According to the amazon review (the first one) you can install the Macally to windows.

But it doesn't seem to be working for me. I plug in the USB and it says, "Windows does not recognize device" or something of the like. I troubleshooted and it says unknown device--the port is fuctioning, the driver just needs to be installed. But the CD that comes with the keyboard which contains driver installation doesn't seem to work on Windows. It seems it opens with a program that only Macs have. I got my computer in 2003, and USB mice seem to work on it. Please help.
