William,
It is still okay to install Windows 7 however you will not be able to
experience the benefits of Windows Areo. Also,
Microsoft does have an official Windows 7 Support Forum located here
'Windows 7 Category' (http://tinyurl.com/9fhdl5) . It is supported by
product specialists as well as engineers and support teams. Should you
run into any further issues, you are welcome to seek assistance there as
well.
