virtualbox.org

Using Disk2vhd I made an image .vhd of my actual OS win7 64bit Enterprise on the network.
Then I convert it to a .vdi image with : VBoxManage clonehd source.vhd target.vdi --format vdi
It was long but successful.
I created a new virtual machine, I started it, changed it's name, restarted it.
It's all great EXCEPT the activation is lost, Is there a way to get my actual OS activation to keep it to the VM ?
Tools like "Advanced Tokens Manager" or "7tokens manager" don't work...
I guess it's because it must be a volume licence, I am not administator of the firm, just of my computer...

Is there any way between the regedit and/or some key file that I could activate my VM (I don't have access to Internet with my computer, I must go through others) ?
As anybody ever tried something like that (Enterprise licence) ?

You can't re-use the license per say, you must re-activate or contact Microsoft support. This is a normal behaviour, and follows Microsoft licensing terms which is one activation per machine (be it physical or virtual) and any "big" hardware change will trigger it (from Windows point of view, you effectively changed the hardware underneath).
