Apple Keyboard on PC (Vista and XP)

It will work with the exception of the special function keys on the top row like brightness, volume etc...

How did you get it to work? My keyboard isn't "discoverable".

I just bought a compact aluminum Apple keyboard to use with an external monitor on my Dell Latitude E6500 laptop running Vista at work. I use a MacBook at home and wanted similar keyboards in both places. I used the free KeyTweak program to disable Caps Lock (my personal preference) and to turn the Apple Command keys into Windows Ctrl keys. KeyTweak makes its changes in the Windows registry. I used the free AutoHotKey program to run a script that gives me Home and End when I press Ctrl-Left and Ctrl-Right, PgUp and PgDn when I press Ctrl-Up and Ctrl-Dn, and forward Delete when I press Ctrl-Delete. I do Ctrl-Alt-Del on the laptop's keyboard when I need to. (Although KeyTweak was able to change the Apple Control key to a forward Delete that worked for the Ctrl-Alt-Del combination, I chose not to keep this particular remapping.) I use the PrintScreen key on the laptop. Altogether I am a very happy camper now. Here's the AutoHotKey script to get you started:
^Left::
Send {Home}
return
^Right::
Send {End}
return
^Down::
Send {PgDn}
return
^Up::
Send {PgUp}
return
^Backspace::
Send {Delete}
return

I'm in a similar position. Bought an alu keyboad (wired, without numeric keypad). Problem is that the PC won't recognize the "AltCtlDelete" key command to get to the Windows log in window. Any suggestions on how to work around?
