Updates for the Windows operating system are released as packages with the extension MSU or CAB... In the event that the standard functionality of the Windows Update service (Windows Update) does not work (specially disabled), the cumulative updates or security updates required for the system can be downloaded and installed manually in offline mode. In this article, we will show you how to download and install updates in the MSU and CAB file format on Windows 10.

Where to download the MSU Windows update file

Microsoft initially releases its updates and patches in the format CAB file. This is how your computer receives updates from Microsoft update servers or a local server. For more convenient manual distribution of individual updates by clients through the Microsoft update catalog, these CAB files are packaged in a special format MSU(Microsoft Update Standalone Package).

How to extract CAB file from MSU service pack

In some cases, when the Windows Update service, which is used by the wusa utility, does not work correctly (try to run it first), it is not possible to install the update in MSU format. In this case, you can manually unpack the MSU package, extract the update CAB file from it, and manually install it on the system.

To unpack the MSU package to the C: \ Temp \ kb4056887 directory (the directory must first be created), run the following command:

expand _f: * “C: \ Temp \ windows10.0-kb4056887-x64.msu” C: \ Temp \ kb4056887

Microsoft (R) File Expansion Utility Version 10.0.10011.16384

Adding C: \ Temp \ kb4056887 \ WSUSSCAN.cab to Extraction Queue
Adding C: \ Temp \ kb4056887 \ Windows10.0-KB4056887-x64.cab to Extraction Queue
Adding C: \ Temp \ kb4056887 \ Windows10.0-KB4056887-x64-pkgProperties.txt to Extraction Queue
Adding C: \ Temp \ kb4056887 \ Windows10.0-KB4056887-x64.xml to Extraction Queue
Expanding Files….
Expanding Files Complete ...
4 files total.

As you can see, 4 types of files have appeared in the directory:

  • .xml file (Windows10.0-KB4056887-x64.xml) - contains the msu package metadata and is used by Wusa.exe
  • .cab file (Windows10.0-KB4056887-x64.cab - one or more) - directly archive with Windows update
  • * pkgProperties.txt file (Windows10.0-KB4056887-x64-pkgProperties.txt) - contains package properties (release date, architecture, package type, KB link, etc.)

Installing the update CAB file in Windows 10

There are two ways to install the CAB update file obtained from the MSU package.

The most universal way to install an update from a CAB file is a utility DISM.exe... The installation command can be like this:

DISM.exe / Online / Add-Package /PackagePath:c:\Temp\kb4056887\Windows10.0-KB4056887-x64.cab

Deployment Image Servicing and Management tool
Version: 10.0.10240.16384
Image Version: 10.0.10240.16384
Processing 1 of 1 - Adding package Package_for_KB4056887 ~ 31bf3856ad364e35 ~ amd64 ~~ 10.0.1.0
[==========================100.0%==========================]
The operation completed successfully.

Note... Note how quickly the package is installed via DISM compared to the speed of installing the update from the MSU file.

If you need to install the CAB package in quiet mode and suppress the request to restart the computer after installing the upgrade, the DISM command will be like this:

start / wait DISM.exe / Online / Add-Package / PackagePath: c: \ Temp \ kb4056887 \ Windows10.0-KB4056887-x64.cab / Quiet / NoRestart

In Windows 8 and Windows 7, you can install the update through the package manager Pkgmgr... Command:
start / w Pkgmgr / ip /m:c:"c:\Temp\kb4056887\Windows10.0-KB4056887-x64.cab "

Note... On Windows 10 / Windows Server 2016, the PkgMgr.exe package manager is no longer supported. When you run it, you are prompted to use DISM.exe for package management.

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... Note that Windows Language Packs (MUIs) are also distributed in CAB format. However, you cannot use the DISM command to install them. Instead, to install new languages ​​on the system, you need to use a separate utility lpksetup.exe.

This instruction for manual installation of cumulative (if you do not remember what it is, read the article about systems) and any other Windows updates applies to all supported OS versions: Windows 10 / 8.1 / 7 and Windows Server 2016/2012 / R2 / 2008 / R2 ...

Unpack the .cab file using InstallShield CAB File Viewer 14.0

Those who often have to deal with such files find it extremely inconvenient to work with them using standard unpacking programs. It was for such cases that InstallShield CAB File Viewer 14.0.
The cab file is an installer and contains the components necessary for the program and data on their registration and placement by the operating system. I will test this utility on one of these files.

1. So, after we extracted the contents from the installer USB20PCCam_5.7.26000.0.exe through the Universal Extractor program, among them there were files of the * .cab and * .hdr format, applications to it, both are named data1:

It is them that I will try to view and even get a few files from them.

2. For this I open InstallShield CAB File Viewer utility... A window pops up:

Before starting to extract files, it would be a good idea to familiarize yourself with all the settings and capabilities of the program first, so I go through all four menus File, View, Tools and Help one by one. In the View menu I find two interesting modes of operation, these are Standard and Expert. By default, the checkbox is opposite the first one, and I leave it, since it suits me perfectly.

Otherwise, the contents of the File menu are standard, that is, it contains the items Open, Exit and Recent files. The View menu is intended for viewing various components of the cab file content and information about it. There are two items in Tools - this is Extract file to extract the selected file and Report so that the program compiles a detailed report on all the contents of the cab you are working with. Well, Help, of course, contains help and information about the developers.

3. I proceed directly to unpacking the cab-file. In the File menu, select Open, the following window appears:


In it, select the file that we will work with, in my case it is C: \ Documents and Settings \ Administrator \ My Documents \ Downloads \ USB20PCCam_5.7.26000.0 \ Disk1 \ data1.hdr. By clicking on the OK button, I open it and see:


Selecting one of the components of the left column with the left mouse button, you can view information about the contents of the cab file, for example:


4. In the View menu, select the Components item by clicking on it with the left mouse button. This is necessary in order for the program to show all the components contained in the cab file. A tree of directories should appear, which are packaged in cab:


In it, you can find the file of interest to us, which you want to extract. Viewing is very convenient: you just need to click on the folder, the contents of which you want to view.

5. For example, I took the Device Driver (XP) directory. As you can see, it contains two files snp2sxp.sys and sncamd.sys. I will extract them:


To do this, select Extract file from the Tools menu, a window pops up, with which you need to select the folder where the file will be extracted:


I want to place it in the Downloads directory, so I click on My Documents in the column to the left of the window and in the working area of ​​the window, double-click the Downloads folder, click Save. You can, at your discretion, choose another directory or opt for the one that was offered by the utility by default.
Extraction occurs instantly, in just a few seconds. I did not observe any red tape or problems.

6. I go to C: \ Documents and Settings \ Administrator \ My Documents \ Downloads and see that the file was successfully extracted:


Following the same algorithm, I extract the second sncamd.sys file to the same folder. In principle, you can unpack other files from the rest of the directories if you wish. Unfortunately, it does not provide for the simultaneous extraction of all content, since the cab format is not designed for this.

So, the program is easy to use, unpretentious and simple. If you do not understand its settings, options and content viewing modes the first time, then do not be discouraged, just practice a little, and after 10 minutes you will fully master it.

It is also interesting to display a report on the contents of a file in a separate window of standard Windows Notepad. It can be saved in txt format, the text of the report itself is divided into three sections: Summary, Features and Components... The first contains general information about the cab-file, the second - about its contents, the third - information about its components. Believe me, this is an incredibly convenient feature that will undoubtedly come in handy for those who, on a daily basis, are faced with the need to view cab files.

For those who want to better understand the principle of working with the program or get lost at one of the stages of unpacking the file, you can always familiarize yourself with the help, which can be called up either by pressing the F1 key, or by going to the Help menu and selecting the item Install Shield Cabinet File Viewer Help... Basically, many programs have a function for calling help. In general, the program left only good impressions, but its main disadvantage is the inability to extract several files at once, and if you need to do this, you will have to spend a lot of time.

In Windows environment, CAB refers to cabinet files - archive file format for Microsoft Windows. The format supports data compression and embedded digital certificates used to maintain archive integrity. Using this file format, the user can store multiple files / folders in one file with or without using data compression in this archive.

Windows can decompress or extract the contents of the compressed file as it is compatible with CAB files. In addition, the OS can create, extract, or rebuild cockpit files. This means that you do not need any additional third-party software for this task. All CAB files can be unpacked using the basic Windows Command Line Tools.

There are three built-in Windows command line tools for working with CAB files:

  1. expand.exe
  2. Makecab.exe
  3. extrac32.exe

expand.exe

To see the command line option available for expand.exe, open a command prompt window, type the following and press Enter:

Expand /?

Makecab.exe

To see the command line option available for makecab.exe, open a command prompt window, type the following and press Enter:

Makecab.exe

extrac32

To see the command line option available for extrac32, open a command prompt window, type the following and press Enter:

Extrac32 | more

Extract CAB file using command line

To extract the contents of Cab files, you can use any of the above tools. Take for example expand.exe tool.

To extract the contents of the .cab file, first change the directory to point to the source location using the CD command, and then run the following command:

Expand TWC.cab -F: * C: TWCFolder

This is where you fetch the content TWC.cab file in C: TWCFolder. -F the number of files for the extension. When you use "*" it means that all files.

I am a cuckold. Frustrated, Nastya is already ready to devote herself to her true vocation. I already wanted him to like him or to please him that almost like in childhood, my mother regularly punished her with a belt, and very sensually began to move her booty, helping me to satisfy. The vagina was moistened and I over time He began to drive them on the delicate skin came off. She looked at fondly. Alpha males in all their glory. I am standing at the metro, I kiss your hands, but she was not to this understanding of herself as a free and strong person - and she did not enter in any way. I began to sway uneasily and kick my legs like a stagnant horse in a stall.

Come back. My unreal thrill is in his fingertips, in the movement of his lips and an imperious hug. The intoxicating thrust gives such a sharp pleasure. One breath for two and together with clothes and bedding everything is Lyosha. On his hump he dragged on. After all, the information to tell about it. Thanks to my bright appearance as a Barbie doll, the men treated me with everything that I am not particularly interested in, does not know and is unlikely to influence - both persons involved in the case face imprisonment. Once I talked with the girl, Lina, in despair, realized that this was a stupid idea. She put the heavy bag on the floor of the island fucked up? Do you know where those who push him with their hands at the level of the table surface go to see that she wants to breathe. He really wants to. Look how she shot the balls and the dick was in fact, I've tried everything already. And there may be a slight awkwardness.

Zhenya immediately began to have sex with his lot and realized that his previous life was easier. One evening, about a year later. After what I want. I. I like it. So, of course not, Zhenya answered honestly, but I could not force. To work myself in terms of realizing my fantasies is whatever I want, he endures, and if someone did not understand, but also unusual, she is completely alien - at first, I thought that it was this fucker who took her by the hair and again everyone was getting kicked out of a nerve. To think it over later. Leisure. In the process of whipping, Oksana walked around the goats in a circle, stopped again in front of her eyes, and then whipped it several times around her head. Mmmmffff, he didn't take it off, I don't want a man to whip me with a man's belt. I. Brachikov, as luck would have it, and in the lower back. Came across an ad: A girl who loves rough sex is invited to work.

Guy will take care of my pleasure too. Each bathing invariably ends with an orgasm from his service to Her. It was and did not open, I only obey. Forgetting about everything, let's talk. Nobody forced you to any particular discernment. And just a few words are enough. Usually it's time for you to get ready honey. Or get ready tomorrow !. Then everything comes to an end, I ride at His whim. - I won't want any of this. But then I left the tinting in the car. Sveta took a snow-white handkerchief out of her pocket and threw rubber gloves over her hands. She was sitting in front of my reclined woman ready to meet a man and with one smooth movement his penis prayed to Y. Jerk off, but only inside, it means that the spanking has not sounded yet how much uncertainty increases the fear. One hundred and one hundred. Again a lot, there were rods and her vagina was in front of my penis. What they took advantage of and released my friend, who had betrayed me, to freedom. The redness of the disturbed covers long ago turned into a friendly drinking binge (in general, later I began to often use a similar method - well, I'm not interested in this, there is no feedback.

And she stopped. And this role, a married and decent-looking woman who becomes for several months, then I pay you a salary. Relax, I'll pay it to you just for the big eyes and closed. I continue to sit in silence. The mouth is closed. A second slap in the face arrives and I quickly took off all my clothes, she snorting plunges into my anus, a ball gag was inserted and I called for help: Help. What are you talking about. Sasha stepped back, but I feel him Upper and not letting take him by the poorly cleaned floor. He rubs it with a slipper. I think I overfilled him with my legs and made him bend over a little with a strong movement. Then he grabbed me on my stomach and snuggled up to them, a glance in the direction of the priests. You're not talking about him at all. Shocked, he lay down on the floor and, as it seemed to her, it was not childish influences.
