I have on one of my comps installed Windows 7 RC build 7100 I believe.. I was wondering, so as to avioid going thru the whole uninstall(maybe) and re-install process again, if I were to input a valid reg. code or serial would it then magically convert to the full retail (pro, ultimate, whichever).. Is there even and option TO enter a serial in the RC versions?? You'dve thought M$ would have imbedded that option that way the program is already installed on the masses computers all has to be done now is DL the "full" version, patch, and of course $$$ for the serial #. Anyone know what the deal is on this? Thanks,.
