I bought a Mini-pc with Windows pre-installed and I would like to retrieve the product key for this machine as I wish to install a Ubuntu and then run windows in a virtual machine with this license. It seems as though the product key is not installed in the BIOS. Please help?
If that doesn't work (and it didn't for me), NirSoft makes a freeware tool, called ProduKey, that will summarize the available key information. You can download it from here: https://www.nirsoft.net/utils/product_cd_key_viewer.html.
