This example uses a Hyper-V Generation 1 virtual machine ( VM) as the technician machine, with a 64 GB virtual hard disk. Windows does not need to be activated for this process. When the desktop requests a product key, select the "I don't have a product key" option. Install Windows normally until it stops at the Region Selection screen after the last reboot. You should follow these steps to create a custom ISO for a Windows 10 desktop.

Using this customized ISO for your installation media, you need half an hour to clean install Windows 10 with all your software and personalization. First, you should install Windows 10, customize it to your needs, install all the software you need, capture that installation and use it to create an ISO. There is a different method you can take.

Then, you'll need to repeat this process for each of your PCs and repeat that procedure whenever a reinstall is necessary. You'll need to install software and the desktop and personalize the Start menu to meet your requirements.

In 15 to 30 minutes, you'll have a clean, fresh Windows 10 installation, but it still will require some work before it's ready for production use.
