The Defrag tool in Windows 7 offers some additional options compared to that in Windows Vista. Its command line version has some additional switches.

Defrag /? : gives you all the options.

Here are a couple of useful switches:

/H switch : runs the defragger at a higher than normal priority

/M switch : runs the operation on each volume in parallel

So if you open cmd and type in “defrag /C /H /M” it will run defrag on all volumes, at a higher priority, in parallel.
