By default Windows Vista will automatically defrag your hard drive (defrag: reorder files on the physical hard disk and not to make them easily accessible / re-organising your file cabinets).
The default is that Vista itself schedules the best time for this to do, while this could decrease real-time performance it might be better if you choose when to defrag yourself. An easy way to disable this scheduled defragmentation is as follows.
- Click START, type dfrgui and hit ENTER.
- Then uncheck Run on a schedule (see figure 1) and click OK.
Note: While the above is a lot faster 🙂 you can also do this by browsing to Control Panel, System and Maintenance, choose Defragment your harddrive.
