Hi,
I done something similar some years ago when using only the regular virtualdub x86 & x64, not sure if it was exactly this reg edit but it was a registry modification, later started to use the exe re-compile method ( as i also sometimes can change the icons used by the exe's at the same time ), using this last method for various little tools customization since a few years now.
This said i noted it and will keep your method in memory for the next time i will need it
Thank you.
