Gray 8 High Contrast Blue
This is the theme I use the most and 
I thought some of you other minimal theme fans might like it too!
Your system must be patched to allow 3rd party themes
To install copy the Blue HC folder and .theme file to your Windows\Resourses\Themes folder
and then apply it from your Contol Panel\Personalize window
Everything will get themed!
including the Start Page and Login Screens
I use Ribbon Disabler http://winaero.com/comment.php?comment.news.20
but you don't need to as the ribbon will also be themed
You will probably want to disable "Animations in Taskbar as I couldn't remove the flash background(yet)
To do this go to System Properties\Performance Options and uncheck it
Over the next few weeks I will be adding extra's
Like a patched ExplorerFrame to allow for images in the Explorer backgound
The custom imageres.dll I use for the system icons
along with many more custom files
