Subject: Formal Bug Report: Recurring DXGI/D3D Regression on Dual-GPU Optimus-Disabled Configuration — KB5079473 / KB5077181 / KB5074109

Dear Microsoft Windows Engineering Team,

I am writing to formally report a reproducible and recurring regression in the DXGI/D3D11 graphics layer introduced by multiple Windows 11 Cumulative Updates (KB5074109, KB5077181, KB5079473) on a specific hardware configuration: a Dell Precision 5520 workstation running Windows 11 Pro 25H2, equipped with dual GPUs (Intel HD Graphics P630 + NVIDIA Quadro M1200 Maxwell) with Optimus disabled.

Each of the above updates has rendered the system completely unusable for professional Adobe Creative Suite workloads (Premiere Pro, Photoshop, Lightroom Classic), forcing a full system restore from backup as the only viable resolution.

I have additionally observed that KB5079473 updated the Intel HD Graphics P630 driver from version 31.0.101.2137 to 31.0.101.2140 despite the registry flag ExcludeWUDriversInQualityUpdate being set to 1, which I believe warrants separate investigation.

The attached technical report documents the full hardware configuration, a detailed chronology of each regression event, diagnostic evidence collected, and the specific questions I am asking your engineering team to investigate.

I am available to provide additional logs, memory dumps, or PowerShell diagnostic output upon request.

Thank you for your attention to this matter.

Marco

Thank you for the clarification. I have already submitted the report via Feedback Hub. I'm posting here as well to document the issue publicly and check whether other users with dual-GPU Optimus-disabled configurations are experiencing the same pattern with these updates.

Intel HD P630 driver 31.0.101.2140 pushed by Win11 CUs breaks DXGI on dual-GPU Optimus-disabled config with Maxwell GPU — reproducible 3x - Microsoft Q&A

Every Win11 Cumulative Update since January 2026 silently upgrades Intel HD Graphics P630 driver from 31.0.101.2137 to 31.0.101.2140, bypassing ExcludeWUDriversInQualityUpdate=1 registry flag. This causes a DXGI/D3D11 regression that makes the machine…

(Intel iGPU as display controller + NVIDIA Maxwell as renderer) and
has experienced DXGI crashes after recent Cumulative Updates, please
