A lot of these issues may have to do with very outdated drivers or other unupdated software. WiFi, LAN, and audio drivers are very often overlooked and may be a couple of years old. Same with software, so many people don't update once installed, or have a bunch of crap software they don't need running that they think they do.
Windows 11 users are reporting crashes, freezes, BSODs, and failed installs after KB5079473, but Microsoft still lists no known issues for the March 2026 update.
