How can I add my product key permanently to a Windows 10 install USB drive?

Question

Good evening,

I am trying to activate a Windows 10 IoT Enterprise CBB install permanently with its license key by using the DISM tool.

I have found this topic which explains how to do it (mounting the install.wim, setting the product key and unmounting the install.wim). I am doing the same steps, however when installing Windows to a drive, it still prompts me the Product Key dialog box also with EULAs.

My product key is valid and the purpose of this operation is to install my Windows 10 Edition in "one-shot" which means without typing any license key or accepting any EULAs since they would have been already typed/accepted.

(I am using a bootable USB drive in UEFI)

Solution

Use notepad to make a file called PID.txt and put the following in the file:

[PID]
Value=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

Place your Windows 10 product key in where the X's are and save the file to the /sources directory of your Windows 10 installation USB flash drive.

Additional sources include Microsoft support for this very process: https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/windows-setup-edition-configuration-and-product-id-files--eicfg-and-pidtxt

Apart from the answer below you may also need to look at using an unattend file if you expect to have an automated installation.
