A stable Windows update is a rare discovery in the world. Meanwhile, the latest Windows update, which brings a considerable number of security solutions, has a problem that can break your old Bluetooth devices.

The June 2019 Windows Update was broadcast by Microsoft and focused on improving security. Microsoft has quietly released a new support document announcing that the latest growing update to Windows 10 could break your Bluetooth devices as they get older. Windows Latest found this document and broke the news.

“You may experience problems connecting, connecting or using certain Bluetooth devices after installing security updates released on June 11, 2019. These security updates address security vulnerabilities by deliberately blocking connections from Windows to insecure Bluetooth devices. Any device that uses well-known keys to encrypt connections can be affected, including certain security fobs, “Microsoft wrote in its support document.

Users can go to ‘Event Log’ to see if their device has been affected by this problem. The event log will display an error message stating that “Your Bluetooth device has attempted to establish a debug connection. Windows does not allow Bluetooth stack debug connection when it is not in debug mode.” You can also update your Bluetooth devices to avoid this problem.

In addition, Microsoft wants users to contact their Bluetooth device manufacturer for further assistance if the problem persists.
