Main Features Compared
System Cleaning and Disk Cleanup Tools
Ashampoo's Drive Cleaner supports custom filters, and its Internet Cleaner handles Chrome, Firefox, Edge, and Opera. Glary's Disk Cleanup targets temp files, obsolete installers, logs, and internet history.
Registry Cleaning
Ashampoo's Registry Optimizer 2 is far faster than earlier versions, with a Super-Safe Mode and automatic backups. Glary's Registry Cleaner backs up first too; both let you review flagged items before applying changes.
Security and Privacy Tools
Ashampoo includes a Privacy Traces Cleaner, a Privacy Manager with Windows tweaks, a file wiper, and a firewall manager. Glary counters with Tracks Eraser, File Shredder, and a Context Menu Manager; Ashampoo goes deeper into Windows settings.
One-Click Maintenance and Performance Optimization
Ashampoo's One Click Optimizer runs the Internet, Drive, and Registry cleaners in sequence. Glary's 1-Click Maintenance scans registry, shortcuts, disk, tracks, temp files, and startup in one pass.
File Management and Extra Utilities
Ashampoo adds a file wiper, splitter, and encryptor, an undeleter, a duplicate finder, an uninstall manager, and backup tools. Glary offers file recovery, duplicate and empty-folder finders, a disk space analyzer, and a software updater. Ashampoo's built-in uninstaller is basic.
Pricing: Which Offers Better Value?
Ashampoo WinOptimizer Pricing
Ashampoo lists the 2026 edition at $30 on Ashampoo's official WinOptimizer page. Promotions are frequent, so the real price often dips below list, and a 30-day trial plus money-back guarantee covers the risk.
Glary Utilities Pricing (Free vs Pro)
The free edition is the real product, and the Glary Utilities official site makes the download easy. Pro runs about $39.99 per year for up to 3 PCs, though Glarysoft publishes no official price and resellers undercut it.
Real-World Performance Testing
We ran both one-click passes on modern Windows machines. Ashampoo's One Click Optimizer applied the whole cleanup sequence instantly and without errors. Glary's 1-Click Maintenance found 267 registry issues, 86 broken shortcuts, and 1.78 GB of temporary files in under a minute.
The honest caveat: gains are modest. In timed boot testing after a full tuning pass, startup improved from 2 minutes 32 seconds to 1 minute 39 seconds, while benchmark scores stayed flat or dipped. Ashampoo's Overview glance can also under-report junk, showing 1 GB where the Clean tab found 1.8 GB.
Glary's duplicate finder missed most of the duplicates on our test PC, a reminder that the free suite's quality is uneven.
Ease of Use and Interface
Ashampoo WinOptimizer looks modern and reads clearly, with light and dark themes and a start-page dashboard. The All Modules view can overwhelm beginners. Glary Utilities looks dated, like a Windows 7-era app, but every utility stays visible on screen. For newcomers, Ashampoo's interface is the more user-friendly of the two.
