Slipstreaming is basically a process of adding Windows update packages into the Windows setup file. In short, it is actually the process of downloading Windows updates and then building a separate Windows installation disk that includes these updates. This makes the update and installation process more efficient and faster as well. But, using the slipstreaming process can be really overwhelming. It may not be as beneficial if you guys do not know the steps to be performed. It may also cause more time than the normal way of updating Windows as well. Performing slipstreaming without a prior understanding of the steps may actually open risks for your system. Just read this article to know all about How to Slipstream Windows 10 Installation – Tutorial.

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

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

Check all the Installed Windows Updates & Fixes

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

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

Download Available Fixes, Patches & Updates

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

  • First, just download and install the WHDownloader. Whenever installed, launch it.
  • When launched, tap on the arrow button in the top left corner. This will also fetch you a list of updates that are also available for your device.
  • Now select the version and build a number of your Operating systems.
  • When the list is on the screen, choose all of them and click ‘Download’.

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

Download Windows 10 ISO

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

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

  • It will ask if you want to ‘Upgrade the PC now’ or ‘Create installation media (USB Flash drive, DVD or ISO file) for another PC’.
  • Select  ‘Create installation media option and tap Next.
  • Now choose your preferred language for further steps.
  • It will now ask the specifications of your system. This will help the tool find an ISO file compatible along with your Windows computer.
  • Now that you have chosen the language, edition, and architecture, tap Next.
  • Because you have chosen the installation media option, then you will now be asked to select between ‘USB flash drive’ and ‘ISO file’.
  • Choose the ISO file and click Next.

Windows will now start downloading the ISO file for your system as well. When the download has been finished, navigate via the file path and open Explorer. Now just head to the convenient directory and click Finish.

Load ISO data files in NTLite

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

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


  • Now that you guys have installed the NTLite tick the Launch NTLite checkbox and tap Finish.
  • As soon as you open the tool, it will then ask you about your version preference, i.e., free, or paid version. The free version is fine for personal use, however, if you are using NTLite for commercial use, we also recommend you buy the paid version.
  • The next step will actually be the extraction of files from the ISO file. Here you have to head to the Windows File Explorer and open the Windows ISO file. Right-click on the ISO file and choose Mount. The file will be mounted, and now your PC treats it as a physical DVD.
  • Now just copy all the required files to any new directory location on your hard disk. This will now work as a backup if you guys make a mistake in further steps. You guys can use that copy if you want to start the processes again.
  • Just come back to NTLite and tap on the ‘Add’ button. From the dropdown, tap on Image Directory. From the new dropdown, choose the folder where you copied the content from ISO.
  • Tap on the ‘Select Folder’ button to import the files.
  • When the import is complete, then you will see a Windows Editions list in the Image History section.
  • Now you have to choose one of the editions to modify. We recommend you head with the Home or Home N. The only difference between Home and Home N is just the media playback; you do not have to worry about it. But, if you are confused, you can go with the Home option.
  • Now tap on the Load button from the top menu and then tap OK when a confirmation window to convert the ‘install.esd’ file into WIM format appears. 
  • When the image loads, then it will be shifted from the history section to the Mounted Images folder. The grey dot here will turn green, which indicates the successful loading.

Slipstream Windows 10 Updates to an ISO file

  • The next stage here is just to apply all the changes made. It would really help if you switch to the Apply tab available on the left side menu.
  • Just choose the ‘Save the image‘ option under the Saving Mode section.

Slipstream Windows 10

  • Navigate to the Options tab and tap on the Create ISO button.
  • A pop-up will appear where you have to choose the file name and define the location. 
  • Now another ISO label pop-up will appear, just type the name for your ISO image and tap OK.
  • When you guys have completed all the above-mentioned steps, tap on the Process button from the top left corner. If your antivirus shows a warning pop-up, tap No, and proceed. Otherwise, it may slow down further processes as well.
  • Now a pop-up will ask you to apply the pending changes. Tap Yes to confirm.

Whenever all the changes are applied successfully, then you will see Done against each process in the progress bar. Now you are ready to use your new ISO as well. The only step remaining is just to copy the ISO file on a USB drive. The ISO may be many GBs in size. Thus, it will take some time to copy it to the USB.

Now you guys can use the USB drive to install that slipstream Windows version. The trick here is just to plug the USB before booting the PC or laptop. Plug the USB in and then tap the power button. The device may also begin downloading the slipstreamed version on its own. It may ask you if you need to boot using the USB or normal BIOS. Choose the USB Flash Drive option and proceed.
