Got Bluetooth problems in Window 10? KB4505903 update could be to blame

Windows 10 May 2019 Update users have been hit by a bug brought in by the latest cumulative update which is causing Bluetooth speakers not to work. The update is optional which means it won't automatically get installed unless users manually allow it to. You may find that you're not able to connect your Bluetooth speaker, or that audio quality is awful.

A Bluetooth speaker can't connect to the computer.

Presumably Microsoft is currently fixing this issue, but for now, there's a workaround detailed in the support document. However, the sound is generated by the internal speaker instead of the Bluetooth device. A new support doc by Microsoft outlines the Bluetooth functionality issues users are experiencing with the Windows 10 KB4505903 update on their PC.

Affected May 2019 Update users need to fire up the System File Checker tool and use that to fix missing/corrupted files, which is evidently the issue here following the cumulative update. Once the process concludes, restart your PC.

Note It may take several minutes for the command operation to be completed.

This is not the first time Windows 10 users have experienced issues with Bluetooth connectivity.

Microsoft is still now blocking some Windows devices with compatibility issues after receiving the May 2019 Feature Update, in an attempt to prevent users of incompatible computers from experiencing degraded performance after upgrading.

Since then, however, more issues have surfaced.

"These security updates address a security vulnerability by intentionally preventing connections from Windows to unsecure Bluetooth devices", Microsoft had said at the time.
