I installed experimental 64-bit debug build for 10041 this way. Maybe someone finds it useful. 1. Installed http://www.glass8.eu/files/setup-w8.1-1.3.1.exeto default C:\AeroGlass folder. 2. Closed task aerohost.exe and then renamed C:\AeroGlass to C:\AeroGlass1 3. Rebooted. Copied contents from http://www.glass8.eu/files/10041-64.7zto C:\AeroGlass1 4. Renamed C:\AeroGlass1 to C:\AeroGlass 5. Rebooted. 6. Done, with dwm.exe running in the background. The taskbar is not transparent, unless I use the posted .vbs script.
