When I built my current computer, I purchased the Original Equipment Manufacturer (OEM) version of Windows 7 64-bit home edition, as it was less expensive than the full retail version of the same program. However, at that point, I had not conducted as much research as I should have, as I later learned that the OEM version of Windows 7 is tied to the motherboard of the first computer on which it is installed, meaning that all other hardware upgrades are allowed, but not motherboard upgrades. This is a problem for me, as I plan to eventually upgrade many components of my computer, including its motherboard, at some point in the future, and I do not wish to spend more money to get a new version of Windows 7 when I could have done that from the very beginning.
I noticed that the only thing that indicates that my operating system is an OEM version is the presence of the letters "OEM" in its product key. If I change its product key, will it no longer be considered an OEM system and thus no longer have the restrictions of such? However, if there is no way to bypass this problem, and I must purchase a new version of Windows 7, can I install it over my current installation of Windows and not lose any data or settings? I hope so, as it would be a major hassle for me to reinstall all my programs and customize all the computer's settings to how I have them currently. Finally, why does the OEM version of Windows 7 have such a restriction? I cannot understand what reason thee would be for placing such a restriction upon the system.
If anyone can assist me with this situation, I would be most appreciative for the help.
