I use the RTM and I was told by my it that the keys won't be ready till Mid October so when the Retail comes out how do you upgrade without doing a fresh install?
Hello and Welcome to Windows7forums..
Though your question is a tad confusing, it's certainly not unanswerable..
The short answer is no you can't "Upgrade" in the sense of the word.. That is, the RTM IS the GA.. The code is identical because both are the same thing.. It's not like going from the RC to the RTM.. In that case, your dealing with two different sets of code..
In summation, you can't Upgrade from the RTM to the GA.. You can purchase the Upgrade media and use the "Clean Install with Upgrade Media" trick but a direct Upgrade isn't recommended...
