- A User Account Control (UAC) prompt may appear; click “Yes” to grant permission.
-
Navigate to the CAB File Directory (Optional but Recommended):
While you can provide the full path in the command, navigating to the directory first can simplify the command and reduce potential errors.- If your CAB file is at
C:UpdatesMyUpdate.cab, you would type:
cd C:Updates
And press Enter.
- If your CAB file is at
-
Execute the DISM Command:
Once in the correct directory (or if providing the full path), type the following command and press Enter:
DISM /Online /Add-Package /PackagePath:"C:pathtoyourfile.cab"Explanation of the command:
DISM: Invokes the Deployment Image Servicing and Management tool./Online: Specifies that the operation should be performed on the currently running operating system (as opposed to an offline image)./Add-Package: Instructs DISM to add a package (which a CAB file essentially is) to the Windows image./PackagePath:"C:pathtoyourfile.cab": Specifies the full path to your CAB file. Crucially, enclose the path in double-quotes if it contains spaces.
Example:
If your CAB file is located atC:Windows UpdatesKB123456.cab, the command would be:
DISM /Online /Add-Package /PackagePath:"C:Windows UpdatesKB123456.cab" -
Monitor the Installation Process:
DISM will display progress messages. The installation can take several minutes, depending on the size and complexity of the CAB file.- You’ll typically see messages like “Deployment Image Servicing and Management tool,” “Version: [version number],” and then progress indicators.
- Upon successful completion, you should see a message stating “The operation completed successfully.”
-

It also integrates DISM functionalities through specific cmdlets (PowerShell commands).

Step-by-Step Guide:
-
Open PowerShell as Administrator:
- Click the Start button.
- Type
powershellin the search bar. - Right-click on “Windows PowerShell” (or “PowerShell” if on Windows 10/11) in the search results.
- Select “Run as administrator.”
- A UAC prompt may appear; click “Yes.”
-
Execute the PowerShell Command:
Type the following command and press Enter:
Add-WindowsPackage -Online -PackagePath "C:pathtoyourfile.cab"Explanation of the command:
Add-WindowsPackage: This is a PowerShell cmdlet that adds packages (including CAB files) to a Windows image. It essentially wraps the DISM functionality in a more PowerShell-native syntax.-Online: Similar to the DISM command, this parameter specifies that the operation should be performed on the currently running operating system.-PackagePath "C:pathtoyourfile.cab": Specifies the full path to your CAB file. Again, use double-quotes if the path contains spaces.
Example:
If your CAB file is located atD:DriversNewGPU.cab, the command would be:
Add-WindowsPackage -Online -PackagePath "D:DriversNewGPU.cab" -
Monitor the Installation Process:
PowerShell will display the installation progress. It typically provides less verbose output than DISM until completion.- Upon success, you’ll receive a message confirming the operation completed.
