Thanks John. Due to a theft I no longer have the software for my main Cad program and don't want to lose it; it's 6 years old but a good one. I found a full version of Windows 7 Home on Ebay from a reputable seller.
I plan to backup my hard drive and upgrade to Windows 7 Home. If I understand correctly, all I need is Windows 7 Home to perform the upgrade. Is that correct?
Thanks,
Adam
