In your “Better, Faster, Stronger” article (July 2009), one of the tricks you recommend is to defrag my computer. I have Vista and I am trying to do a full defrag through the command line. It will not allow it without an “administrator command prompt.” What is an administrator command prompt? I am the only user and my account is an administrator account. Any advice?

Jed, for security reasons, Vista’s User Account Control won’t run programs with administrator permissions by default, even if you’re the only user. To run an administrator command prompt, use the search bar in the Start menu and search for cmd.exe. When it shows up, right-click it and select “Run as administrator.” Alternately, you can just search for cmd.exe and hit Ctrl-Shift-Enter to open an administrator command prompt.
