This post will guide you how to install Update Packages to a Windows 10 ISO image and use MSMG Toolkit to Add Remove Windows Components from ISO Image. Microsoft delivers cumulative updates for Windows 10 regularly. Unfortunately, it ages your pre-downloaded ISO image for Windows, and each time you deploy it, the computer must manually download the latest updates.
To circumvent this, you may update the Windows 10 ISO image by adding new updates directly to the ISO image to keep it constantly up to date. Slipstreaming is a process for doing this.
Let’s look at how you may add new updates to the image so that you don’t have to check for updates on each computer every time you install something new.
Slipstreaming refers to the process of adding new updates to pre-existing Windows setup discs. By employing the slipstream approach and adding new updates to their downloaded files, users may maintain their ISO or WIM images up to date.
This way, you won’t have to download an entire image every time a new update is made.
To add new Windows updates to an existing ISO image file, you must go through numerous steps. To add single or several updates to an ISO file simultaneously, follow the steps outlined below.
How to Add New Updates to the Windows 10 ISO Image
Depending on your level of technical knowledge, adding new updates may be difficult for some individuals. As a result, we’ve divided the process into numerous easier-to-follow steps.
If you’ve done the activity a few times, replicating the same steps might be relatively simple.
Download and extract the Windows 10 ISO files
To begin, you will require an ISO file. Using this guide, you may download Windows 10 ISO images and then extract them within a folder by right-clicking the image and selecting Extract from the Context Menu.
You may also mount the ISO image and copy the contents to a different folder.
Download updates from the Microsoft Update Catalog
You must now download the necessary update(s) directly from the Microsoft Update Catalog. Learn how to download and install any update from the Microsoft Catalog.
1. Visit the Microsoft Catalog website. We will search for “Windows 10 version 2004 x64” because the ISO image we will be deploying is Windows 10 version 2004 x64.
2. Now, click once on the last updated column header to order the updates from the most recent to the latest.
3. Now, download the most recent cumulative update and any other updates you want to include in the ISO image. We’re downloading all of the latest updates because our ISO image is outdated.
When you download these files, make sure to place them in a different folder. It would be unnecessary to download any prior cumulative or security updates because the most recent ones already incorporate all previous updates.
You must also confirm that the updates are not being prevented from executing on your computer.
Right-click on the downloaded update and choose Properties. Check the box next to Unblock, then click Apply and Ok.
If the unblock checkbox does not show, the update is never stopped.
Find the image index number
An ISO image typically comprises many editions of the same Windows, such as Professional, Education, Home, etc. Each of these editions is identified by a unique index number.
An index number is an integer connected with each of these editions necessary for future updating of the ISO image.
As a result, we must establish the index number for the edition you will deploy using this image in the future.
To find the index number, use the following command in Command Prompt:
Dism /Get-ImageInfo /ImageFile:PathForInstall.wim
PathForInstall.wim should be replaced with the path of the “install.wim” file within the extracted ISO folder, as shown below:
The output of the command would assist you in determining the index number. Because I’ll be using the Professional edition, the index number will be 6.
Mount the install.wim file
This step entails mounting the Windows 10 edition with the index 6 install.wim file before installing the update(s).
Here’s how to go about it.
1. Make a new, empty folder to mount the install.wim file.
2. In Command Prompt, type the following command to mount the install.wim file to the newly created folder:
DISM /mount-wim /wimfile:”<em>PathForInstall.wim</em>”
“Replace PathForInstall.wim with the path to the install.wim file within the extracted ISO image, IndexNumber with the index number calculated in the previous step, and PathToMountFolder with the path to the new folder created to mount the install.wim file.
Because the index number connected with Windows 10 Professional in our situation was 6, I will use the command below:
DISM /mount-wim /wimfile:”D:\Softwares\ISOs\Win10_2004_English_x64\sources\install.wim” /index:6 /mountdir:”D:\mount”
You have now mounted the install.wim file in a custom folder successfully. Please continue to the following step to add new updates to it.
Add the Windows ISO image with new updates
We’ve finally made it into the process’s limelight. This is where you may add the freshly downloaded Microsoft Catalog updates to the current ISO image.
In Command Prompt, type the following command to add an update(s) to the.wim file. Remember that the amount of PathToUpdate depends on how many updates you want to add, so adjust the command appropriately.
Dism /Add-Package /Image:”PathToMountFolder” /PackagePath=”PathToUpdate1.msu” /PackagePath=”PathToUpdate2.msu” /PackagePath=”PathToUpdate3.msu”
We’ll use the following command because we’re adding two updates to the.wim file:
Dism /Add-Package /Image:”D:\mount” /PackagePath=”D:\Updates\windows10.0-kb4577586-x64_c9bb49df325c20ddc147137b3f769fa44d800dde.msu” /PackagePath=”D:\Updates\windows10.0-kb4579311-x64_9cc8221b0ed1bc799278d029c4edadf785920da9.msu”
Depending on the size of the updates, this step may take a few minutes.
Commit and dismount
After the updates have been included in the.wim file, all that remains is to save the changes and then dismount the install.wim file. To commit the modifications and dismount, use the following command in Command Prompt.
dism.exe /Unmount-wim /mountdir:”PathToMountFolder” /commit
PathToMountFolder should be replaced with the path to the folder where the install.wim file is mount.
In this scenario, we’ll use the following command:
dism.exe /Unmount-wim /mountdir:”D:\mount” /commit
It’s worth noting that this takes a few minutes, and the Command Prompt may appear to be frozen. That, however, is not the case. Please take a few minutes for the commit and dismount to complete successfully.
Covert extracted folder back to ISO image
You may now use third-party applications to convert the updated Windows files and folders to an ISO image. This article will show you how to convert files and folders into ISO images.
Some consumers may find it easier to download a whole new version of the Windows 10 ISO image than to update an old ISO file. However, if you don’t have the time to download an entire image or need to switch to an image with the most recent updates regularly, this strategy is for you.
With a lower download volume and the most recent feature updates, updating an existing ISO image may be quick, removing the stress of updating each computer later on.
