Recently in the news about fresh cumulative updates we began to provide links where you can download .cab or .msu files of assembly data. In this article we will figure out why they are needed and how to use them.

What are CAB and MSU files

In Windows 10, there are several file formats used to update certain system components. This:

ESD files. They are an encrypted and highly compressed ISO image. They are used to install major updates (assemblies in which not only the index, but also the main number changes). With their help you can, for example, .
CAB or MSU files. They are, one might say, archives. Used to install small updates - cumulative, security updates, Adobe updates Flash Player and so on.

All mechanisms for working with these files are built into the system. These are what the Update Center uses - it just downloads required file, and then automatically does what is described in this instruction. The disadvantages of this approach are the inability to install any updates offline, which some users need from time to time.

Let me immediately note that in Windows 10, a CAB or MSU file of some cumulative update also contains all previous cumulative updates! There is no need to first, for example, install assembly 14393.187, then .189, then .222. It is enough to immediately install the latest package.

Where to download Windows 10 update MSU file

How to install CAB and MSU

Download the CAB or MSU file.
Move it to a folder with some shortcut. That is, it is better that the path to the file is, for example, C:\CAB\update.cab, but not C:\Users\Public\Downloads\Folder\CAB Files\CabFile1\update.cab.

Installing CAB files

Installing MSU files

Everything is a little easier with them. They can be installed even by simply double-clicking on them. But there is a way to do this through the console.

Update file used by Windows Update, an application included with Windows composition Vista, Windows 7 and Windows Server. Contains updates for applications and files. Installed using Windows programs Update Stand-alone Installer (Wusa.exe), which is automatically downloaded by Windows Update (generally, the user does not need to manually install MSU files).

Each MSU file contains 4 elements:

Windows Update metadata describing the update package

One or more .CAB files that store update data

.XML file describing the contents of the MSU file

Properties file read by Wusa.exe application

You can manually extract the contents of MSU files by typing Windows line following:
expand -f:* "example.msu" output_directory

You can then manually install the update package by typing the following command:
pkgmgr.exe /n:output_directory\example.xml
(example.msu and example.xml have the same prefix names).

NOTE: Earlier versions operating systems Windows uses .MSI extension files for updates.
