MS Windows is an abominable product line, and Vista is especially horrible. Ugh!
Okay, sure. It accomplished a lot of nifty things. The problem is that the Microsoft designers, thinking like a bunch of high school students, decided to focus on superficial 'gee whiz' features to the deteriment of functionality.
When you boot up the computer, it should NOT attempt to do too many things in the background. When you call up Windows Explorer, it should come up fairly quickly, without a lot of pre-processing; after all, it's primary function is to let the user navigate through the directory structure, and that shouldn't take much effort at all. Instead though, calling this program up can be a slow and tedious process, all because Microsoft insists on doing so much stuff in the background. (What exactly? I don't know, but I'm sure that generating thumbnail images and/or picture indices is one of them. Who cares about that?!?!? You don't do that sort of thing unless you KNOW that the user will be navigating to the folders in question.)
Great googly moogly.
