When you try to extract and to view the contents of a Microsoft Update Standalone Package (MSU) for Windows Vista, you cannot extract the files from the MSU. Here we are going to explain how to extract those hotfix details without using any third party tools
Operating Systems
Windows 2008 server,
Windows 7
Windows Vista,
Windows 10,
Windows server 2012
You cannot extract the contents of a Microsoft Update Standalone Package for Windows vista onwards.
These issues may occur for the following reasons:
 The /x command-line switch cannot be used to extract MSU packages.

To resolve this issue, use the Windows  Expand command to extract and to view the files in an MSU. The Expand command is included in later editions of Windows  and in the Windows Vista OEM Pre-installation Kit (OPK). 

Coming to the scnario
We have a Microsoft patch. But we have no idea about that whether this fix for windows vista or windows 7 or windows 2008 server.
For Windows XP Professional or Windows Server 2003, whether a fix can be applied into it is judged from the name of the fix. But it’s not so obvious for Windows Vista or Windows Server 2008. The information to judge it is including in a .txt file expending from the .msu files of this fix.  Here we are explaining how to get those details using  expand command.
 For testing purpose , hotfix Windows6.0-KB928439-x86 is downloaded.  Suppose that Windows6.0-KB928439-x86.msu file is put under folder G:\Patchlist.
Firstly type the following command at a command prompt to expand the .msu file to a particular folder:
     expand -f:* "G:\ patchlist\Windows6.0-KB928439-x86 " G:\patchlist
The folder now contains one or more subfolders and files that have .mum and .manifest file name extensions. The subfolders contain the files that are updated by the MSU. The files describe the file operations, the registry modifications, and the other operations that need to be completed to install the component

Here we are created one folder patchlist for getting the output result.
Then you can get following contents from file G:\patchlist
  • Windows Update metadata
                             This metadata describes each update package that the .msu file contains.
  • One or more .cab files
               Each .cab file represents one update.
  • An .xml file
               This .xmL file describes the .msu update package.
  • A properties file
    This file contains string properties we use to identify whether this fix can be applied to Vista or Server 2008.
Open the properties file under the G:\patchresult folder .Open the txt file named Windows6.0-KB928439-x86-pkgProperties.txt. There is a string property named Applicability Info. This property tells that which windows 6.0 systems the hot fix can be applied to.

Note: The Expand command used here are differs from the Expand command that is included in earlier versions of Windows.

To use the  Expand command to expand the files from the MSU, follow these steps:
  1. If you are extracting a hotfix package, follow these steps:
    1. Double-click the Hotfix.exe file.
    2. In the Microsoft Self-Extractor dialog box, click Continue.
    3. In the Select the folder where you want to unzip the files to box, type C:\MSUFolder, and then click OK.

ApplicabilityInfo="Windows Vista SP1; Windows Server 2008;" /*This property tells to which systems hotfix 928439 can be applied to.*/
