Microsoft has released July's preview update for shipping modern supported versions of Windows 10, and it brings a few fixes. The fixes cover issues with DirectX12, XAudio API, the search box, and so much more.
Here's what you need to know if you opt to install KB5015878 (OS Builds 19042.1865, 19043.1865, and 19044.1865.) This is for Windows 10 21H2, Windows 10 21H1, and Windows Server version 20H2, respectively.
The big fix in this update relates to addressing an issue that might cause consecutive video clip playback to fail in games that use DX12. Also fixed is an issue that affects certain games that use the XAudio API to play sound effects. The third big fix covers the search box. Microsoft addressed an issue that affects the height of the Search box when you use multiple monitors that have different resolutions. The other changes in this release can be seen below.
- New! Gives you the option to receive important notifications when focus assist is on. Focus assist is like a do not disturb mode that hides notifications.
- New! Restores functionality for Windows Autopilot deployment scenarios that are affected by the security mitigation for hardware reuse. This update removes the one-time use restriction for self-deploying mode (SDM) and pre-provisioning (PP). This update also re-enables any User Principal Name (UPN) display in user-driven mode (UDM) deployments for approved manufacturers.
- Addresses an issue that prevents certain troubleshooting tools from opening.
- Addresses an issue that causes certain docking stations to lose internet connectivity when waking from Sleep mode.
