Continuous Background Video Encoding & Capture Thread Hooking

When Game DVR background capture is active, Windows constantly records your screen in a rolling buffer, stealing GPU encoder bandwidth and disk I/O.

Even when users think background recording is off, GameBarPresenceWriter.exe injects background capture hooks into every launched game binary. This introduces frametime spikes and adds up to 3ms of input lag. We safely disable Game DVR and background capture hooks via registry policies while keeping Game Pass logins and Xbox party voice chat 100% operational.
