Hello,
I have bought new computer and generated new license. Few days later I did activation of Windows (because of downgrade from W8) and after activation the ID have changed. I think it is not good that the ID depend on Windows activation.
[RESOLVED] Changed ID after Windows ativation
Re: Changed ID after Windows ativation
In most cases it won't happen. In the case that there is not a valid motherboard serial number, I fall back to another factor that does in fact change like you said. Sure, it's not good. I am open to suggestions for more stable machine identification.
Re: Changed ID after Windows ativation
I understand that find best way is not easy. Maybe some kind of CPU serial number will be enough? I dont know if each CPU has any unique identificator.
CPU is changing only if you make upgrade. But for example hdd fail or Windows reinstall is more usual.

I think I just got bitten by this, and had to create a new license ID.
Is there a way I can see if my PC/BIOS returns a serial number?

Get this and run it in a command window:Uxorious wrote:I think I just got bitten by this, and had to create a new license ID.

Re: Changed ID after Windows ativation
Looks OK. If your ID changes again, run it again and we'll see if it changed. Theoretically it should be stable but with Microsoft, who knows?
Re: Changed ID after Windows ativation
Yes, I also came across this .. When I have changed edition of Windows (from Home Basic to Ultimate), I'm again made a new lisenсe.txt..
Re: Changed ID after Windows ativation
If would help to see the output of the linked utility before and after.

The latest licensing method is stable across Windows versions. Marking resolved.
