Hi. I'm an owner of a BT3 Pro. After the update of Windows 10 1803 (the April 2018 update), my PC starts to have problems, like the Start Menu not working. I restored the OS with the Media Creation Tools provided by Microsoft and I have resolved the problem, but after that I noticed some laggy performance of the gpu and on the system. What can I do? Where I can find the download for BT3 Pro's OS and drivers?
