    ISSUE 20.23.1 • 2023-06-08

    By Susan Bradley

    We’re nearly halfway through the 2023 patching year, almost to the end of the road for Windows 10 21H2.

    But before we delve into that: Patch Tuesday is just around the corner, so it’s time to get conservative and defer patches. Accordingly, I’m raising the MS-DEFCON level to 2.

    Microsoft is indicating that it will “force” 21H2 machines to 22H2, but I have news for them — if you don’t have 22H2 and you are not using one of the methods to hold off on feature releases (Group Policy, registry key, etc.), chances are you have some sort of issue that is blocking the install. Some of the blocks may be driver-related, and some may be the result of underlying corruption in the code that handles patching.

    Anyone can read the full MS-DEFCON Alert (20.23.1, 2023-06-08).
