ghelmer: That's called "munge" (technical terminology there). It is well known that over time, after installs, uninstalls, reinstalls, updates, constant adding to/removing from the registry, and so on, Windows starts to bog down. Has absolutely nothing to do with defragging (which is a FileSystem issue, whereas "munge" is an OperatingSystem issue). The recommendation is to format your OS harddrive once every year to two (some even recommend six months) and do a complete reinstall to boost performance (with all caveats about backing up and saving important configuration information).

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
