Installation instructions

To resolve this issue for OEM partners, integrate the hotfix package into the installation image of Windows 7. To do this, follow these steps:

1. Download all the necessary files and tools. To do this, follow these steps:

   1. Install the Windows 7 OEM Preinstallation Kit (OPK).
      

   2. Copy the hotfix package to a folder on the computer. For example, copy the package to the folder C:\Test\Updates.

   3. Copy the Install.wim file from the Windows 7 installation media to the computer. For example, copy the Install.wim file to the folder C:\Test\Images.

2. Add the hotfix to a Windows 7 image. To do this, follow these steps:

   1. Click Start, click All Programs, click Windows OPK, right-click Deployment Tools Command Prompt, and then click Run as administrator.

   2. At the command prompt, retrieve the name or the index number for the image that you want to change. To do this, type the following command, and then press Enter:

      Dism /Get-WIMInfo /WimFile:C:\test\images\install.wim

   3. Notice the index number or the name of the Windows 7 image to which you will add the hotfix.

   4. Use a DISM command to mount the image by using the index number or the name that you noticed in step 2C. For example, the index number of the image to which you will add the hotfix is 3. The following command mounts Index 3 to a folder that is named "offline" in the test directory:

      Dism /Mount-Wim /WimFile:C:\test\images\install.wim /Index:3 /MountDir:C:\test\offline  

      Note You must create the C:\Test\Offline folder before you mount the image.

   5. At the command prompt, type the appropriate command to add the hotfix, and then press Enter.
      
      For x86-based versions of Windows 7:

      Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\test\updates\Windows6.1-KB2519949 -x86.msu For x64-based versions of Windows 7:

      Dism /Image:C:\test\offline /Add-Package /PackagePath:C:\test\updates\Windows6.1-KB2519949 -x64.msu

   6. At the command prompt, type the following command to commit the changes and to unmount the image, and then press Enter:

      Dism /Unmount-WIM /MountDir:C:\test\offline /Commit
