I have had W10 destroy one notepad and one computer. With the notepad, running W 8.1 10 attempted to install and failed. I called up MS and they attempted to install 10 and failed. I took a ball peen hammer to the notepad.
The other computer was an older computer my wife fell in love with and I would only be able to get her off of it an on to a newer computer would be if the computer failed. W 10 attempted to install and killed the hard disc. I could have replaced the HD, but it can be a little difficult finding an IDE HD. So, I called the computer failed. I installed 10 on a newer computer, installed Classic Shell, her back up files and photos from the NAS and she is off and running. I also updated her office suite and a few other programs she uses, found alternatives for Adobe PDF suite (Foxit Pro). With Classic Shell my wife can use the computer and she has adapted well.
My primary work computer, I removed system write permissions from several directories and locked a few select registry entries and took system privileges from those entries. I run Win 8.1 with Classic Shell as the primary OS. Inside of virtual machines I run several different OS's including OSX, BSD, Kali, Debian, and Windows 10. Once I finished locking down the computer, I took the extra step of shutting off all updates. I do not recommend shutting off updates unless you really know what you are doing because you are running a risk of infection if you do not properly lock the computer down.
When people ask, I steer them away from Windows 10. I will continue to do so until MS gets their head out of their ass and they also stop attempting to track what people do on their computers. I am afraid that I will have a long wait.
In the future I will install BSD as the primary OS an only run Windows inside of a virtual machine.
