How to Run Disk Cleanup on Windows 10: A Step-by-Step Guide

posted on June 12, 2025

Running a disk cleanup on Windows 10 is like giving your computer a fresh start. It’s all about deleting unnecessary files that pile up and slow things down. To do this, you can use the Disk Cleanup tool, which is built right into Windows 10. It’s as easy as searching for the tool, selecting the drive you wish to clean, and then letting the software do its magic by removing temporary files, system files, and any other clutter.

How to Run Disk Cleanup on Windows 10

Running Disk Cleanup on Windows 10 helps free up space and improves your computer’s performance by removing unnecessary files. Let’s walk through the steps to achieve this.

Step 1: Open Disk Cleanup Tool

Begin by typing "Disk Cleanup" in the Windows search bar and selecting the program from the results.

The Disk Cleanup tool is a handy utility that’s already part of Windows. By typing its name in the search bar, you quickly find and access the feature without any hassle.

Step 2: Select the Drive

Choose the drive you want to clean up, typically the C: drive, and click "OK."

The C: drive is usually where your system files and most of your programs are stored, making it the primary target for disk cleanup. Selecting it ensures you’re tidying up the most crucial parts of your storage.

Step 3: Choose Files to Delete

In the Disk Cleanup dialog, check the boxes next to the file types you want to delete, like temporary files or system error memory dump files.

This step is where you can customize your cleanup. You decide which types of files are unnecessary, allowing you to keep anything you might want to hold onto.

Step 4: Confirm and Delete

Click "OK" and then choose "Delete Files" in the confirmation box to start the cleanup.

Once you confirm, Disk Cleanup will work on removing the files you’ve selected. It’s like hitting the delete button on clutter that’s been slowing down your system.

Step 5: Clean Up System Files (Optional)

For a deeper clean, click on "Clean up system files" and repeat the process.

This option is for those who want to dig deeper into their system’s storage. It allows you to delete even more files, like old system restore points, that might be hogging space.

After you run Disk Cleanup, your computer should have more free space and might even run a bit faster. By getting rid of unnecessary files, you lighten the load on your system, which can improve performance. You’ll notice the extra breathing room the next time you check your storage space.

  • Use the "Clean up system files" option for a more thorough cleanup.
