I’ve just applied “2019-08 Cumulative Update for Windows 10 Version 1903 for x64-based Systems”, aka KB4512941 to my Microsoft Windows Surface Book 2 – after my last attempt at updating the SB2 I have become very cautious about large updates to this hardware, even avoiding updating the video drivers.
Per the release notes, I don’t see anything related to any of the issues I’ve been having (e.g. screen flickering, and the Nvidia GPU being used for 3D apps even when I set it to use that GPU in the Nvidia control panel)
There are other issues that don’t seem to be mentioned in the patch notes. I’ll update this post further if/when I get any tangible results.
I got an error that says “Please resolve before detaching” when I try to detach the screen on my Surface Book 2 using the detach button.
TLDR; When I originally posted this in 2019, the only fix was to reinstall Windows, resetting to version 10.0.18362 (Build 18362). This fixed this issue. For various reasons in January 2020 I reset the Surface again to 1909 (OS build 18363.657) and the error message about SurfaceDTX.exe is back!
Original post below…
I’m currently running Windows 10 Pro Insider Preview, version 10.0.18950 Build 18950 on my Surface Book 2. When I try to detach the tablet/screen portion from the keyboard base, I frequently encounter a series of messages that prevent the detachment to be successful.
The first error message comes up in the system tray…
Please resolve before detaching – The following may need to be closed in order to detach. Any unsaved changes will be lost – Additional User Sessions Active
I dismiss the error message by clicking the “Additional User Sessions Active”. Then, a dialog box will be displayed…
Surface DTX – Additional User Sessions Active – Someone else is still using this PC. If you continue, they could lose unsaved work.
After this, I’m prompted by User Access Control. Once I allow it, the screen will detach.
I’m going through the different logs in Event Viewer to diagnose the problem. Some quick Google searches reveal possible issues with the discreet GPU aka the “dGPU” – a thread on reddit from over ago is a dead end, too.
I’ve tried resetting the NVIDIA GPU’s settings to default, so the software will decide when and how to use the GPU.
Snappy Driver Installer still indicates that there’s a lot of potential drivers I could install, however I’m opting to only allow whatever Windows Update sends my way. SDI has been great on my desktop – it seems to cause nothing but problems with more specialized hardware like the Surface Book!
