Microsoft issued an out-of-band update for a recent Windows 11 patch after it caused multiple regressions, including Remote Desktop Services instability that could disrupt connections and sign-ins. The emergency update also addresses audio input and output failures and a problem that prevented Claude Cowork from working with HC-managed Linux virtual machines using Plan9 shared folders. Reports of AMD Radeon crashes, Explorer black screens and other hardware-specific issues remain in the supplied account.
