Windows – How to switch option (alt) and command (windows) keys for Windows 7 in Boot Camp

KeyRemap4MacBook also supports device-specific settings:

<?xml version="1.0"?>
<root>
  <devicevendordef>
    <vendorname>KINESIS</vendorname>
    <vendorid>0x05f3</vendorid>
  </devicevendordef>
  <deviceproductdef>
    <productname>ADVANTAGE</productname>
    <productid>0x0007</productid>
  </deviceproductdef>
  <item>
    <name>modifierkeys</name>
    <identifier>modifierkeys</identifier>
    <device_only>DeviceVendor::KINESIS, DeviceProduct::ADVANTAGE</device_only>
    <autogen>__KeyToKey__ KeyCode::CONTROL_L, KeyCode::FN</autogen>
    <autogen>__KeyToKey__ KeyCode::FN, KeyCode::CONTROL_L</autogen>
    <autogen>__KeyToKey__ KeyCode::COMMAND_L, KeyCode::OPTION_L</autogen>
    <autogen>__KeyToKey__ KeyCode::OPTION_L, KeyCode::COMMAND_L</autogen>
  </item>
</root>

You can see the vendor and product IDs from EventViewer.app. If it can't remap any keys on the external keyboard, try uninstalling other keyboard or HID drivers.

See the source for the key code values and predefined settings.

I know this is 3 months late. But if anyone is still searching, the answer is to use the Boot Camp Assistant to download the drivers. The ones from the Apple Bootcamp website will not work.

If you check out this article: http://support.apple.com/kb/HT5634

Click on the MacBook Air link at the center of the page and you will see:

MacBook Air (13-inch, Mid 2013) and MacBook Air (11-inch, Mid 2013)

need to have drivers downloaded from BootCamp Assistant. So, you will need to boot into your Mac partition and plug in a USB drive and download the drivers.

PS: If the drivers fail to download, make sure your USB stick is attached to the left USB port (the screen facing you). I remember reading it somewhere on Apple's support forum - but cannot find the link at the moment to cite it.

I did this and it worked for me. The Boot Camp drivers installed and I did not get the x64 error message as well.
