With a retail license, the license is not tied to one computer, and can be moved to another should something happen to the current computer. Switching to a retail license won't "upgrade" anything. It will be the same, accept the OEM license will no longer be in use and the retail license can't be used on another PC, should you decide to build/upgrade/downgrade another one.
I'll ask the same as Addram. Are you actually experiencing an issue with your current Windows 7 install?
