Microsoft released an out-of-band hotpatch, KB5084897, to address a Bluetooth visibility issue on Windows 11 Enterprise devices enrolled in the hotpatch update program. The update, launched on Monday, installs automatically and does not require a restart.
The problem prevents connected Bluetooth devices from appearing in Windows Settings under Bluetooth & Devices or in Quick Settings, even if they are working properly. Users affected by the bug are also unable to add new Bluetooth devices because they do not show up in the connection list.
Affected Windows 11 Enterprise Versions for KB5084897
KB5084897 is applicable to Windows 11 versions 24H2 and 25H2 on Enterprise editions with hotpatch enabled. The update won’t install on Enterprise devices that are receiving standard cumulative updates. It includes all enhancements and security patches from the March 2026 Windows hotpatch release.
Second Windows 11 Enterprise OOB Hotpatch in Three Days
This is the second out-of-band hotpatch from Microsoft for Windows 11 Enterprise in less than a week. On Friday, Microsoft released KB5084597 to address three high-severity vulnerabilities in the Windows Routing and Remote Access Service (RRAS), which could allow an attacker with domain credentials to execute malicious code by convincing a user to connect to a malicious server via the RRAS snap-in.
Hotpatch updates fix issues by applying patches directly to running processes in memory while also updating files on disk, so the patches remain effective after a reboot without requiring an immediate restart.
The KB5084897 hotpatch update was released on March 17, 2026, and is now rolling out automatically to qualified devices.
