For a lot of Maximum PC readers, the fuss over Windows 7 launch week might seem a little unwarranted—after all, many of you have been happily running Windows 7 for months now, so what’s so exciting about a retail launch? In fact, if you’re in that boat, the launch poses more of a hassle than anything else, since your free RC version of Windows 7 is closer than ever to shutting down. And when it does, you can't even do an upgrade install of Windows 7, you have to either re-install Windows Vista first, or buy a standalone version of Windows 7.
Or do you? Even though Microsoft’s official stance is that you can’t upgrade from the Release Candidate to the RTM/Retail version of Windows 7, it’s actually possible to do so using a quick, easy hack. This means that you can use the cheaper upgrade version of Windows 7, and do a "Custom Upgrade" to get a clean install. Or, if you don't mind the risk of additional headaches down the line, you can do an in-place upgrade from Windows 7 RC to RTM.
