What you need to know

  • November 2021's Patch Tuesday is here for Windows operating systems.
  • KB5007186 has arrived for Windows 10 21H1, 20H2, and 2004, while there is KB5007215 for Windows 11.
  • This month is security focused, with all supported OSes receiving patches for various issues and vulnerabilities.

If you're rocking Windows 11 or Windows 10, here's the scoop: November 2021's Patch Tuesday isn't packing any particularly fun highlights or fancy feature updates. Instead, you're getting security.

A sextet of zero-day vulnerabilities have been handled, including two that were being actively exploited (CVE-2021-42292 and CVE-2021-42321).

You can check out the Windows 10 updates over on Microsoft's patch note blog, wherein you'll see nothing major beyond security updates and a servicing stack notification, as are standard for every Patch Tuesday. However, Microsoft does include a heads-up in its November log:

Because of minimal operations during the holidays and the upcoming Western new year, there won't be a preview release (known as a "C" release) for the month of December 2021. There will be a monthly security release (known as a "B" release) for December 2021. Normal monthly servicing for both B and C releases will resume in January 2022.

On the Windows 11 side, there's KB5007215, which is, again, focused on security. However, you can check out Microsoft's support bulletin for more details, one of which includes that a GDI+ issue has been remedied. And as always, servicing stack updates are present, because that's what happens on Patch Tuesday.

In summary, a low-key month for updates. There's a chance that based on Microsoft's notice regarding December (posted above), the final month of 2021 may also be light on content. That is, unless something massive crops up that pushes Microsoft into overdrive. Like, say, a print nightmare.
