Windows Update Cleanup

When you install Windows updates, the operating system keeps older versions of system files as backups, allowing you to uninstall updates later and troubleshoot issues. In most cases, deleting these backup files is safe.

Downloaded Program Files

Downloaded Program Files contain ActiveX controls and Java applets that are automatically downloaded from the internet when viewing certain web pages. These files are temporarily stored in the Downloaded Program Files folder on your hard drive and can be safely deleted.

Temporary Internet Files

The Temporary Internet Files folder stores web pages on your hard disk for quick viewing, preserving personalized settings, but clearing this folder will only temporarily free up space as the browser cache will refill automatically, and this only applies to Microsoft browsers.

Delivery Optimization Files

Delivery Optimization files are files that were previously downloaded to your computer and can be deleted if currently unused by the Delivery Optimization service.

Temporary Files

If you check this option, Disk Cleanup will delete temporary files that haven't been modified in over a week.

Recycle Bin

The Recycle Bin holds deleted files until you empty it, after which they are permanently removed.

Thumbnails

Windows stores thumbnails of images and documents in a cache to speed up folder browsing, and these thumbnails are automatically regenerated if deleted.
