TO USE: Choose the .reg file you want to convert and hit Upload.
The next page will verify it uploaded successfully, and give you a couple of options.
When happy, click Convert and Download XML and you should get a prompt to download your XML file.
TO APPLY: Copy the file to your clipboard (just find the file, and either right-click -> "Copy" or select it and Ctrl+C)
In Group Policy Management Editor, under Computer/User Configuration -> Preferences -> Windows Settings -> Registry, right click anywhere in whitespace and click "Paste"
The settings SHOULD then be imported directly as collections of Registry settings. Hopefully.

If you're messing with this sort of stuff, I expect you to know what the hell you're doing. Don't blame me if it breaks.
On the other hand, if you think I'm awesome, you are welcome (although not obliged by any means) to buy me a beer :)
