If so, almost all netgear wireless adapters won't work as this isn't supported.
If your still using the 32bit version it will still work just like Vista or XP.

Compatible for Win7 is much higher than that of Vista, and can support most WinXP and Vista software and drivers. Netgear doesn't have 64bit driver support (if going from 32bit to 64bit you might have some replacement driver issues). Win7 however will not allow incompatible drivers to be INSTALLED which might make it unstable. If it's not supported or for GAMING purposes, you might want to go wired if possible. Quote
