How to install Vista Drivers on Windows 7
If you are nervous about testing your copy of Windows 7 because you are not sure what to do as far as device drivers 
are concerned, here is some news for you. Windows 7 is essentially the same as Windows Vista and as such Vista drivers will work just fine.
Go to your hardware manufacturer’s website and download the latest drivers available for Windows Vista.
After downloading the drivers, run the installation setup and follow the prompts. If you are presented with any errors due to compatibility, cancel the installation, right click the on the install package’s .exe and choose Troubleshoot Compatibility. This will present you with a “Program Compatibility” wizard of sorts, which is friendlier than on previous version of Windows.
The wizard will display a few common issues to select from and ask which apply to your situation. You will not be able to proceed without selecting something. If it’s not already there, just check the box next to “The program worked in earlier versions of Windows but won’t install or run now” and click next. We will want to choose Windows Vista as the last known OS to support the drivers.
Once completed, there should be a window displaying the new settings enabled for your software and the option to test your new configuration by click next.
