Windows updates are released as packages with the MSU or CAB extensions. If Windows Update service is not working (or specifically disabled), you can manually download and install the necessary cumulative or security updates for your system. In this article we’ll show how to download and offline install updates in the MSU or CAB file formats in Windows 10.

How to Manually Download the MSU Windows Update File
Initially, Microsoft released security updates and patches in the CAB (Windows cabinet) file format. This is how your computer receives updates from Microsoft update servers or a local WSUS server. To make manual distribution of separate updates using Microsoft Update Catalog more convenient, these CAB files are packed in a special MSU format (Microsoft Update Standalone Installer Package).
You can download MSU Windows updates files (sometimes also CAB files) or files for other Microsoft products from Microsoft Update Catalog (https://www.catalog.update.microsoft.com/). Go to Microsoft Update Catalog, find and download the update you need. For example, I want to install an Adobe Flash Player security update for Windows 10 x64 1507 – KB4056887. Click Download.

Installing MSU Update File in Windows
To start the installation of a Windows update package, just double-click the MSU file you have downloaded. If the update is applicable to this computer, a Windows Update Standalone Installer window will open, where you will be prompted to confirm the update installation.
You can also install an MSU update package using wusa.exe in the command prompt.
To install the update in a silent mode (a user won’t see any pop-up windows) with a later restart, open the command prompt as administrator and run the following command:
wusa.exe c:Tempwindows10.0-kb4056887-x64.msu /quiet /norestart
Tip. Using wusa, you can also remove an update if necessary.
In some time make sure that the update has been installed successfully by running this command:
wmic qfe list | findstr 4056887
Or in the Setup event log, find an entry with the Event ID 2 from the source WUSA and the following message:
Windows update “Security Update for Windows (KB4056887)” was successfully installed. (Command line: “wusa.exe c:Tempwindows10.0-kb4056887-x64.msu /quiet /norestart”)
Please note that the installation of updates in MSU format in Windows via wusa.exe is slower than when installing the same update as CAB file. The reason is the execution of additional processing with scanning on WU / WSUS servers. See the article Slow MSU update installation.
How to Extract a CAB File from an MSU Update Package
In some cases when Windows Update that is used by wusa works incorrectly (try to reset Windows Update agent settings first), you can’t install an update in the MSU format. In this case you can unpack MSU package manually, extract a CAB file from it and install it manually in your system.
To unpack an MSU package to C:Tempkb4056887 (you have to create this folder in advance), run this command:
expand _f:* “C:Tempwindows10.0-kb4056887-x64.msu” C:Tempkb4056887

As you can see, 4 file types have appeared in the folder:
- An .xml file (Windows10.0-KB4056887-x64.xml) that contains MSU package metadata and used by wusa.exe;
- A .cab file (Windows10.0-KB4056887-x64.cab — one or more) is an archive with Windows update;
- *pkgProperties.txt file (Windows10.0-KB4056887-x64-pkgProperties.txt) that contains package properties (release date, architecture, package type, a link to the KB, etc.).
Installing a CAB Update File in Windows 10
You can install a CAB update file obtained from an MSU package in two ways.
The most common way to install an update from a CAB file is using DISM.exe. The installation command can look like this:
DISM.exe /Online /Add-Package /PackagePath:c:Tempkb4056887Windows10.0-KB4056887-x64.cab
Deployment Image Servicing and Management tool
Version: 10.0.10240.16384
Image Version: 10.0.10240.16384

[100.0%]
The operation completed successfully.
Note. Please note that the installation of a package using DISM goes faster compared to the installation of the update from an MSU file using wusa.exe.
If you have to install a CAB package in a silent mode with a later restart, use the following DISM command:
start /wait DISM.exe /Online /Add-Package /PackagePath: c:Tempkb4056887Windows10.0-KB4056887-x64.cab /Quiet /NoRestart
In Windows 8 and Windows 7, you can install an update using Pkgmgr. The command is:
start /w Pkgmgr /ip /m:c:'c:Tempkb4056887Windows10.0-KB4056887-x64.cab'

Note. The PkgMgr.exe package manager is no longer supported in Windows 10 / Windows Server 2016. When you run it, you receive a warning that you need to use DISM.exe to manage the packages.How To Install Cab Files On Windows Server 2008 R2
Note: The PkgMgr.exe has been deprecated. Please update your scripts to use dism.exe to extract, install, uninstall, configure and update features and packages for Windows.
Note. Please note that Windows language packs (MUI) are also distributed in CAB format. However, you won’t be able to use a DISM command to install them. You will have to use a separate tool, lpksetup.exe, to install new languages in your system instead.
