fsutil
This is a handy command. You can do everything from managing your hardlinks to querying the free space in a volume. Type "fsutil" into your command prompt, and you'll see a list of options. I choose "fsinfo" from the list, so I type "fsutil fsinfo" into the prompt. Now I get even more options, but I choose drives by typing "fsutil fsinfo drives." It's fun, it's easy, and you'll get the hang of it. Explore this utility. There are a lot of cool features and hidden twists.

taskkill
Now that you know what's going on behind the scenes, maybe you want to shut a few of these extraneous tasks down. That's where taskkill comes in. Type "taskkill /?" for a quick lesson in the syntax of the command, then shut down all those random processes. I just killed my MS messenger by typing "taskkill /PID 1680." I got the PID from running tasklist, above.
