Foundation IT's February 2022 Patching Blog
February is upon us – already. It doesn’t feel like it was that long ago since writing the January patching blog. Compared to January, February’s feels like a friendly patch Tuesday. There has been 1 zero-day fix, and quite a few Edge updates released. The overall size of the February patch push is relatively low as well, sitting at 48 fixes plus 22 Microsoft Edge fixes too. Let’s look in more detail.

Summary
February 2022 patch Tuesday is roughly on par with the patch Tuesdays from previous years for the same month. You could say that Microsoft’s Edge is being as troublesome as we thought it would be due to the volume of updates and exploits which often come out of the woodwork. However as imagined, the updates for Windows 10 and Server 2016 are large in size. Windows 11 is more of pleasing size.
- 2022-02 Windows Server 2016 (Cumulative Update) – 1541.5 MB

- 2022-02 Windows 11 (Cumulative) – 227.5 MB
Happy Patching!
