Microsoft: Recent Windows updates may trigger Remote Desktop failures

Microsoft says recent Windows 11 updates can break Remote Desktop for non-admins when Administrator protection is enabled.

Microsoft confirmed that non-admin users may fail to connect over Remote Desktop after installing the September 2026 KB5124010 preview or later updates when Administrator protection is enabled. Affected systems include Windows 11 24H2, 25H2, 26H1 and 26H2; connections can return error 0xC000000D. The feature is enabled by default in the relevant Windows security baselines. Until a fix ships, administrators can disable Administrator protection through Intune or Group Policy.

Microsoft: Windows KB5124010 update crashes some games and apps

Microsoft says Windows 11 preview update KB5124010 crashes some games and apps that use AC-3 audio.

Microsoft confirmed that some games and applications using AC-3 Dolby Digital decoding crash after the optional September 2026 Windows 11 preview update KB5124010. Affected apps may fail to launch, close without warning, or break only when features such as music playback are used. The update installs only if users choose it, or automatically on Windows 11 24H2 when early updates are enabled. Microsoft said many modern apps are unaffected and that a fix is in progress without a published timeline.
