Editor's Summary · Disk Cleanup Software
Try an analyzer before a cleaner. On most machines the missing space is a handful of large forgotten files — old disk images, downloads, virtual machines — not accumulated junk, and WinDirStat, TreeSize, DaisyDisk, GrandPerspective and SpaceSniffer will show you that in under a minute. Several of them are free.
If you want automated cleaning, CCleaner, BleachBit and Wise Disk Cleaner do it without much ceremony. BleachBit is open source, which is worth something in a tool whose whole job is deleting your data.
The optimization suites — Advanced SystemCare, System Mechanic, Glary Utilities, BoostSpeed — bundle cleanup with registry repair and performance tuning. The cleanup part works. Treat percentage speed-up claims as marketing, and note that registry cleaning has little measurable benefit on modern Windows.
For uninstalling, Revo and IObit Uninstaller remove the leftovers that vendors' own uninstallers do not.

How to choose Disk Cleanup Software
Run a free analyzer first. It costs nothing and usually finds the problem outright, which tells you whether you need to buy anything at all. If you do want automated cleaning, prefer a tool that shows what it will remove before it removes it, and be cautious with registry cleaners — the upside on modern Windows is small and the downside is a broken application. On SSDs, ignore defragmentation entirely.
