Microsoft confirms that the latest cumulative update has caused Windows 8/10 to fail to connect to Bluetooth devices properly

Microsoft has confirmed in the Windows 10 update log that the latest released cumulative update may affect the normal connection of some older Bluetooth devices.

Microsoft said that this problem must be fixed by the Bluetooth device manufacturer to launch a new version of the driver, users and Microsoft cannot solve this problem unilaterally.

When starting the Bluetooth device, look for the BTHUSB or BTHMINI related logs in the Windows Log of the Event Viewer – System and check the details. If the log shows content like the following, you must update the Bluetooth driver to solve the problem. You can check the event viewer by yourself.
