Standard Windows blue like they’ve had since 3.14 I only see it when the computer boots so I don’t really bother with anything.
Gald to see I’m not the only one 
Actually so that I see less of my desktop I have all the application icons I use most often - Excel, Word, Notepad, TOAD, email client, calculator, IE and others, on my start button. So once I have started my first application for the day I usually don’t see it again until I shut down evrything I’m using.
