Using Disk Defragmenter in Windows

Over time, the files on your hard drive become fragmented and your computer slows down because it has to check multiple locations on the drive. To make your computer run more efficiently, you can use the built-in Windows tool to defragment those files. This article will show you how to use Disk Defragmenter in Windows operating system versions.

Note about solid-state drives (SSDs): SSDs work differently than traditional mechanical hard drives . SSDs do not need to be defragmented, and doing so wears out the drive. However, Windows defragments SSDs once a month if necessary and if the user has System Restore set up. You don't need to worry about this because automatic defragmentation is meant to extend the life and performance of the drive.

So with SSDs, let Windows do its thing and you don’t need to worry about defragmentation. You can use the Optimize Drive tool (aka Disk Defragmenter) to perform drive optimization, including sending TRIM commands to optimize performance. However, it doesn’t perform traditional defragmentation on SSDs. For mechanical drives, you can check and fix its fragmentation status.

Defragmenting is a way to improve performance and make your PC faster, so you should do it regularly. The defragmentation process hasn't changed much in Windows 11 and is almost the same as in Windows 10, so everything should feel very familiar.

Use the defragmentation tool from Windows

1. Click the search icon on the Taskbar.
