Where do I obtain Windows 7 64-bit drivers for the Apple Wireless Keyboard?

Question

How can I install Apple Wireless Keyboard on Windows 7 x64 running on a non-Apple hardware?

The operating system does see the keyboard but it doesn't want to pair with it at all.

Answer 1

For pairing I had to reset keyboard memory by powering it down and powering it on by keeping the power button for more than 3 seconds.

For drivers, required for Fn key ussage, check http://superuser.com/questions/88912/does-apple-magic-mouse-fully-work-on-windows-7-x86-x64

Answer 2

After 3 frustrating hours of trying every tip on the net, I found the answer: Try this:

This finally fixed it for me: Device Manager - Open System Devices, you will find a Bluetooth HID Device. Double Click it, open Driver tab and click "Update Driver" Select Browse my Computer, then "Let me Pick". It should now show TWO compatible drivers with exactly the same name. One of them is the Microsoft one, one is the non-working Chinese **. Install one of them and see if the driver properties changed to the right (Microsoft) driver. If not, try again with the other one. For me, the Microsoft driver was the first one in the list, but this may be different for you. Wow, an annoying and intense hour of trouble shooting finally over...

The issue is related to the Chinese version of the driver that the latest Windows Update applies, and stops the keyboard from working.

I'm finally able to type this using an Apple Wireless Keyboard on my Windows 7 64-bit PC!
