I've not upgraded to Win7 yet (its on my Christmas list, so I don't want to buy it myself).

I did find this utility handy for symbolic links in Vista.
There is mention of Windows 7 in the history section of the site.

The program was virus free when I used it.
But I'd recommend you scan anything you download.
