General Question for approving multiple updates on Servers

    I often have to approve groups of updates. I have seen in some cases the
    WSUS Clients download all or some of the approved updates. Then after
    installation is completed it will pick up more or the rest of the updates.
    What is the criteria for grouping the updates? Also is this the approved
    method of updating a server or should we be approving one update at a time?

    One other question, in some cases we cannot reboot our servers immediately
    after installing the updates with WSUS. Is there any danger to the server in
    not rebooting immedaitely after the update is installed or can the server
    function properly until a reboot can be scheduled with the business areas?

  2. No, multiple updates at once is fine. In most cases all available updates
    should install simultaneously.
    The server will not be stable until it is rebooted. You should wait until you
    can reboot before installing the updates.

    Is there any ryhme or reason to which updates are downloaded in groups and
    others one by one.

  4. Some updates won't install until other updates have been applied. This is
    especially true if one of the group of updates is a Service Pack.

  5. In almost all cases if you're applying only a single month's worth of updates
    they'll all install at once. In fact I don't think I've ever seen a month's
    worth of updates fail to install simultaneously.

    Updates install separately when one update is a prerequisite for another
    (relatively rare) or when one update installs a new component which then needs
    to be patched.

    On rare occasions I've seen a server fail to download newly approved updates
    until the updates that were already downloaded were installed. I believe this
    was a bug in the old version of the WSUS client software, but it might still be
    present; if you're seeing this on a regular basis it may be worth
    troubleshooting to try to resolve the problem.
