Microsoft’s November 2021 Patch Tuesday is now live and sending cumulative updates out into the wild. This is the second Patch Tuesday since Microsoft launched Windows 11 last month, and it addresses several security holes in the new platform.

Specifically, Windows 11 is receiving the KB5007215 update, which brings the OS to build 22000.318. Microsoft says the security patch is a “B” release and is available for all versions of Windows 11 and Windows 10 that the company supports.

In build 22000.318, Microsoft points to the following changes:

“Addresses an issue in which certain apps might have unexpected results when rendering some user interface elements or when drawing within the app. You might encounter this issue with apps that use GDI+ and set a zero (0) width pen object on displays with high dots per inch (DPI) or resolution, or if the app is using scaling.”

As usual, only the newest fixes in this update will install onto a device. In other words, this release will not override previous updates but will add to the team. You can see details on security fixes for Windows 10 here and for Windows 11 here.

Build 22000.280

Microsoft is also rolling out build 22000.280 for Windows 11 servicing stack update (SSU). Here the focus is on general quality improvements.

“This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates.”

As usual, Microsoft also lists some known issues with the update.
