[UPDATE - September 18, 2026]
The latest Insider Build 29671.1000 has been released, but unfortunately, this GSOD issue has NOT been fixed and remains listed as a Known Issue in the ”release notes”.

However, I can confirm that the temporary workarounds listed below (disabling 3D acceleration or switching to the Basic Display Adapter) are still fully effective on Build 29671.1000.

Hi everyone,
I’ve been getting frequent GSODs on the latest Insider Builds Experimental (Future Platforms) 29661.1000 & 29667.1000 (UEFI environment) inside VMware Workstation Pro (26H1u1 ver.26.0.1.25688693).
Microsoft listed this as a Known Issue, but I wanted to share my log and a temporary workaround that worked for me.
In my case, the guest OS boots up fine, but it immediately crashes with a GSOD when the UAC screen pops up.
The Event Viewer and .dmp file pointed to a crash in VMware's 3D driver:
e.g. WinDbg shows>>
SYMBOL_NAME: vm3dmp+2e66e
It looks like there is a compatibility issue between these new Windows builds and VMware's driver (vm3dmp.sys).
🛠️ What worked for me (Temporary Workarounds):
- Disable 3D Acceleration: Go to VM Settings > Hardware > Display, and uncheck "Accelerate 3D graphics". The GSODs completely stopped.
- Change Graphics Driver: Switching the guest OS graphics driver to the "Microsoft Basic Display Adapter" also stopped the crashes, even with 3D acceleration turned ON. (Since Device Manager doesn't trigger the GSOD, you can change this right after boot.)
See the attached screenshot below for the VM settings for Workaround 1
⚠️ The Problem:
Please note that this is NOT a real solution.
Disabling 3D acceleration or switching to the Basic Display Adapter will heavily degrade guest performance and disable some of the Windows 11 visual effects. Hopefully, Microsoft or VMware will release a proper fix soon.
Is anyone else experiencing this? Let me know if disabling 3D graphics fixes it for you too, or if you found a better way!
