Microsoft Fixes Windows Direct3D Issue Behind App Crashes

Microsoft has addressed a known issue causing apps using Direct3D 9 to experience problems after installing April 2022 cumulative updates, including crashes and errors on systems using certain GPUs.

The problems affect systems running Windows 11 (version 21H2) and Windows 10 (versions 20H2, 221H1, and 21H2), where users have installed the KB5012643 and KB5011831 optional preview cumulative updates.

“Windows devices using certain GPUs might have apps close unexpectedly or intermittent issues with some apps which use Direct3D 9,” Microsoft explained.

“You might also receive an error in Event Log in Windows Logs/Applications with faulting module d3d9on12.dll and exception code 0xc0000094.”

Microsoft addressed this issue via Known Issue Rollback (KIR), a Windows capability that helps revert problematic Windows non-security fixes delivered via Windows Update.

Once pushed using KIR, the fix will reach all consumer devices and non-managed business devices within up to 24 hours. However, you might be able to speed up the rollout to your systems by restarting your Windows device.

Group policies available for enterprise admins

To resolve this Direct3D issue for affected enterprise-managed devices, Windows admins have to install and configure KIR Group Policy associated with the affected system’s Windows version.

You can download the two Group Policies can be downloaded by clicking the links below:

• ​KB5012643 220509_20053 Known Issue Rollback — Windows 11
• ​KB5011831 220509_20051 Known Issue Rollback — Windows 10

The step-by-step procedure for deploying a Known Issue Rollback via Group Policy requires opening the Group Policy Editor and navigating to either Local Computer Policy or the Domain policy on your domain controller to choose the Windows version you want to use the group policy on.
