I was running Vista HP and planned to upgrade to Windows 7 Pro before I realized it would require reinstalling programs. So I called Microsoft and cancelled the Windows 7 Pro order and purchased Windows 7 Home Premium Upgrade locally. But I'm having problems running all Call of Duty games with hard crashes.
Meanwhile, Windows 7 Pro Upgrade arrived in the mail despite my having cancelled it and I found that indeed, Microsoft billed my credit card. Now, I've a mind to install Windows 7 Pro on my desktop and just do the resinstalls, and then use the copy of Home Premium Upgrade on my laptop. I'm sure I'll have no problem running COD in virtual XP mode on Windows 7 Pro.
So, a couple questions:
- To install Windows 7 Pro, I assume I have to first install my earlier version of Vista? Can I do that if it's already "linked - if that's the correct word" with the Windows 7 Home Premium upgrade I've had in place for a couple of weeks and is registered?
- Can I then install the Windows 7 Home Premium upgrade on my Vista HP laptop, despite that it has already been registered on the desktop? Or do I need to call Microsoft?
(I hope this makes sense.)
