Quote:“Microsoft has identified compatibility issues with some driver versions for Bluetooth radios made by Realtek and Qualcomm,” the company briefly says.
 
A workaround already exists, but in the meantime, Microsoft says it has set an upgrade block for these devices in order to make sure the issue doesn’t become widespread. In other words, if your device is prone to the Bluetooth bug, it won’t be offered the May 2019 Update on Windows Update to prevent the glitch.
 
“To safeguard your update experience, we have applied a compatibility hold on devices with affected driver versions for Realtek or Qualcomm Bluetooth radios from being offered Windows 10, version 1903 or Windows Server, version 1903 until the driver has been updated,” Microsoft says.
