Not from Microsoft - there are 3 major players in that dept - one is old, only uses old Windows 200 style bars, another is Realtime Soft UltraMon
which costs like $40 and the third is DisplayFusion: Free Multi-Monitor Desktop Wallpaper Software | Binary Fortress Software
which is both free and shareware (free version is feature limited, but even the limited version packs a wallop in terms of features, including multimonitor taskbar support (although it still uses only a Vista style taskbar) and many other features as well.
I bought the app ($15 CAN, roughly $13 US) and am now helping to Beta test DF on Windows 7 - it is a beautiful app. And, since it is free (you are not *forced* to buy the paid version) I'd suggest you give it a shot. If you like it enough, contact the author about wanting to help Beta test on Windows 7 and buy the software and he'll email you pretty quickly (usually within 24 hours).
