I'll save BigMuscle the trouble of answering... Drop shadows come from the theme resource list. Windows is currently compositing fully transparent drop shadows for you. Nice of them, eh? You can add drop shadows yourself by having Aero Glass for Win8 load alternate desktop element resources from a PNG file, the path to which you specify by the HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM : CustomThemeResource REG_SZ value. Click here to download the alternate theme resource PNG file I've modified. -Noel Thanks for this! But I'm asking for something else- if bigmuscle will sell his aplication (even He don't know it), 'drop shadows' option could be nice addition. If it will be freeware, I won't grumble. It's just an idea to make his work even better Another idea is adding some 'space' to taskbar and window bar, I mean now they are flat , but have blur and transparency. Adding some 'shine' on the edges of them have some sense (for me). Just like here: http://globalknowledgeblog.com/wp-content/uploads/2010/07/windows_7_aero_peak2.png BTW: Now, finally I can run v.85version, with normal transparency and blur (Opacity 50, Blur 60, dx9.3)!
