Update Shows Approved/Install but NOT Installed on Client RRS feed

  • Question

  • Hi- Windows 8.1 Enterprise clients, Windows Server 2012 R2 Datacenter

    WSUS reports that a particular update (KB2889923) as Approved/Install. This update has been installed on some clients but not on others.

    It has two revisions:

    Update for Microsoft Lync 2013, 04/14/2015, revision 200, Not Approved

    Update for Microsoft Lync 2013, 04/15/2015, revision 201, Approved/Install

    I looked at the View Update History on my workstation  (one of the clients affected) and it is not listed as installed, as expected, since I don't see any sign of it (It updates Lync 2013 client to Skype for Business), but it IS listed under the Approval column on WSUS as "Install". I have other updates with the same date installed, but not this one. This is the case with a dozen or so clients (out of 50 that's a significant amount).

  • Hi,

    If you click "check for updates" manually on the client, is this update able to be found?

    We can verify the installation status in the detailed report of the update.

    Here is the screenshot of my lab:

    Besides, have you tried to install the update manually?
