 Use Built-in Disk Cleanup Tool

3. Select Files to Delete:
• Check the boxes next to the file types you want to delete (e.g., Temporary files, Recycle Bin, System created Windows Error Reporting, etc.).
• Click OK, then confirm by clicking Delete Files.
  
  
  
4. (Optional): Clean Up System Files:
• In the Disk Cleanup window, click Clean up system files.

Use Storage Sense (Windows 10/11)

2. Turn on Storage Sense, or click Configure Storage Sense or run it now.
3. You can set it to run automatically or run it manually by clicking Clean now.

Tips:

• Use system file cleanup after major updates to recover several GB of disk space.
• If you're comfortable with command-line tools, run cleanmgr.exe or cleanmgr /sageset:1 for advanced options.
