I am running a barebones version of Win10 LTSC with everything unnecessary ripped out. Security updates, especially those written by Microsoft pajeets, are fucking worthless and never provided any protection in the first place; it's a marketing gimmick and fearmongering to get people to switch to 11. Windows has always been a piss-easy system to crack, so it's not like your updates can actually stop anyone who knows their shit from getting access.
I keep all important files and data on separate drives that I only connect in case of necessity. There is nothing of worth on my PC proper, and I just sweep it with Malwarebytes once in a while.
Once Win10 is completely unable to support new software, much like Win7 today, I will switch to Mint. Or maybe SteamOS, which is essentially the same.
Fite me.
