Microsoft Releases December Patch Tuesday Updates for Windows 10

It’s Patch Tuesday and all supported versions of Windows 10 are receiving cumulative updates while version 1903 reaches end of life.

It’s that time of the month again with Patch Tuesday and Microsoft today is releasing updates for all supported versions of Windows 10. The out-of-date versions include 1709 and 1511. It’s also worth noting that today is the end of life date for version 1903. If you are running 1903 – and you can check by typing: winver into the Run line – it is probably a good idea to upgrade to version 20H2 since it’s the most recent. If you are running Windows 10 version 2004 or version 20H2 your update will come in the form of KB4592438.

KB4592438 for Windows 10 Version 2004 and 20H2

If you are running Windows 10 versions 20H2 or 2004 your update will come as KB4592438 and will bump your build to 19042.685 and 19041.685 respectively and it includes the following highlights:

  • Updates to improve security when using Microsoft Edge Legacy.
  • Updates to improve security when using Microsoft Office products.

And the update contains the following improvements and fixes:

  • Addresses a security vulnerability by preventing applications that run as a SYSTEM account from printing to “FILE:” ports. To address this issue in the future, make sure your applications or services run as a specific user or service account.
  • Security updates to Microsoft Edge Legacy, the Microsoft Graphics Component, Windows Media, Windows Fundamentals, and Windows Virtualization.

If automatic updates enabled on your system, you should see the new updates in the next couple of days. Or, you can stay on top of things by manually heading to Settings > Update & Security > Microsoft Update to check.

Older versions of Windows 10 are getting updates today as well. Make sure to read the documentation on the Windows 10 Update History page for your version’s full release notes.

If something breaks after you install today’s updates and cannot be resolved by Microsoft’s documented workarounds you can roll them back.
