A nice feature to have for computer illiterate people, but if I'm trying to squeeze every bit of power and disk bandwidth out of this machine, I'm going to stop this disk heavy process from starting on its own.
Get to the options by:
- Clicking on the Start Menu
- All Programs
- System Tools
- Disk Defragmenter (Alternatively you can just run "dfrgui.exe")
- Click the "Configure Schedule" button
- Untick "Run on a schedule (recommended)"
