Thank you for your great proggy! I have however the problem that I installed Windows 8 at drive D:! And now Aero Glass Tweaker GUI for Win8 v1.1.6 doesn't work: it says: Cannot find ... at C:\DWM... Is it possible to customize the HD to which it must be addressed to? Something like an .ini-file in which it is possible to change the default C-drive to D-drive? That would be great! Hope that is possible! EDIT: Meanwhile I found a workaround: I just copied the DWM-folder to my C-drive, and that works! But it would be nice, of course, to have the opportunity to choose the drive at which Windows 8 is installed on.
