I wonder how this would work relative to Microsoft's 'genuine' services. I remember having a whale of a time on XP. Our officially purchased Japanese CD of WindowsXP got "caught" as a non-genuine product by Microsoft.
I assume the same/similar risk exists here for this user.
If you purchased the legal copy, and it doesn't work. Then a official agent uses a illegal copy and activates your account. Then you login to a microsoft account. Do you risk losing your entire account due to a TOS violation?
