Windows 10: OpenGL app crashes on headless system after Windows update

I have an OpenGL application that worked without any problems as Windows service launched under SYSTEM on a headless server. OS: Windows 10 Pro, Card: NVIDIA GTX 2080. But after update of Windows 8th September update the same application crashes when I try to work with OpenGL calls. After Windows update it showed such information in a log about available version of OpenGL: OpenGL 0.0 Vendor: Microsoft Corporation Renderer: GDI Generic But before update it showed that version was 4.6 and vendor NVIDIA nothing else was changed. Updating NVIDIA driver to the latest 452.06 WHQL did not solve the problem. Only Windows restore helped. The problem Windows update:https://support.microsoft.com/en-us/help/4571756/windows-10-update-kb4571756


Why after Windows update only MS version of OpenGL is available for a service such version is not suitable for my application?

Windows Update breaks OpenGL support for SYSTEM-User

Hi,

one of my applications is running as a service started from the SYSTEM-user and was using OpenGL before without any problems. No I have problems on machines that have Windows Version 1903 - A regular Deskop User gets an opengl-context without any problems,
but the SYSTEM-user only gets opengl version 1.1.

Is there any workaround for this problem?

I already tried the following:

• Reinstall drivers
• Purge and reinstall driver
• Set "interactive" flag for windows service

Monitor is attached and a user is logged in.

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.
