Interesting, thanks for this insight. I wonder how many other people are experiencing CTDs, slowness, or stuttering, and don’t realize the problem is Windows updating in the background. Unfortunately with Windows 10/11, it doesn’t seem you can easily change the setting, disabling Windows Updates like you could in previous versions of Windows.
I found this article that explains how to go into the registry and modify the default settings, setting automatic updates to notify instead of automatic install.
