Microsoft Releases Emergency Hotpatch for Bluetooth Issues in Windows 11

On March 16, 2026, Microsoft issued an out-of-band hotpatch (KB5084897) to address a Bluetooth visibility issue affecting Windows 11 Enterprise devices running versions 25H2 and 24H2. The update resolves a bug where connected Bluetooth devices were not appearing in the Bluetooth & devices settings, which also hindered users from adding new devices. This hotpatch is part of a series of rapid updates, following another hotpatch released on March 13 to fix critical vulnerabilities in the Windows Routing and Remote Access Service (RRAS). The Bluetooth issue affects users who rely on wireless peripherals for connectivity, and the hotpatch installs automatically without requiring a system reboot. Microsoft has not provided a timeline for a standard update to address this issue. The frequency of these out-of-band updates raises concerns about the stability of recent Windows updates.
