It's definitely still true. Every windows install from a non-OEM copy in the last few years has required me to sneakernet my network drivers before I could do anything (including get other drivers). Linux has actually been much better for this since the release cycles are shorter and the barrier to getting a driver officially included seems lower (requires WHQL certification on windows, which presumably is not only work but costs money).

It's actually been quite a while since I've had to do the driver hunt for Linux, but it's been routine with windows (unless you use the default oem install, obviously).

I guess one thing Windows does well is pulling drivers from Windows Update. So if your network card is supported there is a good chance you'll get things working. Unfortunately not every network card you can throw at it will work out of the box.

Pretty much every time I install windows (only for the games) the first step is to boot into linux, download a windows driver for my network card, then boot into windows to install it so I can start downloading other drivers.

Depends a lot on your hardware. I've had the most problems with network drivers. With 7.

I think that is also partly because XP lasted a very long time.
