Hello all Win7 Gurus. I've been running Win7 RC since it was released and am very happy with the OS. I have now received my Purchase of Win7 Professional (Upgrade via retail internet purchase) and am wondering how to proceed. My PC is running a dual boot of Win7 RC and WinXP. I have not installed the Win7Professional and am wondering how to proceed. Thanks in advance and cheers and beers to all.
