I pretty much wasn't even thinking of reusing my OEM windows XP product key from my dead 8 year old HP PC, and I was asking about Belarc advisor, product keys, etc., because I read a suggestion in this thread here from wizardfromoz. At first I didn't know about Belarc Advisor until Wizardfromoz mentioned it.
I saw wizardfromoz's suggestion about a way to re-use the OEM windows XP product key on a virtual machine inside a different PC, even though most say it is impossible, much less illegal to do so. I had a hunch that Belarc Advisor only shows PC specs and product keys and all that stuff, but when I tried using Belarc Advisor, I found out that you must Boot into the operating system in order to check out that specific PC's specs and product keys, meaning that even though wizardfromoz thinks that Belarc Advisor is useful from that discussion, in reality it is actually not, considering that I have an OEM copy of windows XP tied to a dead motherboard, meaning I can't boot that PC to run Belarc Advisor, and that OEM copy of windows XP won't boot anywhere else.
I know he was trying to help, but I am not willing to try any suggestion that makes me cough up cash to buy a certain piece of hardware, and if there is a remote chance of the suggestion being illegal in some way, I am not going to try it, which is why I was asking wizardfromoz how he did it, because maybe he found a legal way to do it, or some sort of loophole. As for me, I am not going to risk it. I wasn't that high risk high reward kind of guy anyway.
