Windows 8, 7, 10, and Vista are all built with a disk defragmentation utility, which automatically performs periodic defragmenting. Unless you need to manually force the defragging process, there’s no action to take. If you want to change when or how often the defragmentation process runs, follow these steps:
1. Click the Start or Windows button in the bottom left.
2. Click Control Panel, then System and Security.
3. Under Administrative Tools, click Defragment your Hard Drive.
4. Click Configure Schedule…
5. Select the schedule you want. Pick a date and time that the computer will be on but is not being used.
6. Click OK.
