[solved]Just a silly windows 7 question

Does windows 7 automatically install drivers? Because it is running at 1600X900 and has already detected my 9500gtx.
Answer #1
Yes, I think so.
Answer #2
Installs generic drivers, if you give it access to Windows Update and if your gfx card manufacturer put drivers out there you will download through Windows Update and thus have drivers automatically in a way.
Answer #3
It does for some, and some it doesn’t.
Answer #4
Alright Thanks for the replies guys
