And, if you were wondering if these obsolete versions of the OS still receive security fixes and updates, the answer is yes, they still do. While we’re talking about Patch Tuesday and updates, don’t forget to check out the Adobe batch of monthly software, the list of addressed Windows 10 CVEs, the Windows 11 section, and also the article with direct download links.

Whar’s new on Windows 8.1?

During this month’s security fix rollout, Microsoft has also announced the launch of KB5010419, which is the cumulative update for Windows 8.1 and Windows Server 2012 R2. However, unlike the Windows 11 Patch Tuesday update, which has a slender set of release notes, the Windows 8.1 update has quite a long list of notes and issues. In many users’ opinions, the highlight of this release is the patch that addresses an issue in which Virtual Machines (VMs) on a Windows server that has Unified Extensible Firmware Interface (UEFI) enabled fail to start after installing the January 11, 2022 Windows update. The rest of the improvements and fixes added this month are as follows:

Updates daylight savings time to start in February 2022 instead of March 2022 in Jordan.

Addresses an issue in which Windows stops running with an IRQL_NOT_LESS_OR_EQUAL error.

Addresses an issue in which a Lightweight Directory Access Protocol (LDAP) modify operation that contains the SamAccountName together with the UserAccountControl attributes fails with “Error: 0x20EF The directory service encountered an unknown failure.”

Adds an audit event on Active Directory domain controllers that identifies clients that are not RFC-4456 compliant. For more information, see KB5005408—Smart card authentication might cause print and scan failures.

Known issues

If you are still running Windows 8.1 and you want to install this update, just open up Windows Update and apply any available updates. You will also automatically be offered the latest servicing stack update (KB5001403) which should improve the reliability of the update install process.
