You CAN install the driver, but you'll have to do it manually
you'll need to download a .cab file from Microsoft update catalog website using internet explorer (ActiveX), then install the .inf file using device manager
instructions and links at xbox support website
http://support.xbox.com/en-US/xbox-on-windows/accessories/connect-xbox-one-controller-to-pc
you'll find the links under "Windows 7 and 8.1" (you can ignore that they said it's for 7 and 8.1 only)
I approve that it works, I did install it on a Windows Vista laptop
