.Net Framework 3.5 (includes .Net 2.0 and 3.0) is already off when I accessed the menu. I'm using .Net Framework 4.8, which has WCF services and TCP Port Sharing on. Whatever those are.
BTW, I'm using Windows 10 but I came here because I saw that there a similar issue with Win11 and hoped that I can find a solution.
Also, there was a time (around mid-April) when "Asus Core SDK" in Armoury Crate couldn't install updates and the proposed fix for that was to install an Aura Wallpaper which forces an update, which worked when I tried at the end of April. Could that be a factor? Because the timing is just too coincidental as my Windows update problems started in May. It doesn't help that there apparently a fix for that in May, meaning that all I really had to do was wait.
