    ISSUE 20.09.1 • 2023-02-28


    By Susan Bradley

    February’s patches affected you either severely, or not at all.

    The good news: If you are a consumer, home user, or business that does not use Windows Server 2022 or any version of on-premises Exchange server, you will be just fine installing the updates at this time. Therefore, I am very comfortable with lowering the MS-DEFCON level to 4.

    However, if you are a business patcher with Windows Server 2022 hosted in VMware, you may have been significantly impacted. In addition, patch administrators are still dealing with the side effects of the Exchange updates.
