A CAB is a compressed archive, so its contents determine how to use it. A Windows servicing package can be installed with DISM or Add-WindowsPackage. A driver CAB needs a driver-installation workflow instead. First check the publisher’s instructions and confirm which type you have.
Step-by-Step Tutorial for Installing CAB Files on Windows 10
The steps below are for a Windows servicing CAB from a trusted publisher. Confirm its required Windows version, architecture, and prerequisites before continuing. Back up important data and keep the PC connected to power.
Step 1: Locate the CAB File
Identify where your CAB file is located on your computer.
Ensure you remember the path to this file, as you will need it to execute commands in the following steps. It’s often helpful to move the CAB file to an easy-to-access location, like your desktop, to make the process smoother.
Step 2: Open Command Prompt or PowerShell as Administrator
Run Command Prompt or PowerShell with administrative privileges.
To do this, type “cmd” or “PowerShell” in the search bar, right-click on the application, and select “Run as administrator.” This step is crucial, as installing system files requires administrative permissions.
Step 3: Use the Command Line to Install the CAB File
Type the appropriate command to install the CAB file.
In an administrator Command Prompt, use DISM /Online /Add-Package /PackagePath:"C:\Packages\update.cab". Replace the entire example path with your actual CAB path, keeping the quotes. /Online means the Windows installation currently running.
Alternatively, in administrator Windows PowerShell, run Add-WindowsPackage -Online -PackagePath "C:\Packages\update.cab". Choose one method; you do not need to install the same package twice.
Step 4: Wait for the Installation to Complete
Allow the process to finish without interruption.
The Command Prompt or PowerShell will display progress updates. Depending on the size of the CAB file, this might take a few minutes. Patience is key, as interrupting the process could lead to incomplete installations.
Step 5: Restart Your Computer
Reboot your system to apply the changes.
Restart if the tool or package instructions require it. Save your work before restarting.
Confirm the tool reported success. You can review installed packages with DISM /Online /Get-Packages /Format:Table. An error or pending restart is not the same as a completed installation.
Tips for Installing CAB Files on Windows 10
- Always back up important data before installing new drivers.
- Verify the source of the CAB file to ensure its legitimacy and safety.
- Use a reliable antivirus program to scan the CAB file for malware.
- If you’re unsure about a command, look it up to avoid errors.
- Keep your system updated to ensure compatibility with new files.
Frequently Asked Questions
What is a CAB file in Windows 10?
A CAB file is a compressed archive that contains installation files for Windows applications or drivers.
Can I open a CAB file without installing it?
Yes, you can extract the contents using file compression software like WinRAR or 7-Zip.
Why isn’t my CAB file installing?
Record the exact error. Check the full path, administrator rights, package type, Windows version, architecture, and required earlier updates. Do not bypass compatibility checks simply to force installation.
Do CAB files work on all versions of Windows?
The archive format can be used across Windows versions, but a package inside it may target only a particular version, build, architecture, or device.
Is there a risk in installing CAB files?
System updates and drivers can affect how Windows works even when they come from a trusted publisher. Follow that publisher’s instructions, check compatibility, and keep a recovery option available.

Driver CABs and Other Archives
Do not send every CAB to DISM /Add-Package. For a driver archive, follow the hardware vendor’s extraction and installation instructions. PnPUtil works with the extracted INF driver package; it is separate from Windows servicing. An ordinary archive may only need extraction, not installation.
