Around 2011, Microsoft began patching Sharepoint Server by component rather than the software as a whole. While I’m sure this makes perfect sense for Microsoft, it has made things a bit more confusing in terms of figuring out which patches are required for which system.

To determine if you do or don’t have the components a patch is installing you can follow these steps:


    KB2553094 from MS11-072 (Excel Services on Sharepoint Server 2010)

1. Download the patch


2. Extract the patch (Using a tool that supports unzipping self extracting exe files eg. 7zip)

3. Open the .xml file (on 2007 it’s a .cif file)


4. Locate the product GUID. There may be more than one.


5. On your Sharepoint host run:


6. Navigate to the Uninstall folder


7. Check if the folder contains the GUID(s) found in step 4


Using this method you can better understand which patches apply to your system, and which do not.

Note that I’ve emphasized the second set of digits in the GUID, in my example ‘1138’. For quick reference you only need to compare this value.

For reference, below is a list of patched components, the 2nd set of digits from the GUID, and the component’s display name:
