I assume all your new computers are same containing same hardware components? if that is the case you could do normal install of Windows 10 and the other desired software first on one computer. Once complete you can create system disk image (system backup) of this computer and transfer/restore the disk image to other computers. Another method is to clone the system disk. The cloned disk can then be installed on target computer. There are several SW tools to do either option. Some that come to my mind are Partition Magic and Easeus Todo. In some cases HDD and SSD manufacturers provide free SW tools to create or transfer system images. Obviously you still need to get windows 10 licenses to each computer and activate them on each new computer manually.
