Windows XP contains lots of tools that the regular user might never use, built in performance monitor is one of them! It's constantly examining a few areas of your system. This information can be called up using the performance monitor application found in the administrative tools.

Most of us can care less of this sort of performance statistics monitoring tool, we usually leave that type of task to our System Administrator (FixPCNetwork).

The problem is, XP is always monitoring by default, and some of its observation tools can use a considerable amount of processing power. So it is a good idea to turn this monitors off if you are not planning to use them.

It is very easy to do this: Go to the command prompt ( Start -> Run then type 'cmd' click Ok) and type 'diskperf -N' that's it you are done!
