We keep installing, uninstalling the software and also deleting the files from our PC. Over a time files on hard disk drive get fragmented and the PC slows down because it has to check multiple places on your hard drive for those pieces. To overcome this issue, Windows PC comes with a built-in Defragmentation tool.

Like Windows 8 and Windows 7, the Windows 10 also automatically defragments files for you on a schedule (by default, once a week). However, it doesn’t always run consistently, so if you notice that files are taking longer to load, you can do the defragmentation manually in Windows.

How to Defragment Hard Disk Drive in Windows 10?

When Defragmentation done, your drive should say 0% fragmented in the Optimize Drives. If it is more than 0%, you have to re-optimize.

Here you can also change the Schedule of Defragment, by clicking on “Change Settings” under Optimize Drives. You can schedule Daily, Weekly or Monthly.
