Hi, just recently installed the Windows 10 May update on my Surface Book 2. Now the GPU disappears randomly while in use. The only solution is to reboot the Surface Book 2, or go into the device manager and initiate a scan for the GPU to come back again. It has Nvidia Gforce GTX 1050 version 23.21.13.9140
Are there any plans for Microsoft to release an updated driver to fix this bug?

2019-10-28T13:47:54+00:00 The only thing I noticed is some blackouts of the screen after boot requiring to press power again and them it stays fine... Minor flaws that were on previous version as well
The good part is that it seems there is no SurfaceBook3 on horizon so MS will have to address those issues because the machine will take longer to be replaced by a newer model....

Don't think so; I have replicated on multiple SB2 devices, of which were examined and tested by Microsoft before shipping to me.

2019-11-16T16:10:02+00:00 Throttle is NOT fixed. I tested with SB2 docked with Surface Dock, lid closed, almost immediately greeted with .4GHz throttle. Running latest drivers/firmware from about a month ago that supposedly fixed the throttle. As soon as I opened the lid, fans came on full force, cooled the SB2, and throttle was lifted once it cooled.
