Check out this nifty little program from Long Zheng and Sven Groot: Windows 7 ISO Verifier, for your downloading pleasure - istartedsomething
It's called ISO Verifier and quickly tells you whether that lovely new Windows 7 ISO you happened to *find*
Basically what everyone does with HashTab but automated.
Some of you might have already seen this but nothing turned up when I searched on here.

Should support the RTM build when it arrives.
