Key notes

We’ve recently been talking about a lot of Microsoft-designed updates for their plethora of products, but about Windows 10 and Windows 11 in particular.

If we’re talking about Windows 11, we can remind you ofKB5015882, PreviewBuild 25163, orKB5015888, which have all been released recently to the Dev, Beta, and Stable channels of the OS.

Circling back to Windows 10, the last build we presented to you was the most recent Release Preview Channel rollout, in the form ofBuild 19044.1862.

It’s time to leave all that in the past now, as Microsoft just released a brand new cumulative update for Windows 10, one that comes with some much-needed fixes.

Let’s take a deeper dive and see exactly what Redmond developers managed to fix and break at the same time through this latest patch.

What’s new in KB5015878?

What’s new in KB5015878?

We’re talking aboutKB5015878, which first of all gives you the option to receive important notifications when focus assist is on.

You might already know what Focus Assist is, and if not we’ll just tell you. It works like a do not disturb mode that hides notifications.

Furthermore, this update restores functionality for Windows Autopilot deployment scenarios that are affected by the security mitigation for hardware reuse.

KB5015878 removes the one-time use restriction for self-deploying mode (SDM) and pre-provisioning (PP) and also re-enables any User Principal Name (UPN) display in user-driven mode (UDM) deployments for approved manufacturers.

Known issues

As you can see, Microsoft manages to break a lot of stuff while fixing other problems, but that’s no longer news to anyone.

By far, the biggest achievement of this update is the fix of the dreaded DX12 problem, for which gamers will surely be most thankful for.

If you are looking to get this update, you can obtain it through theMicrosoft Update Catalogand install it directly on your PC.

That is if you haven’t already received the option to install it via the Windows Update tool on your device, which is less likely.

We’re going to keep an eye out for future updates as well and present them to you as soon as the Redmond tech giant puts them put.

Remember to only download Windows updates directly from Microsoft and not from other sources, as that might lead to your system becoming compromised.
