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?

I got firmware updates this morning as well. I'm not in the Insiders program and I'm running 1903. I've set my nVidia preferences back to adaptive and have been testing all morning and it seems to have fixed the issue and the computer feels very snappy. I worried though that it had bricked my computer when installing.
Prior to this, my SB2 15" has been hanging at boot at the windows logo about 50% of the time whenever I reboot. I have to hold the power button to get it to restart. When it installed the firmware, it hung multiple times and even when into system recovery and failed to restart after that as well. I was looking on my other PC for a support phone number when it finally came up.
So far, I have not been able to crash the dGPU and I have done two reboots without it getting stuck. Fingers crossed on this one! Here's a screen shot of my driver updates. The failed installs are due to not having enough battery (40% required even if plugged in).

are you able to charge the battery and successfully install these updates or
not?
Yes. The failed attempts were from the first time I tried with 20% and the second time was 20% + plugged in. I waited until it was 40% and performed the updates. That is when I had the issues hanging on boot and feared it had bricked my box but it finally came up. That screen shot is how it appears now having done several update checks and it says everything is now installed.
