Can you install OS on multiple computers simultaneously?

“We use industrial PCs running windows with our software to control machines we sell. The PCs are identical hardware. How would we go about creating an image to use on each so we don't have to go through the windows install, drivers, and our software install each time. How do we handle the unique windows product id/key?”

Like the above case, there may be many small, medium, large enterprises that want to deploy image to multiple computers and have similar questions. Here, I’ll explain in details.  

For the first question, you could use a trust and reliable backup software and image deployment software that can help you install OS on multiple computers without reinstalling one by one. And the computer must be in a same LAN.

For the for the second question, if you are using a Retail product key, you could use it on multiple computers. However, it’s not legal and you are not able to activate more than one computer with installed Windows. Thus, you’d better to buy extra product keys if you have many computers.

Need a trust and reliable backup software and image deployment software

To install operating system on multiple computers, you need a backup software and image deployment software. I highly recommend you AOMEI Backupper Standard and AOMEI Image Deploy.

AOMEI Backupper Standard is a trust and reliable backup software used in the worldwide. It can help you backup system or disk in a very short time.  And it also provides you extra features, such as, daily, weekly, monthly backup, event-trigger backup, incremental or differential backup, and so on.

AOMEI Image Deploy is a FREE image deployment and network cloning software that supports deploying or restoring an image to multiple computers over network. And here are advantages of it.

  • This software is free and easy to use.

  • This software supports dissimilar hardware restore, for example: CPU, motherboard. 

  • This software support multiple operating system, including Windows 7, 8, 10 and Server 2003, 2008, 2012, 2016, 2019.

  • The server machine can monitor the process in real-time.

  • The server machine can batch preset client computers name and IP address.

Example: Install OS on multiple computers simultaneously

Preparations for installing Windows 10, 8, 7 on multiple computers at once:

  • Select server computer and make sure all computers on the same LAN. Server computer need to be a fully functioned machine with Windows system.  

  •  Ensure the Windows Recovery Environment (Windows PE) of server computer is complete. If it is incomplete or the system is older than Windows 7, please download Windows AIK/ADK.

  • Confirm the network card of client computer supports network boot (PXE boot).

  • Set the network boot as the first boot device. Start all the client computers and enter into BIOS by clicking the specific key (usually F2 or ESC), go to “Boot” tab and press “+” to move “network boot” to the first option.

  • Download AOMEI Backupper Standard and create a full system image. To deploy image to multiple computers, you need to create a system image first. Without image, you can do nothing. In addition, you need to put the image on NAS or network share folder, which is on the same network segment of the same LAN as the server computer.

Detailed steps to install Windows on multiple computers at the same time

To install Windows on multiple computers with identical or dissimilar hardware, use the following steps. Here, I will take Windows 10 as an example.

1. Free download, install and launch AOMEI Image Deploy.

2. Create bootable WinPE ISO file for client computers. Select “Create WinPE automatically” or “Create bootable WinPE ISO manually” and click “Next”.

Bootable File

Tips:To deploy image over network, there must be a DHCP server in your LAN. If no, please tick the checkbox before "Enable DHCP".

3. Use WinPE ISO file to boot your client computers. Once AOMEI Image Deploy shows "The service has started, waiting for connect...", start all the client computers from network boot and wait for all the client computers to boot up successfully. Finally, you will see your local IP address and connection status on the client computers.


4. Then tick the checkbox before “I confirm all the client...” and click “Next”.

5. Specify the image files and configure the deployment settings. Just click “Browse” to find you image files saved on network share or NAS, then manually type the number of deployed computers every time, select the online computers you want to deploy image and click “Start Deploy”. Here, the image file is Windows 10, deployed computers are 10 everytime.


6. View the image deployment progress in server computer and wait.


Tip: You can choose whether to shut down or restart the client computers after the deployment is completed.

Written in the end

To install OS and software on multiple computers, you need to create a system image backup with a trust and reliable backup software like AOMEI Backupper, then use image deployment software to clone Windows 10, 8, 7 to multiple computers at once. The most important thing is that AOMEI Image Deploy this feature can solve your worries and avoid boot failure after deploying. Because it support dissimilar hardware restore.
