Installing Windows 8.1 Update
You can update
your existing Windows 8.1 images by applying the update. You can create multilingual images by installing the Windows 8.1 Update MSU file to a Windows 8.1 image, however be sure to install the files in the correct order:
1. Start with your installation of Windows 8.1 RTM. This can be a base language image or an image with multiple languages.
2. Install one or more Windows 8.1 RTM languages to the image, if necessary.
3. Important: Install all of the previously-released updates for Windows 8.1.
This includes:
· Rollup A (KB2883200)
· Rollup B (KB2884846)
· November Rollup (KB2887595)
· December Rollup (KB2903939)
· January Rollup (KB2911106)
· Any other previously-released Windows Updates.
4. Boot the Windows 8.1 image to audit mode (CTRL+Shift+F3 at the OOBE screen).
5. Important: Install Windows8.1-KB2919442-<architecture>.msu update, where <architecture> is x86, x64, or arm by double-clicking on the file. This is required to install
before you install the Windows 8.1 Update MSU update.
6. Restart your PC. You must restart the PC to complete any pending update actions.
7. Install the Windows 8.1 Update MSU file, Windows8.1-KB2919355-<architecture>.msu (where <architecture> is x86, x64, or arm) to the image by double-clicking on the file.
The update will
be applied for all available languages installed in the image.
8. Restart your PC. You must restart the PC to complete any pending update actions.
9. Boot the PC
and make any additional customizations.
Prepare your installation to be captured by running Sysprep /generalize /oobe.
Note If you add additional language packs after installing Windows 8.1 Update online, then a user will
be prompted to download the language resources for Windows 8.1 Update from Windows Update. If you install additional
language packs after applying the MSU update to an offline image, you can re-apply the MSU update to install the localized update files. This behavior might change
in a future release.
To install the MSU to an offline Windows
8.1 image:
1. Start with a Windows 8.1 image that includes all of the previously released updates, including:
· Rollup A (KB2883200)
· Rollup B (KB2884846)
· November
Rollup (KB2887595)
· December Rollup (KB2903939)
· January Rollup (KB2911106)
2. Create a mount directory for your install.wim and winre.wim files and mount the images:
md C:\mount\Windows
md C:\mount\WinRE
Dism
/Mount-Image
/ImageFile:"<path>\install.wim"
/index:1
/MountDir:C:\mount\Windows
Dism
/Mount-Image
/ImageFile:"C:\mount\Windows\Windows\System32\Recovery\winre.wim"
/index:1
/MountDir:C:\mount\WinRE
3. Apply the Windows 8.1 Update MSU files to both of the install.wim and winre.wim images.
Dism /Add-Package /PackagePath:C:\packages\Windows8.1-KB2919442- x64.msu /Image:C:\mount\Windows
/LogPath:AddPackage.log
Dism /Add-Package /PackagePath:C:\packages\Windows8.1-KB2919442- x64.msu /Image:C:\mount\WinRE
/LogPath:AddPackage.log
Dism /Add-Package /PackagePath:C:\packages\Windows8.1-KB2919355- x64.msu /Image:C:\mount\Windows
/LogPath:AddPackage.log
Dism /Add-Package /PackagePath:C:\packages\Windows8.1-KB2919355- x64.msu /Image:C:\mount\WinRE
/LogPath:AddPackage.log
4. Unmount the recovery image and commit the changes. For example:
Dism
/Unmount-Image /MountDir:C:\mount\Winre /Commit
5.
Export a copy of the winre.wim image and then delete winre.wim file from the install.wim file. For example:
Mkdir C:\RecoveryWIM
Dism
/Export-Image
/SourceImageFile:"C:\mount\Windows\Windows\System32\Recovery\winre.wim"
/SourceIndex:1 /DestinationImageFile:"C:\RecoveryWIM\winre2.wim"
Del "C:\mount\Windows\Windows\System32\Recovery\winre.wim"
6. Unmount the Windows image and commit the changes. For example:
Dism
/Unmount-Image /MountDir:C:\mount\Windows
/Commit
7.
Apply the install.wim image to your Reference PC and then boot it. All
pending installation actions will complete and you will
be able to generalize and recapture the image.
Important: You must apply and boot the image after adding the MSU files to complete the installation.
To automate
installation of the
MSU files on a running Windows
8.1 image:
To automate the installation of these .msu files, you can use the DISM command in a script. However, if you are automatically installing the MSU to a running Windows installation, you must first extract the contents of the .msu file.
1. Start with a Windows 8.1 image that includes all of the previously released updates, including:
·
Rollup A (KB2883200)
· Rollup B (KB2884846)
· November Rollup (KB2887595)
· December Rollup (KB2903939)
· January Rollup (KB2911106)
1. Copy the Windows 8.1 Update MSU files to a local directory. In this example, C:\MSU is used for the
MSU files and C:\CAB is used for the extracted files. Expand the CAB file from the MSU.
For example:
Mkdir C:\CAB
Expand C:\MSU\Windows8.1-KB2919442-x64.msu C:\CAB –F:*
Expand C:\MSU\Windows8.1-KB2919355-x64.msu C:\CAB –F:*
2. Use DISM to apply the cab file. For
example:
DISM /online
/add-package /packagepath:C:\CAB\Windows8.1-KB2919442- x64.cab
DISM /online
/add-package /packagepath:C:\CAB\Windows8.1-KB2919355- x64.cab
Note that you will also need to update the winre.wim file in the running image with the same MSU files. See the instructions above for installing the MSU files to an offline image.
