A few posts back I fingered Vista Disk Defragmenter for running at inappropriate times (namely, while I was working) and slowing my system to a crawl in the process.
What I neglected to do, as reader Jack Darcy wrote to inform me, was explain just how to turn off Disk Defragmenter, to stop it from running whenever it damn well pleases.
My bad--I shouldn't have assumed everyone knew how to do this. Fortunately, it's extremely easy:
1. Click the Start button.
2. Type Disk Defragmenter and hit Enter.
3. Clear the checkbox marked Run on a schedule (recommended). (Sorry, Vista, you can take your recommendation and... well, this is a family blog, so I can't say.)
4. Click OK and you're done!
As I noted in the post mentioned up top, Disk Defragmenter serves an important purpose: to keep your hard drive running at peak efficiency. So if you do decide to pull the plug, make sure to run the tool manually from time to time, or replace it with a third-party defragger.
