When I install Windows 10, which keys are preinstalled ?
You can retrieve the product key of your Windows with for example the following third party tools:
On standard Windows 10 install media, look for the file \sources\product.ini. It contains many generic Product Keys used by the various Windows 10 Editions that are available. Most installs will show one of these same generic Product Keys if you use a utility, such as Nirsoft's ProduKey, to reveal the current Product Key for your Windows 10.
The keys listed in product.ini will not activate Windows unless the specific device already has a digital license for Windows 10.
Thanks in advance.
For iso AIO by Adguard has "product.ini", while iso from MS (for example from MSDN) does not have "product.ini" available.
I am still blind !?
I have noticed that some ISO files contain this product.ini file and others do not. For example, if you build a version 1909 ISO file using the Media Creation Tool, it does have this file, but if you download the complete ISO file directly from Microsoft, it does not contain the product.ini file.
Still, as long as you can find a copy of this file, the primary generic Product Keys (such as for Windows 10 Pro, Enterprise, Home editions) do not vary from version to version of Windows 10. They have remained constant since 2015.
