GoKawiilMicrosoft has released an emergency update to fix a Bluetooth device visibility issue on hotpatch-enabled Windows 11 Enterprise devices.
The Bluetooth devices will not appear in Windows Settings or Quick Settings, even though they're functioning correctly and connected to affected systems.
This bug could also prevent some users from adding new Bluetooth devices because available devices will not appear in the connection list.
The out-of-band (OOB) KB5084897 hotpatch was released on Monday for systems running Windows 11 versions 25H2 and 24H2 and will install automatically without requiring a restart.
"Microsoft has identified an issue affecting hotpatch-enabled Enterprise editions of Windows where Bluetooth devices may not appear on the Bluetooth & devices page in Windows Settings or in Quick Settings, even though the devices are connected and functioning as expected," Microsoft explained.
"In addition, users might be unable to add Bluetooth devices because available devices do not appear in the connection list."
This OOB cumulative update includes all improvements and security patches that shipped with the March 2026 Windows hotpatch updates and will not install on Enterprise devices that receive standard Windows updates.
On Friday, Microsoft pushed another Windows 11 Enterprise OOB hotpatch (KB5084597) to patch three high-severity vulnerabilities in the Windows Routing and Remote Access Service (RRAS) management tool, which could allow attackers to execute malicious code remotely when connecting to a malicious server.
"An attacker authenticated on the domain could exploit this vulnerability by tricking a domain-joined user into sending a request to a malicious server via the Routing and Remote Access Service (RRAS) Snap-in," the company noted in advisories issued last week.
"This issue only applies to a limited set of scenarios involving Enterprise client devices running hotpatch updates and being used for remote server management."
