Over time, your computer's hard disk can fill up with unused files and applications. Cleaning up the disk can improve performance, including startup time.

For Windows:

Use the built-in Disk Cleanup tool:

1. Press the Windows key + S and type disk cleanup, then press Enter.
2. Select the drive you want to clean up (usually C:\) and click OK.
