Silent Aero Glass
Silent Aero Glass is a little utility I wrote that prevents the annoying demo version message of Big Muscle's Aero Glass for Windows 8 from popping up. At the moment it only works on the 64-bit version of DWMGlass. Feel free to modify it for 32-bit if you need it.
If you don't trust the pre-compiled binaries I provided in the download section get Visual Studio 2010/2012, clone the source and compile it yourself. Make sure you use Visual Studio 2010's compiler (even if you're on VS2012).
Also, this dll can be modified to suppress any kind of messagebox system-wide on x64 systems.
This software does not modify bigmuscle's software in any way, as it merely hooks MessageBoxW system-wide, so it does not violate any kind of copyright.
