A stable Windows update is a rare finding on earth. Meanwhile, the latest Windows update, which is bringing in a considerable number of security fixes, has an issue which could break your outdated Bluetooth devices.
The June 2019 Windows update has been aired by Microsoft and is hugely focused on security improvements. Microsoft quietly published a new support document to announce that Windows 10’s latest cumulative update could break your Bluetooth devices if they are outdated. Windows latest was the first to spot this document and break the news.
“You may experience issues pairing, connecting or using certain Bluetooth devices after installing security updates released June 11, 2019. These security updates address a security vulnerability by intentionally preventing connections from Windows to unsecure Bluetooth devices. Any device using well-known keys to encrypt connections may be affected, including certain security fobs,” Microsoft wrote in its support document.
Users can head over to the ‘Event log’ to know if their device is affected by this issue. The Event Log will display an error message saying, “Your Bluetooth device attempted to establish a debug connection. The Windows Bluetooth stack does not allow debug connection while it is not in the debug mode.” You could also update your Bluetooth devices to avoid facing this issue.
Additionally, Microsoft wants users to contact their Bluetooth device manufacturer for further assistance if the problem persists.
The following latest cumulative updates (LCUs) and Monthly Rollups released on June 11, 2019 or later for the affected platforms will experience the new behavior:
The following Security Only updates are also affected:
KB4503290 for Windows 8.1 and Windows Server 2012 R2.
KB4503263 for Windows Server 2012 and Windows Embedded 8 Standard.
