SirCleaner Pro Features
Take your system cleaning further with advanced Pro tools:
Delete, Move or Rename files at Boot
Sometimes, Windows locks files and won’t let you touch them. With this feature, you can queue those files for deletion, renaming, or moving at boot time.
Additionally, you’ll see a full list of pending file changes, giving you total control.
Find Large Files
Running out of disk space? This tool scans your drives and pinpoints the largest files. As a result, you’ll quickly understand what’s using up your storage.
Find Duplicate Files
Features a high-speed hashing engine built to find duplicate files fast. Moreover, you can scan any folder or drive without restrictions.
That way, you reclaim space and reduce file clutter effortlessly.
Cleanup Invalid Windows Firewall Rules
Over time, your system collects outdated firewall rules. By removing them, you speed up firewall performance and avoid unnecessary processing.
This feature detects and deletes rules left behind by uninstalled software.
Compact & Reindex the Windows Registry
Unlike basic cleaners, this tool restructures the registry by compressing it for faster performance. No registry keys are touched or deleted. Instead of deleting random entries, it safely reindexes the registry database.
As a result, your system may boot and run significantly faster. Even better, it includes an analyzer to check if optimization is needed.
Clean Other User Profiles
Managing multiple user accounts? This feature cleans every profile in one go—no need to log in separately.
Consequently, it’s perfect for IT admins, servers or shared systems.
Compact Browser Databases
Scans and compresses browser databases like cookies and history storage. This not only saves space, but can also boost browser performance. Especially on older PCs, in short, it keeps your web browsing light and snappy.
Run As System Account
This allows you to run any program under the system account, including computer management, explorer, regedit and more. Giving you more privileges and access to the system without dealing with permissions. This also allows you to see registry keys hidden to all users and only visible to the system account.
Windows PE & External Drive Scanning
Runs inside Windows PE and clean any connected Windows drive. As a result, it’s ideal for advanced diagnostics and offline maintenance.
