Of course you can upgrade RC1 to RTM for Windows 7, except when you are running different versions of Windows…. but of course…
After browsing a bit I figured out that the switching between Windows 7 versions can only go in one direction: up. So when I installed Windows 7 RC 1 to replace my broken Windows Vista installation, I didn’t know which version I would get when the RTM was released so I did what everyone did: install Ultimate.
Fast forward 6 months and I am starting to miss the fixed features from the final version which us poor testers will not receive unless we go for the full monty and get the paid version.
So here I am, downloading all my programs and drivers again, hoping I am not forgetting a key component and just finishing my system backup in case things don’t work out as planned…
On a side note: I am doing this on a Dell XPS M1530 which came with a 32-bit version of Home Premium and which does not officially support Windows 7 (32 or 64-bit). Unofficially, everything works like a charm on Windows 7 RC 1 (build 7100) including the webcam, fingerprint scanner and the Intel 4950AGN card. I will report if the reinstallation to the final version went as flawless as the original installation.
