Windows Updates may now Expire
October 21, 2021
https://www.ghacks.net/2021/10/21/windows-updates-may-now-expire/

Microsoft enabled a new update expiration policy recently for Windows updates. Updates released for Windows may be flagged as expired by the company now, and that means that these updates won't be available anymore through Windows Updates, the Microsoft Update Catalog or other release channels.

Additionally, an "EXPIRATION NOTICE" is added to the page at the very top that explains what this means.

IMPORTANT As of 8/5/2021, this KB is no longer available from Windows Update, the Microsoft Update Catalog, or other release channels. We recommend that you update your devices to the latest security quality update.
On Windows Server Update Services, a new banner is displayed at the top that highlights if an update has expired.

Only cumulative updates will expire according to Microsoft. Security-only updates for the client and server operating systems Windows 7 SP1, Windows 8.1, Windows Server 2008 R2, Windows Server 2008 SP2, Windows Server 2012, and Windows Server 2012 SP2 won't expire because "they are not cumulative and hold only one month worth of fixes".

Microsoft notes that older packages are also not expired if a newer update package has a dependency that has not "been superseded by a newer package".

Microsoft: Windows update expiration policy explained

Microsoft produces two to three updates per supported Windows platform monthly. This results in a backlog of updates and potentially increases the size of update packages. Many of these updates, however, are cumulative and include all earlier updates that have been published for that platform. That means, when older packages expire, you still receive the updates contained in those packages by installing the cumulative update.

By expiring older, redundant packages, you get better performance, shorter scan times, a faster user experience, and reduced risk of deploying older updates which have been superseded with newer, more secure ones. Here are answers to common questions we receive about our Windows update expiration policy.
