I am trying to use Nintendo Wi-Fi and the nintendo wifi usb connector only works for Windows XP. Is there any program(w/o viruses) I could download where I could go into xp mode w/o losing internet speed or, gaming graphics(i play sc2).
Are you saying that you want install XP in addition to Win7 - if yes, you have to buy a license. But before you do, make sure you find ALL XP drivers for your system - that is not obvious if it is a recent system.
You could also try XP compatibility mode, but that does not work on Home editions of Win7.
Try installing the wireless adapter in Compatibility Mode which simulates the program being installed in XP SP2. You can also run the Wizard to find a better mode to try.
The virtual machines recommended here for XP are Virtual Box, Virtual Player and XP Mode if you have Ultimate. Others may know ones more suitable for your use.
You could also try this XP mode of Windows 7 from Microsoft or on your install DVD. It requires Windows 7 Pro or above though:-
Windows XP Mode - Windows 7 features - Microsoft Windows
