OK I found this to be interesting… Apparently there is a bug in Windows 7 that causes a 30 second startup delay when you opt to use a solid color background vs. a background image of any kind…

Now, I’ve never developed (or been a part of developing) an entire operating system, so I guess my point on this may be way off base, but does this bug make any sense at all? To me, from a programming perspective, no… not at all!

Supposedly there is a patch/workaround for it, though I haven’t tried any of it (I have Windows 7 at work, I may be tempted to test it out tomorrow just for the sake of verifying it first hand).
You can find info about the patch and workaround here: Lifehacker article.
