Sony Vaio: Bluetooth not working after Windows update

October 2016


I have a Sony Vaio laptop with Windows 7 64-bit. After the automatic installation of several updates for Windows 7, the Bluetooth feature is no longer working.


  • Click on Start > in the search field type "bttray"
  • Right-click> Properties > Compatibility.
  • Run this program in compatibility mode for "Windows Vista"
  • Repeat the operation for "BTStack Server"

Thanks to Cam for this tip.
