To add Flip3D to the context menu when right clicking the desktop or the background of any opened Explorer window. Save the following code as a .reg file and merge into the registry:-Code:Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Directory\Background\shell\Flip 3D] @="Flip 3D" "Icon"="C:\\WINDOWS\\Explorer.exe,18" "Position"="[B][COLOR=#ff0000]Top[/COLOR][/B]" [HKEY_CLASSES_ROOT\Directory\Background\shell\Flip 3D\command] @="C:\\Windows\\SysWow64\\rundll32.exe DwmApi #105" The "Top"** entry can also be specified as "Bottom" or left blank ("") where it will float in the Context Menu depending on other Context Menu entries. ** If you have more than one entry marked "Top" they will find there own level, but always be at the top. You can change this by changing the Registry 'Key' names though. e.g. aFlip3D, bKillExplorer, cWhatever. HTH.
