For example, one of the following issues may occur:
- If you try to use the /x command-line switch at a command prompt to extract the file on a Windows Vista-based computer, a dialog box that contains command-line help for the MSU opens.
- If you try to open the file on a computer that is not running Windows Vista, you cannot open the file. Instead, Windows prompts you to locate the program that created the file.
- The /x command-line switch cannot be used to extract MSU packages.
- MSU packages for Windows Vista use a file name extension that is not recognized by earlier versions of Windows.
Note The Windows Vista Expand command differs from the Expand command that is included in earlier versions of Windows.
To use the Windows Vista Expand command to expand the files from the MSU, follow these steps:
- If you are extracting a hotfix package, follow these steps:
- Double-click the Hotfix.exe file.
- In the Microsoft Self-Extractor dialog box, click Continue.
- In the Select the folder where you want to unzip the files to box, type C:\MSUFolder, and then click OK.
- At a command prompt, type the following commands. Press ENTER after each command. c:cd c:\MSUFolderexpand -F:* Saved_MSU_File_Name.msu c:\MSUFolderexpand -F:* Saved_MSU_File_Name.cab c:\MSUFolder
For example, the following programs and tools cannot extract or view the files in an IPD-aware package:
- Windows Explorer
- The Expand command that is included in earlier versions of Microsoft Windows.
- The WinZip program from WinZip International LLC.
The following Windows Vista software updates are distributed in MSU packages that contain IPD technology:
- Security updates
- Critical updates
- Update rollups
