Reports from the field indicate that MagicJack works with Windows 7. Here are some selected quotes:
Yep, can confirm MJ works with Windows 7 on the Release Client and more recently the retail version. No issues. I’m running a stock MJ out of the box.
And another:
I just bought Windows 7 and put it on my laptop and it works very well. I never had any real issues using magicJack with XP and or Vista and for me it seems to work even better with Windows 7.
So no worries with Magic Jack and Windows 7.
