The headline feature of KB5083631 is the *slowly rolling out* new Xbox mode, which replaces the desktop with a controller friendly screen, as when using an Xbox. The part that worries me a little is below. Microsoft is trying to tighten security around drivers, which is good since using a driver with known vulnerabilities is a favorite trick of malware -- it'll install such a driver, then use it to make sure the exploit starts early in the Windows startup process. The bad part is that some drivers will wind up being blocked -- probably less common ones from less common sources, so it may be unlikely you'll find an alternative or newer version. I'm thinking things like Bluetooth, WiFi, Touchpads, Touch screens etc., since even big brands can use parts from small, less known companies to save costs, and/or there are a ton of low cost dongles for things like WiFi & Bluetooth out there.
[Windows Driver Policy update] New! This update improves Windows security by changing how the Windows kernel trusts third‑party drivers. Default trust for cross‑signed drivers is removed, while drivers from the Windows Hardware Compatibility Program (WHCP) and an allow list of trusted legacy drivers remain allowed. Windows audits driver compatibility for at least 100 hours and three reboots before enabling enforcement. After enforcement, a small number of cross‑signed drivers might be blocked. For more information, see the Windows driver policy and the Advancing Windows driver security blog.
