Microsoft is blocking the Windows 10 November 2019 Update on systems with certain Realtek Bluetooth drivers

Windows 10 boxes

Some drivers for Realtek Bluetooth radios are casing compatibility issues with Windows 10 November 2019 Update, leading Microsoft to block the update on affected systems.

Anyone with an outdated version of the Realtek Bluetooth driver will be greeted by a message informing them: "Realtek Bluetooth: Your PC has a driver or service that isn't ready for this version of Windows 10". Updating Windows 10 to the latest version is blocked until users follow the steps set out by Microsoft.

In an online help document Microsoft explains that it has "identified compatibility issues with some driver versions for Bluetooth radios made by Realtek". The company goes on to explain: "You will need to update to driver version 1.5.1012 or later to remove this safeguard hold.  Any earlier version of the driver is affected by this issue".

This is the same issue that previously affected people trying to install the Windows 10 May 2019 Feature Update (Windows 10, version 1903) and Windows 10 October 2018 Update (Windows 10, version 1809). The easiest solution is to simply check Windows Update for newer version of the Bluetooth drivers before trying to update Windows 10 itself, but this may not work for everyone.

Microsoft also provides fairly lengthy instructions for manually updating drivers if, for some reason, it is not possible to automatically update them:
