Clean Temp Files

Remove Temp Files performs a deep cleanup of temporary data that accumulates across Windows, browsers, applications, and system caches. It targets Windows temp directories, browser caches (Chrome, Firefox, Edge), Windows Update leftovers, crash dumps, thumbnail caches, and application temp data. On average, this repair recovers 2-10 GB of disk space. It only removes files that are safe to delete — it never touches user documents, downloads, or application data. Runs in about 2 minutes with no restart required.
