Here's a blog that talks about solutions someone came up with for Apple keyboards in Windows:
(p.s. google: apple usb keyboard on windows)
Googling got me to this page, which mentions that there are specific mappings when I have installed the Apple Keyboard Support driver.
The page you linked to mentions I should download bootcamp and extract the drivers. I'd like to do that, but of course Apple don't have a bootcamp download any more (at least, the one mentioned in that article). It seems like it might be an appstore thing, and there is no app store on Windows, so how do I get the one teeny little driver that Apple have made already, since they don't have a download for it? Out of bootcamp's driver disk, which is ... where? Many sites mention that it is part of the bookcampesd.pkg file, which used to be located at:
but is no longer available. Where do I get BootCampESD.pkg from, this sounds like it has the stuff in it that I need. The bootcamp page on Apple does not mention the ability to download bootcamp...
I guess the solution is going to be: 1. Buy a mac. 2. google for hours to find the bootcamp download since it's not on the obvious "download" link on the bootcamp homepage (no, that contains java updates). 3. Google for hours to find the bootcamp download again because the last one doesn't work. 4. Repeat steps 2 and 3 twelve more times. 26. Install bootcamp. 27. Extract the driver & copy it out. 28. Put it on Windows. Hooray!
I fully realize that you are not using BootCamp but that forum may be more helpful compared to this one. This one is for pre-1997 Macintosh computers and gets very little traffic.
Maybe someone in the BootCamp forum has a similar experience; it's a long shot, just not as long as posting in a forum for Dino-Macs!
