Key notes

  • The first Patch Tuesday of 2024 is finally here.
  • Microsoft has launched the January 2024 security updates for Windows 11 21H2, 22H2, and 23H2 versions.
  • Besides, Windows 10 users are also getting the updates.

It’s that time of the month again – aka Patch Tuesday – for Windows 11 users. Microsoft has just launched the January 2024 security updates for the 21H2, 22H2, and 23H2 versions. 

The update for the 21H2 version, also known as KB5034121, addresses vulnerabilities, faulty ActiveX scroll bar behavior, and a critical issue where using a specific smart card for remote authentication causes unexpected system shutdowns after 60 seconds.

For those in the 22H2 and 23H2 versions, this Patch Tuesday update builds on December’s KB5033375 for 21H2, fixing similar issues and adapter problems caused by KB5032288/KB5033375 from December last year.

Last one for Windows 11 22H2 version? Well, not really: it’s only the optional, non-security enhancements for Windows 11 22H2 that will cease as of February 2024. Critical security updates will continue uninterrupted.

If you’re a Windows 10 user, this “B” release is also coming for the 20H2, 21H2, and 22H2 versions.

You can download the latest Patch Tuesday through the Settings app, then go to Windows Update or the Microsoft Update Catalog.
