basis. If an end user doesn't want to be told bluntly that it's their computer and to have personal responsibility, then they can avoid it altogether by having personal responsibility.
I understand many, if not most, are not power users, just as I understand the blind keep trying to lead the blind when it comes to Windows 10. There is only 1 reason for the need to upgrade to Windows 10, of which is so your motherboard's hardware ID can be registered with Microsoft so the end user can receive their free upgrade. Once upgraded, an end user should perform a clean install, especially if using a PC manufactured prior to July 2014. It is not anyone's responsibility, but the end user's, to research the proper way to install an OS, and the failure of end users to do so is the cause of 90%+ of the issues experienced with Windows 10.
Even with all of that being said, I'm always more than happy to help someone; however, after responding to more than 50 posts on this thread and others stating the same thing over, and over, and over again it becomes irksome. I don't believe anyone finds repeating themselves more than three times as pleasant and not irritating or frustrating... especially when most users never bother to read 10 posts back from the last post, and is insanely frustrating when not more than a few posts back one can find the same information they're asking about.
