Windows 10 updates have become a game of chance. You almost never know when an update will break something and make your PC unusable. Although Microsoft is trying to fix things after the fact, often the damage is already done. Now, Microsoft is taking the initiative to warn users that an upcoming update could result in the loss of connection of Bluetooth devices to Windows computers. And no, it's not a bug, but a feature.
The updates seemed pretty innocuous. They contained the usual bug fixes, including security patches for known vulnerabilities. One of these, however, is the flaw described in CVE-2019-2102, which states that low-power Bluetooth connections can be used to remotely send arbitrary keystrokes, all without any interference from the user. ;user.
The cumulative Windows 10 updates dated June 11, 2019 and later correct this problem, but have a rather annoying side effect. According to Microsoft's own bulletin, reputable unsecured Bluetooth devices will not be able to connect to Windows 10. There is no specific device class assigned and Microsoft even mentions keychains as potential candidates.
Unfortunately for users, the only way Microsoft can give them is to tell them to contact their Bluetooth device provider. To be fair, there is no choice but to close this security breach so as not to risk exposing Windows users. This does not make it less convenient for them though.
Users could perhaps wait for the installation of said updates, but it also opens a different Pandora box. On the one hand, users will not know which devices are affected until the update is applied. Equally important, not installing these updates could also make them vulnerable to other bugs.
