can you use the windows 7 upgrade if you have Windows 7 RC Build 7100 installed

@protozee:No. You must have a "qualifying" version of Windows installed (XP or Vista).@kevpan:(1) I'd have purchased a 7 Prof upgrade for $99 and upgraded later by "Windows Anytime Upgrade". This would have saved you ~$100.(2) Seeing is believing (RTM release).Mobile AMD64 3000+, VIA Apollo K8T800 chipset, 1 G RAM, ATIRadeonMobility 9700, 20x DVDRW, C:XPSP3 (55G),D:WIN7 (25G),F:DATA (250G)

What does it matter what is the last day is you can download? You can do a clean install to the Windows 7 Pro from the Vista ultimate just need to back up all your data first. If you are using Win 7 RC already you are going to need to do a clean install anyhow.Tim Comes
