The theme is dark, but designed to still be fully useable in day to day work, and to that end retains a light global window background (e.g. in documents etc).
YADS is fully compatible with both 32 and 64-bit Windows 7 (I have extensively tested it on both platforms).
INSTALLATION: Installation does NOT require replacing aero.msstyles. It can be activated/deactivated using "Personalization" in the control panel, so you can easily switch themes if you don't like or tire of this one.
I have also included some complementary Windows resource files (both 32 and 64 bit versions), but installaion of these is entirely optional (instructions included in the archive).
KNOWN LIMITATION: In a handful of apps the toolbar text is black, and therefore almost impossible to read. These apps, for reasons only known to their developers, use the global Windows Text color for their toolbar text. Since I want black text on light backgrounds in documents, this cannot be fixed. However, if the app is skinnable (and a lot of modern apps are) this issue can be easily addressed by applying an appropriate skin to the app.
