I mostly use Linux but need Windows for some applications. I have been a user of Windows since 3.1 and long admired the Company. This release has bothered me because of the spyware. Google for "Windows 10 spyware" for some discussions. I will stay on Windows 7 to the extent possible, but they are putting out Windows 7 updates with some of that same spyware and disguising them so you can not tell what you are installing. Researching more knowledgeable peoples findings and declining the update only results in them issuing new ones. Decline all the information gathering options and it is said they still connect to ports on their server and send information. I have stopped installing updates, I may go back and just install the security ones but am at the point of not trusting them anymore. Might look into how a business version of Windows 7 is treated perhaps they don't do it there, I wouldn't think other Corporations would be too thrilled with them spooling data off their systems.
