KB5049981

This January 2025 Patch Tuesday is bringing the usual roll-up of updates to Windows 10. The updates are available for Windows 10 20H2, Windows 10 21H2, and Windows 10 22H2 (versions 2004, 20H2, and 21H2, respectively) with KB5049981.

KB5049981 has a few known issues (also present in the updates for Windows 11). One issue prevents the OpenSSH service from starting in some instances after the October 2024 update and requires some manual intervention to fix. Microsoft is aware of the issue and is working on a fix.

Another issue may prevent specific devices with Citrix components installed from installing the updates. Devices with the Citrix Session Recording Agent (SRA) version 2411 might be unable to complete the update install process and will roll back to the previous build. Microsoft is working with Citrix to address the issue.

In addition to updates to the latest supported versions of Windows 10, Microsoft is also releasing updates for some older versions of the OS. The updates are as follows:

  • Windows 10 1809: KB5050008
  • Windows 10 (LTSC) 1607: KB5049993
  • Windows 10 (LTSC) 1507: KB5050013

If you prefer to install the Patch Tuesday Updates for Windows 10, manually, you can do so by downloading the KB5049981 patch from the Microsoft Update Catalog, here. The update should be in Windows Update if you’re a home user.

You should install KB5049981 as soon as possible—the Patch Tuesday updates for January 2025 address 8 zero-day vulnerabilities from 159 CVEs.
