How to verify if win 7 upgrade is legal

[BILL1909]

Is there a number I can call at MS to see if my win 7upgrade is legal.Would like to do this before I try and install.Its sealed in a box and says upgrade for win Vista (I have XP PRO).

Win 7 upgrade to new h/d

I have xp pro installed on disk that might be going.Will be installing win7 upgrade on new hard drive (2ter H/D,3 partitions). I understand that I have to put in a xp key code to get it to work.Can I use the xp code from another retail copy of xp.Meaning after install win 7 I will connect old h/d with xp (do not want to use that key code) and try to dual boot.
My old drive has xp as C drive. I believe with the new win 7 I will be able to put any dive letter I want. It should not affect a dual boot system.

Hello Bill,

If it's a retail upgrade box from a legit retailer, then it'll be a legal copy of Windows 7.

Technically from the EULA, you only qualify for the upgrade copy of Windows 7 if you are upgrading from Vista. Otherwise, you would need to purchase a full copy of Windows 7 instead.

Hope this helps,
Shawn

If memory serves me you won't be asked to enter the XP product code as verification. Windows 7 will look for the installed qualifying OS during install. If there isn't one it won't install.
