Hello, I have a somewhat interesting situation. I'd like to upgrade from Windows 7 pro 32 bit to Windows 7 pro 64 bit. I already know how to do a clean install, and how to back up all my important files like photo's etc. What I don't know is how to get the "upgrade". I heard from someone that I can obtain a 64 bit version of Windows 7 pro with a "re-license" of sorts from Microsoft if I already own a license and a copy of Windows 7 pro 32 bit. All for essentially the cost of shipping. If this is true, can someone point me to how to get that disk. If that turns out to be bogus, would I have to buy a full new version of Windows 7, or a certain type of Upgrade, basically making my previous purchase of the 32 bit version unnecessary and somewhat wasteful. Thanks for any help.
