What is Slipstreaming?

Slipstreaming is a process of adding Windows update packages into the Windows setup file. In short, it is the process of downloading Windows updates and then building a separate Windows installation disk which includes these updates. This makes the update and installation process more efficient and faster. However, using the slipstreaming process can be quite overwhelming. It may not be as beneficial if you do not know the steps to be performed. It may also cause more time than the normal way of updating Windows. Performing slipstreaming without prior understanding of the steps may also open risks for your system.

Slipstreaming proves very beneficial in a situation where you need to install Windows and its updates on multiple computers. It saves the headache of downloading updates over and over and also saves ample amount of data. Also, the slipstreaming versions of Windows allow you to install a fresh up to date Windows on any device.

But you do not need to worry a bit because, in this article, we are going to tell you everything that you need to know in order to perform Slipstream on your Windows 10. Let us get on with the first requirement:

#1. Check all the Installed Windows Updates & Fixes

Before working on updates and fixes, it is better to know what all is going on with your system at the moment. You must have a knowledge of all patches and updates installed in your system already. This will also help you check the updates along the whole slipstreaming process.

Search for Installed Updates in your Taskbar search. Click on the top result. The installed updates window will open from the Programs and Features section of the system settings. You can minimize it for the time being and move to the next step.

#2. Download Available Fixes, Patches & Updates

Generally, Windows downloads and installs updates automatically, but for the slipstream process of Windows 10, it needs to install files of individual update. However, it is very complex to search for such files in the Windows system. Therefore, here you can use the WHDownloader.

1. First of all, download and install the WHDownloader. When installed, launch it.

2. When launched, click on the arrow button on the top left corner. This will fetch you a list of updates that are available for your device.

Click on the arrow button in WHDownloader window

3. Now choose the version and build a number of your Operating System.

4. Once the list is on the screen, select all of them and click ‘Download’.

You can also use a tool called WSUS offline update instead of WHDownloader. Once you get the updates downloaded with their installation files, you are ready to move to the next step.

#3. Download Windows 10 ISO

In order to Slipstream your Windows updates, the primary requirement is to download the Windows ISO file on your system. You can download it through the official Microsoft Media Creation tool. It is a standalone tool by Microsoft. You do not need to perform any installation for this tool, you only need to run the .exe file, and you are good to go.

However, we strictly prohibit you from downloading the iso file from any third-party source. Now when you have opened the media creation tool:

1. You will be asked if you want to ‘Upgrade the PC now’ or ‘Create installation media (USB Flash drive, DVD or ISO file) for another PC’.

2. Choose ‘Create installation media’ option and click Next.

3. Now select your preferred language for further steps.

5. Now that you have chosen the language, edition, and architecture, click Next.

6. Since you have chosen the installation media option, you will now be asked to choose between ‘USB flash drive’ and ‘ISO file’.

On Choose which media to use screen select ISO file and click Next

7. Select the ISO file and click Next.

Windows will now start downloading the ISO file for your system. Once the download has been finished, navigate through the file path and open Explorer. Now go to the convenient directory and click Finish.

#4. Load Windows 10 ISO data files in NTLite

Now that you have downloaded and installed the ISO, you need to modify the data in ISO file according to the compatibility of your Windows computer. For this, you will need a tool called NTLite. It is a tool from Nitesoft company and is available at for free.

The installation process of NTLite is same as that of ISO, double click on the exe file and follow on-screen instructions to complete the installation. First of all, you will be asked to accept the privacy terms and then specify the install location on your computer. You can also opt for a desktop shortcut.

1. Now that you have installed the NTLite tick the Launch NTLite checkbox and click Finish.

2. As soon as you launch the tool, it will ask you about your version preference, i.e., free, or paid version. The free version is fine for personal use, but if you are using NTLite for commercial use, we recommend you buy the paid version.

Launch NTLite and select Free or Paid Version | Slipstream Windows 10 Installation

3. The next step will be the extraction of files from the ISO file. Here you need to go to the Windows File Explorer and open the Windows ISO file. Right-click on the ISO file and select Mount. The file will be mounted, and now your computer treats it as a physical DVD.

right-click that ISO file which you want to mount. then click the “Mount” option.

4. Now copy all the required files to any new directory location on your hard disk. This will now work as a backup if you make a mistake in further steps. You can use that copy if you want to start the processes again.

double click the ISO file you want to mount.

5. Now come back to NTLite and click on the ‘Add’ button. From the dropdown, click on Image Directory. From the new dropdown, select the folder where you copied the content from ISO.

8. Now you need to choose one of the editions to modify. We recommend you go with the Home or Home N. The only difference between Home and Home N is the media playback; you do not need to worry about it. However, if you are confused, you can go with the Home option.

Now you need to choose one of the editions to modify then click on Load

Now you can use the USB drive to install that slipstream Windows version. The trick here is to plug the USB before booting the computer or laptop. Plug the USB in and then press the power button. The device may begin downloading the slipstreamed version on its own, or it may ask you if you want to boot using the USB or normal BIOS. Select USB Flash Drive option and proceed.

Once it opens up the installer for Windows, all you need to do is follow the given instructions. Also, you can use that USB on as many devices and as many times as you want.

So, this was all about the Slipstreaming process for Windows 10. We know it is a bit complex and tedious process but let us look at the big picture, this one-time effort can save so much of data and time for further update installations in multiple devices. This slipstreaming was relatively easy in Windows XP. It was just like copying files from a compact disk to the hard disk drive. But with the changing Windows versions and new builds kept coming, slipstreaming changed as well.

  1. “The only step remaining is to copy the ISO file on a USB drive.”
    A PC can boot from a pendrive with just an ISO file copied in? 🤔

  2. In using NtLite, with the new handy Update feature, is it still necessary to use WHDownloader at all?
    I assumed said NtLite updates feature downloads everything from the offical Microsoft site corresponding to the edition you mount for slipstreaming that it detects. It is also important for readers to know that the WHDownloader no longer works on Windows 7 installations & you will end up with a notice stating as such if you try to use it as I did towards creating a Win. 10 slipstreamed installation; however, a Virtual Windows 10 machine can be used as a workaround for doing everything, though it will be a much slower process overall.

  3. I gave it a go, using it to strip out unneeded Windows 10 versions (everything except Home and Pro), and slipstreaming the latest available updates. Using it is pretty much at least as slow and frustrating as fully updating a clean install of windows 10, except it actually requires more interaction. Even just deleting the unwanted versions was painfully slow, before I even got to trying to integrate the updates.
    I’ve also only succeeded in creating a functional USB boot disk with a single edition of Windows in it (Pro). When I tried to create one with Pro and Home images in it, the result was corrupt and would never finish booting. The one successfull install of Windows 10 Pro I did manage, there was still a large update waiting to be downloaded and installed when it had finished.
    My laptop isn’t that new, but it does have a quad core, 8 thread i7 CPU with over 3GHz turbo core (or whatever Intel calls it) 12GB of RAM and a SSD. Nothing should be as slow as this piece of software. I checked the task manager while it was running, and a tiny amount of system resources were actually in use, so it’s not that it was putting a strain on the machine, it’s that the app needs to be optimised to make better use of available resources.
    The interface is also confusing as hell, if you attempt to download and integrate the latest updates in the way that seems intuitive, it just keeps telling you that it can’t enqueue updates without the licenced version, and doesn’t offer so much as a hint as to how to proceed with using the free version to slipstream updates.
    To top it all off, when I close the app, it gets stuck at 0% cleaning up, then eventually needs forced to close. If this worked well, I would use it all the time, but based on this experience, I think I’ll stick to doing a clean install with the current, unmodified build of Windows 10, and just leaving the updater to do it’s thing whilst I get on with something else.

  4. Thank you for the post,
    I had to install over 50+ Windows 10 OS’s. It did take some time making the USB but saved me hours of clicking Windows update button.
    Thanks again
