The product group released the April 2013 Cumulative Update for the SharePoint 2013 product family.

Be aware that the SharePoint Server 2013 CU contains the SharePoint Foundation CU. And the SharePoint Server 2013 with Project Server CU contains Project Server CU, SharePoint Server CU and SharePoint Foundation CU.
That means only one package has to be installed for the SharePoint 2013 product family.

  1. Hey Stefan,

    thanks for the great information!

    I'm unsure what to do with the *.cab file in the SharePoint Server/Project Server package.

    For slipstreaming, I would extract this file and put in the updates folder.

    But what about patching an existing installation? Did I quick search but was unable to find anything. Any hint?




  2. The cab file is actually used by installing/extracing, it contains some msp files that are for some reason not in the exe file. However, you cannot slipstream this CU (or unlikely any CU until SP1) because of the dependency on the March Public Update. You need can put the PU in the Updates directory, but putting this CU there would overwrite msp files which the CU requires to be installed before in order to install. Also, extracting this update is very slow, can take from 1-2 hours..

  6. Hi Stefan,

    A maybe silly question here. I understand that SharePoint Enterprise Server includes SharePoint Server which includes SharePoint foundation. If I have SharePoint Server, do I need to apply SharePoint foundation updates, or does SharePoint server updates also
    contains Foundation updates already?



  7. And sorry, just realised that this is a 2013 post.. :p


  8. No need to apply SharePoint foundation patches.
