Until Windows 10 goes end of life, (2024), it will continue to be updated.  At that point, if the system is still in use, it'll need to be upgraded to Windows11 -- or 12 -- or whatever is out by then. To block Windows 11, see [URL]  
I do NOT wish to update from Windows 10 to Windows 11. My understanding is Windows update will eventually push Windows 11 download to my computer. How can I continue to get Windows 10 security updates but never install Windows 11 in my Dell XPS 17  9700?
