1. Open Command Prompt as Administrator.
2. Execute the following command, replacing `` with the actual file path:

“`
dism /online /add-package /packagepath: “`

1. Wait for DISM to process and install the package.
2. Restart the computer if prompted.

Using Windows PowerShell to Install Updates

Windows PowerShell offers a powerful alternative for installing updates, particularly useful for scripting and automation. Using the `Add-WindowsPackage` cmdlet or invoking DISM commands within PowerShell allows for seamless integration into administrative workflows.

Example PowerShell command to install a CAB update:

“`powershell
dism /online /add-package /packagepath:”C:\Updates\windows10.0-kb1234567.cab”
“`

PowerShell scripts can be expanded to:

• Verify update prerequisites.
• Log installation progress.
• Handle errors and retries.

Administrators should ensure that PowerShell is running with elevated privileges to avoid permission issues during installation.

Tracking and Verifying Installed Updates

After manual installation, it is critical to verify that updates have been applied successfully. Windows provides several methods to track installed updates:
