Defragmentation will rearrange the fragmented files, organizing them into sequential blocks, and increase the performance of your computer.

Defragmenting your system drive is a straightforward process that can be carried out by anyone. There are several ways to defragment your system drive, including using the built-in Windows disk defragmenter or third-party software. In this article, we will provide you with a step-by-step guide on how to defragment your system drive using the Windows disk defragmenter, ensuring that your computer runs smoothly and efficiently. So, let us dive into the process of defragmenting and optimizing your system drive.
