What’s New in Update KB5000841 for Windows 7 Mar 10, 2021 16:17 GMT Windows 7 no longer receives security updates since January Microsoft has shipped a new Windows 7 monthly rollup as part of the March 2021 Patch Tuesday cycle, but once again, this one is shipped only to devices configured to receive Extended Security Updates. Windows 7 has already been retired in January 2020, so only computers that are enrolled in Microsoft’s ESU program, and thus getting custom security updates in exchange for a fee, are getting this monthly rollup. Organizations that have already registered their devices for custom updates are therefore provided with monthly rollup KB5000841, which includes several security improvements, including for Windows Fundamentals, Windows Shell, Windows UAC, and Windows Media.
