Windows has molasses in its code

After using MS Windows here at work and at home I have noticed a bizare "feature" of Windows. Windows takes a long time to do some very basic things. As an example, I wanted to delete a small JPEG file from the desktop. The file was only about 40K in size. So to do this on Windows, you select the file and press the delete key. Of course Windows asks you "Are you really sure you want to delete this file?". Why this matters is beyond me because all it does it put it in the recycling bin. It does not get anialated. But to do this a window pops up showing a picture of a file flying through the air until it vanishes. And does this repeatedly until the file is deleted. Which actually takes about 5 seconds! Not 1/2sec like you would expect for it to update the directory and say the file is now in the recycle bin. On the Mac there is no question of your competence to delete files which go to the Trash. And there is a quick instant feedback of something like "KerPlunk" and the file is gone. About 1/4sec tops. I know this is minor but just another Window's quirk. I have noticed the same long delay for setting a preference on the Taskbar (Window's Dock). I check off the "hide Taskbar" option and it again churns for a while before completing. What gives?
