Microsoft released a September Patch Tuesday update for Windows 11 that addressed nearly 1,000 vulnerabilities but introduced bugs affecting some users' PCs. The update, 25H2, reintroduced features like a movable taskbar and a customizable Start menu. Users with AMD Radeon GPUs reported system crashes due to driver instability, and emergency patches from Microsoft did not resolve these GPU issues. Users are advised to consider rolling back their systems to a state prior to the August Patch Tuesday. HP and Lenovo PC users are cautioned, as the update may cause BIOS corruption on HP machines and random shutdowns or black screens on Lenovo devices. HP is working on a BIOS revision, but the cause of the issues remains unclear.
