I haven't heard of that before. What is the purpose?
You have to understand that Microsoft is a “legal” gang. When they send out updates for their software they can also include code that will cause your “outdated” operating system to do strange things.
They’re not the only ones either. My android tablet went tee-you because some of the google updates messed up the google O/S I already had. Anytime an organization - private or government - gets so big it can dictate what you must do it is a DICTATOR in the classic sense of the word. From that point on you are working for them...for free!
