My laptop is Win11, my desktop is Win7. While MS no longer "supports" Win7, it still updates on occasion. I have no idea what's updating but it creates a restore point when it does. I'm still able to use FireFox although I did have to transition to a version used on work group computers. I use Windows Defender on the desktop along with Malwarebytes. I'm aware that, someday, Win7 will stop working on the internet but that day isn't here yet. I have noticed that some sites are very slow on my desktop now but normal on my Win11 laptop so I'm assuming it's a scripting difference that the old system is struggling with. I did put a shell on my Win11 laptop to make it look and work (mostly) like Win7. If you're using Win10, you'll likely be OK for some time to come. I read there's a user that filed suit against MS to force them to provide support for Win10 until usage falls below 10%. I have no idea about the success, or lack of, of that suit.
