Your computer’s C drive is like the heart of your system, storing vital data, applications, and the Windows operating system itself. Over time, this drive can get cluttered with unnecessary files, which can slow down your PC’s performance. In this article, we’ll take you through the steps to effectively clean your C drive on both Windows 10 and 11. By following these maintenance tips, you can free up space and optimize your computer for smoother operation.

Step 2: Uninstall Unnecessary Applications

Over time, you might accumulate applications you no longer use. Uninstalling them can free up valuable space on your C drive.

  3. Adjust the disk space usage for system restore points or disable them if necessary.

Step 4: Remove Large and Unneeded Files

Identify and delete large files or folders that you no longer require:

  1. Use Windows File Explorer to search for large files.

Step 5: Empty the Recycle Bin

Don’t forget to empty your Recycle Bin to permanently delete files:
