Let’s break it down step by step.

Step-by-Step Tutorial to Clean C Drive in Windows 11

In this section, we’ll walk through the essential steps to clean your C drive in Windows 11. By following these steps, you’ll be able to free up space and improve your computer’s performance.

Step 1: Open Disk Cleanup

Search for "Disk Cleanup" in the Start menu and select the app.

Disk Cleanup is your go-to tool for getting rid of temporary files and system junk. It’s built into Windows, so you don’t need to download anything extra. Just type "Disk Cleanup" in the search bar next to the Start menu and click the app when it appears.

Step 2: Choose C Drive

When prompted, select the C drive from the dropdown menu.

After opening Disk Cleanup, you’ll need to select which drive you want to clean. For the purpose of this tutorial, choose the C drive, where your operating system is typically installed. This will allow the tool to scan for unnecessary files taking up space.

Step 3: Select Files to Delete

Check the boxes next to the file types you want to remove.

Once the scan is complete, Disk Cleanup will present a list of file types you can safely delete, such as Temporary files, Recycle Bin contents, and Thumbnails. Check the boxes next to the ones you want to get rid of. If you’re unsure, hover over each option for a description.

Step 4: Confirm and Delete

Click "OK" to remove the selected files and then confirm.

After selecting the files you want to delete, click the "OK" button. Disk Cleanup will ask you to confirm that you wish to permanently delete these files. Confirm your choice, and the tool will start clearing out the clutter.

Step 5: Uninstall Unnecessary Programs

Open the Settings app, navigate to Apps, and uninstall programs you no longer use.

Old and unused programs can take up a lot of space. Open the Settings app, go to the Apps section, and scroll through the list. If you see something you don’t use anymore, click on it and select "Uninstall."

Step 6: Check for Large Files

Use File Explorer to find and move or delete large files.

Open File Explorer and navigate to the C drive. Use the search bar to look for files by size. You can then decide whether to move them to an external drive or delete them if they’re no longer needed.

Once you’ve completed these steps, you should notice more available space on your C drive. Your computer might also feel snappier and more responsive.
