Microsoft Releases Windows 10 KB5015878 Update — What Does It Include?

Microsoft has recently released its Windows 10 KB5015878 update.

Microsoft's KB5015878 update is an optional cumulative update for devices running on Windows 10 21H2, Windows 10 21H1, and Windows 10 20H2.

According to BleepingComputer, the KB5015878 cumulative update preview is included in Microsoft's monthly "C" update for July 2022, allowing administrators to test anticipated changes issued in the August 2022 Patch Tuesday.

This Windows 10 update contains a slew of improvements to the system, including the Windows Autopilot fixes, as well as a new Focus Assist feature.

Furthermore, this update improves the service stack's overall quality. The servicing stack is the component that is responsible for installing Windows updates.

In order for your devices to be able to receive and install Microsoft updates, it is necessary to have a robust and dependable servicing stack.

Microsoft's Windows 10 KB5015878 Update

This Microsoft update for Windows 10 version 20H2, will unfortunately reach the end of service on August 9, 2022.

That means that devices that are running on version 20H2 will no longer receive regular security and quality upgrades that guard against the most recent security risks after August 9, 2022.

Microsoft advises updating to the most recent version of Windows Server in order to continue getting security and quality upgrades.

Furthermore, with the Windows 10 KB5015878 update, it is important to note that this update does not include any security updates. However, it does contain numerous quality improvements.

There are a plethora of improved features and fixes, and as noted by Microsoft, here are some of them:

The update enhances the dependability of a push-button reset following an OS upgrade and addresses issues that were causing port mapping conflicts for containers.

It solves a problem that had been preventing certain diagnostic tools from starting up properly before.

It fixes an issue that, in some docking stations, causes the loss of internet connectivity when the Sleep mode is exited and the device is woken up.

It improves the experience of upgrading the operating system by adding technology that caches additional information about audio endpoints.

This resolves a problem that could result in the failure to play successive video clip sequences in games that use the DX12 graphics API and fixes issues that also affect games that make use of the XAudio API to play sound effects.

This resolves an issue that caused Code Integrity to continue trusting a file after it had been edited even if the file had been changed.

Furthermore, this also resolves an issue that, in certain circumstances, might cause Windows to cease functioning properly when users enable Windows Defender Application Control while also having the Intelligent Security Graph feature enabled.

Microsoft's New Features

Microsoft's newest feature in this Windows 10 KB5015878 update is that when the focus assist is activated, users have the choice to receive significant notifications. Focus assist hides notifications, similar to a do not disturb mode.

In addition, this update restores functionality for Windows Autopilot deployment situations that have lost functionality as a result of the security mitigation for hardware reuse.

Furthermore, the restriction that prevents users from using self-deploying mode (SDM) and pre-provisioning more than once has been lifted (PP).

This upgrade also allows certified manufacturers to show any User Principal Name (UPN) again in user-driven mode (UDM) installations.

Microsoft's Windows 10 Update

As announced by Microsoft, they will now integrate the most recent cumulative update with the most recent servicing stack update (SSU) for users' operating systems (LCU).

To update the Windows operating system, head over to the Settings, find and click the Update & Security button, then click Windows Update.

The link to download and install the update is located in the section titled "Optional updates available."
