Just wanna make sure of something. Currently running the Windows 7 RC, and I would like to ask; can you upgrade to the RTM from the RC whilst choosing which version to install? Cause' I'm currently thinking of installing the Home Premium RTM now, re-arming until October, buy a key and just activate it.
Now I understand to choose a version of Windows 7 to install you need to delete the 'ei.cfg' file. However, I just need to know whether you can upgrade as well.
