Using a PC with powerful specifications does not guarantee that you’ll always enjoy high performance. That’s because Windows’ way of handling software affects every PC’s speed over time.

Whenever you install an application, it scatters traces of itself throughout your system. Many programs also create temporary files they use for a while that ultimately become useless but aren’t deleted. And when you uninstall applications, some leftover fragments continue to weigh your PC down.

Those are the reasons you notice your computer losing its original speed after a few months or years.

If you’re experiencing this issue, it’s not because your hardware is degrading. You just have some house cleaning to do. In addition, you can tweak some system settings and carry out routine maintenance to speed up Windows.

You’ll find steps on how to fix a slow computer in this article.

That said, specialized software programs can help you remedy slow computer performance. We’ll show you the best options to go for.

Auslogics Disk Defrag

Auslogics Disk Defrag is one of the most advanced disk defragmenters

Hard disk drives become considerably slow when they’re fragmented. Hard drives, by default, store files contiguously. That is, they place pieces of files one after the other on the disk.

However, new spaces open up as you delete and write new files. As a result, the drive will scatter file pieces across different sectors because it has to fill up the newly opened spaces. Over time, the computer will have to use many resources to track scattered pieces of files, causing performance lags.

That’s where defragmentation comes in. Auslogics Disk Defrag is one of the most advanced disk defragmenters, as it comes with features not included in Windows’ native defragmentation tools. In addition, it’s known for its speed and UI customization features.

You can use the tool to defrag your hard drive in under 10 minutes. You can also see the files affected by fragmentation with their location on the disk map.

Additionally, you can save time by defragging only the files and folders you want to defragment.
