Windows License when running a virtualized Windows on a linux host



I am a new happy owner of a Carbon X1.   I have installed debian and after some configuration tuning, it runs fine.  


I am mostly a Linux and Mac user.    From time to time, I need to run a app in Windows or Mac OS so I am thinking about running one or the other in a virtual machine.  I am wondering now if I could use the Windows licence key associated with my Carbon X1.    Where is the license key? It is not on a sticker under the device.  I have read on some thread, the key is written somewhere in the hardware.  Is there some way I could use that key ?

Re: Windows License when running a virtualized Windows on a linux host

On my X1Carbon 5th gen I could get my Windows key with:


$ hexdump -s 56 -e '"Windows License: " /29 "%s\n"' /sys/firmware/acpi/tables/MSDM


However, if this is valid to use in a virtual environment or not - I don't know.

Re: Windows License when running a virtualized Windows on a linux host

I have the same issue, posted elsewhere but fear Lenovo support may not watch "Solved" topics ( - apologies for the repost)


I have a brand new X1 Carbon 6th generation and need to install Ubuntu 18.04 on it. As it has Windows 10 installed (and thus I own a copy of Windows 10) I would like to create a VM (under Linux with VirtualBox) to run that Windows 10 so that I can test websites in Windows when necessary.


So I don't want dual boot, nor do I want to run Ubuntu in a VM under Windows. I just want to run one copy of Windows, but I want to run it in a VM under Linux.


My "old" machine - a T520 - came with the Windows license key under the battery. I hear that the current license key is in BIOS, but that likely won't be accessible from the VM.

  • How can I install a legal copy of Windows 10 - pre-installed on the X1 - into a VM?
  • Where can I find the XXXXX-XXXXX-XXXXX-XXXXX-XXXXX key?

I am downloading the recovery USB from Lenovo Digital Download Recovery Service (DDRS). Does this include the Windows License Key and allow installation in a VM?


Or if I start fresh ( where do I get the License key?
