The Windows 10 update purposely interrupts some Bluetooth connections

Windows 10 updates have become a game of chance. You almost never know when an update breaks something and makes your PC unusable. Although Microsoft tries to fix the problems later, the damage is often already done. Now Microsoft is taking the initiative to warn users that an upcoming update may cause Bluetooth devices to lose their connection to Windows PCs. And no, it's not a mistake, it's a function.

The updates seemed harmless enough. They included the usual bug fixes, including security fixes for known vulnerabilities. One of them, however, is the one described in CVE-2019-2102, where Bluetooth Low Energy connections can be used to remotely send arbitrary keystrokes without the user having to intervene.

Unfortunately, Microsoft users can only be asked to contact the manufacturer of their Bluetooth device. To be fair, there is no alternative but to close this vulnerability or run the risk of endangering Windows users. However, this does not make it any less convenient for you.

Users may be able to interrupt the installation of updates, but this may open another can of worms. For one thing, users only know which devices are affected after the update has been installed. It is equally important that these updates are not installed and therefore prone to other errors.
