Hi Pauli. I'm a bit surprised by your response. You are correct that violating Windows licensing rules is a copyright violation. However, there is not enough information in my post for you to tell whether I violated MS licensing rules or not. Also, changing disk id's is not illegal.
In my case, I had a failing computer (it is no longer in use) that I used Symantec's SSR Recover Anyware feature to recover to a new machine with different hardware than my original machine. Other companies like Acronis have the same feature that allows you to recover to disparate hardware. They are very upfront that recovery to disparate hardware does not circumvent Windows licensing. My reason for doing the Recovery Anyware is simple: I didn't want to have to do a fresh install of Windows and then reinstall all the software on my new machine. I had literally hundreds of programs installed, all of which had configuration information, etc. etc. I have had to do this in the past and that is no fun.
In fact I was fully prepared to purchase another Windows license, so I was surprised when the machine booted up with no licensing issues after the recovery. I had actually done a bit of work with MS to determine the best way to handle the new license. I don't remember an option during the recovery asking me to keep the same disk signature but it may have been worded differently. This is the 1st recovery I've ever done to disparate hardware. In any case, if I had it to do over again, I would want a different disk signature so as not to deal with the problem in this post. Not sure if a different disk signature would have required a new license or reactivation. Don't know all the MS licensing rules for activation. I did not have to reactivate after the recovery. Just booted up and ran. Hell, I've had to reactivate Windows in the past for minor hw changes on the same machine.
And the other machine is retired, used for parts, one of which is the old system disk that I'm trying to use on this machine as a data disk. So I'm only still only using one copy of windows. And I could have done the recovery using the old system disk; just chose not to.
