Microsoft released KB5015879 for Windows Server 2022

Ready for more Windows Server action? No, we are not talking about a new RPG developed by Microsoft, we are referring to Windows Server version 2022.

We recently showed you all the details about Windows Server Build 25158 and also let you know that Windows Server 20H2 will reach end of support next month, August 2022.

Now, however, it’s time to focus on Windows Server 2022 for a few minutes and talk about KB5015879 and all the changes it brings.

What does KB5015879 bring to Windows Server 2022?

The Redmond tech giant known as Microsoft has released the July 2022 Cumulative Update for Windows Server 2022, bringing the operating system version to 20348.859, via KB5015879.

Please keep in mind that the update is a C version, which means that it is not a security update and it brings improvements to the operating system.

And, just like the latest Windows 10 Release Preview Build KB5015878, the new Server 2022 update increases input-output operations per second (IOP).

Don’t think that’s all it does, because it also fixes bugs like the one that caused Windows to freeze due to Defender.

Let’s take a look at the changelog and together learn about all the tweaks, improvements, and known issues that come with this most recent update.

Improvements and fixes

• Improves the reliability of a push-button reset after an OS upgrade.
• Addresses an issue that makes the Tenant Restrictions event logging channel inaccessible if you remove the EN-US language pack.
• Update the Remove the object Cmdlet to properly interact with Microsoft OneDrive folders.
• Addresses an issue that prevents some troubleshooting tools from opening.
• Addresses an issue that causes port mapping conflicts for containers.
• Addresses an issue that causes Code Integrity to continue to trust a file after the file has been modified.
• Addressed issue that may prevent Windows from working when you enable Windows Defender Application Control with the Intelligent Security Graph feature enabled.
• Addresses an issue that triggers lockdown policies faster when using Remote Desktop Protocol (RDP) with fast reconnect and Network Level Authentication (NLA) is disabled. This problem occurs when you call Login User() with an empty password.
• Provides the ability to configure an alternate login ID for an Azure Multi-Factor Authentication (MFA) Active Directory Federation Services (AD FS) adapter for on-premises scenarios. You can disable the alternate login ID if needed. To configure the Azure MFA ADFS adapter to ignore another login ID, run the following PowerShell command:
  • Set-AdfsAzureMfaTenant -TenantId ‘‘-ClientId’‘ -IgnoreAlternateLoginId $true.To restart the ADFS service on each server in the farm, use the adfssrv restart service PowerShell command. By default, the adapter configuration does not ignore the alternate login ID (IgnoreAlternateLoginId = $false) unless explicitly set to $ true as in the command above.
• Reduces resource contention overhead in high input/output operations per second (IOPS) scenarios that have many threads competing on a single file.
• Addresses an issue that prevents the Storage Migration Service (SMS) from completing inventory on servers that have many shares. The system logs error event 2509 in the Microsoft-Windows-StorageMigrationService/Admin channel (ErrorId=-2146233088/ErrorMessage=”Invalid table id”).
• Addresses an issue that causes Windows Profile Service to fail sporadically. The failure may occur during connection. The error message is that the gpsvc service failed to connect. Access denied.

As you can see, there were a lot of issues that needed fixing, and Microsoft did so through this recent Windows Server 2022 update.
