  • The Windows 10 Patch Tuesday updates are rolling out now.
  • The patches contain security updates for most versions of Windows 10.
  • You can download December's updates now by checking Windows Update.

Microsoft rolled out its latest batch of Windows 10 Patch Tuesday updates today, bringing fixes to nearly all versions of the OS. This month's updates are mainly focused on security fixes, particularly with regards to Microsoft Edge Legacy, the Microsoft Graphics Component, Windows Media, Windows Fundamentals, and Windows Virtualization. As usual, there are no new features tagging along in these builds.

If you're running Windows 10 version 2004 or the 20H2 update, you'll see OS builds 19041.685 and 19042.685 (opens in new tab), respectively. Here's a look at the short list of highlights:

  • 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.

The updates for Windows 10 versions 1909 and earlier are largely the same. However, the highlights for versions 1803 and earlier contain an additional fix:

  • Addresses an issue that prevents the PDF24 app, version 9.1.1, from opening .txt files.
  • 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.

As with all Patch Tuesday updates, these are available to download for supported versions of Windows 10 now via Windows Update. Versions that are out of their support windows will receive the updates for organizations that have paid for extended security updates.
