CCleaner is one of the most trusted apps among Windows power users—with an Android version too. It gained fame during the XP era, when weekly cleanups were essential to keep systems running smoothly. Even today, on modern Windows 10/11 with powerful hardware, maintenance remains crucial.
Windows still accumulates clutter, from bloatware in suites to everyday temporary files. Searching for the best cleaners? CCleaner tops the list, followed closely by Glary Utilities. While Glary offers more than just cleaning, both excel at core maintenance tasks. Let's break it down to help you choose.
Both tools handle essential cleanup: registry fixes, temporary file removal, app caches, browsing history, uninstalls, and startup management.
CCleaner opens to the Cleaner tab by default. Switch between Windows and Apps tabs to select cleanup targets. Windows options include emptying the Recycle Bin, clearing clipboard, log files, memory dumps, and more.

The Apps tab covers browsers, Photoshop, media players, and tools like 7-Zip.

CCleaner smartly targets junk like temp thumbnails and logs, but always review selections for safety.
Unlike CCleaner, Glary lacks a dedicated Cleaner tab and doesn't offer granular app/browser data control.

Instead, its 1-Click Maintenance scans registry, shortcuts, startups, disk errors, and spyware—all in one go for hassle-free upkeep.
Explore the Modules (formerly Advanced Tools) for specialized features: registry cleaning, privacy protection, disk defrag, space analysis, system exploration, driver management, malware removal, and batch uninstalls.

Glary performs reliably across the board—I particularly love the Disk Space analyzer for spotting hidden bloat.
CCleaner's free edition covers all core cleaning. Pro ($24.95/year) and Pro Plus ($39.95/year) add real-time monitoring, auto-updates, defrag, recovery, and hardware inventory.
Glary's free version includes everything mentioned above for personal use. Pro ($28 one-time) brings auto-maintenance, priority support, and commercial licensing. Glary Free rivals CCleaner Pro Plus in scope.
Cleaner needs are evolving—browsers handle their own cache/history, and Recycle Bin is a right-click away.

Yet Glary fills gaps CCleaner misses:
Glary takes the edge for comprehensive optimization. Use CCleaner if you prioritize precise app cleaning; otherwise, Glary's all-in-one power suffices—no need for both.
