Hi,

We used WSUS for windows update.

If a cumulative update of x for windows xx came and got approved, however, was not installed.

A month after, another cumulative update of y for windows xx came and it got approved.

If I'm going to install update y, do I need to install update x first?

If the answer is no, how far of each cumulative updates that I can jump into?

For example, there's a cumulative updates of a ,b ,c to z. I skip a to y but install z.

What is the rule?

Thanks,

choybutchoy

    Update y is a cumulative update the supersedes update x - therefore, you only need to install update y.

    https://www.ajtek.ca/wsus/how-to-setup-manage-and-maintain-wsus-part-8-wsus-server-maintenance/

    Also, a little excerpt from the documentation of WAM:

    There has been a ‘best practice’ for years where declining superseded updates should only be done after
    the superseding update is approved and the superseded update has been installed on all systems. We at
    AJ Tek are looking to change that method of thinking into a blanket declining of superseded updates. If
    you think about it, there is no need to keep the superseded updates for that long. Once testing of the
    superseding update is complete, and you are choosing to approve the superseding update, there is no
    reason for the clients to continue installing the superseded update – they should go directly to the
    superseding update which is now approved.

    @choybutchoy
    Thanks for your posting on Q&A.

    If I'm going to install update y, do I need to install update x first?
    No, there is no needed to install the old cumulative updates.

    If the answer is no, how far of each cumulative updates that I can jump into?
    Of course, it is recommended to install the latest cumulative updates. The security updates will be released monthly and the latest cumulative update will supersede the previous version. There are several hot fixes including to the cumulative update. It is not recommended to wait for several month and then install the latest cumulative update. I'm afraid that computers will encounter some troubles.

    Regards,
    Rita
