Does your PC react slow, freezes, or takes forever to load apps? Well, the chances are your system is messed up with unnecessary files, duplicate data, and background processes.

The good news? You don’t need a new computer system.

With the right cleanup strategy, you can boost speed, free up disk storage on the computer, and improve performance.

Quick Answer: How Do You Clean Up a Computer to Make It Run Faster?

In order to clean up your computer and make it run faster, you can remove temporary files, clear your C drive with Storage Sense, delete duplicate files, uninstall unused programs, disable unnecessary startup apps, and clear your browser cache. Doing all 6 can free up several GB of space and speed up boot and load times. Below is the full step by step process.

Why Is My Computer Running Slow?

It is common that over time, your computer collects junk. Here is what is usually piling up in the background.

  • Temporary files: Apps and Windows generate temporary files constantly. And most never get automatically cleared. On a machine that is a year or two old, this alone can easily add up to several gigabytes.
  • Duplicate files: The same image saved 3 times from WhatsApp or other platform, and a document file you downloaded twice. These do not only waste storage space; they also slow down search and indexing.
  • Startup programs: Every application that adds itself to your startup list is fighting for CPU and RAM the moment you turn your PC on. 10 background apps loading at boot can add 30+ seconds to your startup time alone.
  • Browser cache and logs: These generally grow silently in the background and rarely get touched unless you clear them manually.
  • Unused installed apps: There may be software that you installed once and forgot about. They are still there on your device using disk space and sometimes running background services.
