About this tag
Disk cleanup on Windows involves using built-in tools like Disk Cleanup, Storage Sense, and Cleanup Recommendations to safely reclaim storage space by removing temporary files, update leftovers, caches, and other non-essential data. The classic Disk Cleanup utility includes a 'Clean up system files' button that reveals additional removable items such as Windows Update Cleanup files. Storage Sense automates cleanup tasks in Windows 10 and Windows 11. Third-party tools like BleachBit offer preview-based selective cleaning. Advanced users may use DISM commands or AI-guided analysis to identify hidden space hogs, but caution is advised to avoid disrupting system reliability. Best practices emphasize understanding what is deleted and prioritizing built-in tools over aggressive third-party cleaners.

    A viral X post says Windows keeps a thumbnail of every photo you've ever deleted. Part of that is true. Windows 11 can keep a small preview of a picture after the picture itself is gone.
