SirCleaner One Of The Fastest Junk File Cleaners Out There.

  • Offers powerful junk removal that’s completely free.

  • Need more control? Pro features are available for users who want deeper optimization.

  • Compared to slower alternatives, it is up to 20x faster than many leading tools. This means you can quickly scan, delete, and move on without any slowdown.

  • Moreover, it offers both standard and cookie exclusion lists. Plus, you get import and export options for easier configuration.

  • All the code is written by me, Shane, a real developer who uses what he builds. Therefore, I focus on solving real problems, not marketing hype.

  • Also supports file paths over 256 characters.

  • Want faster backups and better performance? Then getting rid of clutter is essential.

  • Removes unnecessary junk from 1,900+ applications, offering far more coverage than most tools. Including unique items that others don’t detect, such as Razor Installers (Which can grow well over 20+GB after a while as the old installers don’t get removed every time Razor software updates.) and much more!

  • Moreover, you can choose the installer or portable version, depending on how you prefer to work.

  • If privacy matters, it’s also capable of wiping temp files, browser history, cookies, and more.

Customization Options

You can tailor it to your needs:

  • Save and reuse custom presets

  • Choose any UI color or theme, not just light or dark

  • Run from a USB or external drive

Pro Features

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 for deletion, renaming, or moving at boot time.
Additionally, you’ll see a full list of pending changes, giving you total control.

Find Large Files

Running out of disk space? This tool scans your drives and pinpoints the largest. 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 duplicates fast. Moreover, you can scan any folder or drive without restrictions.
That way, you reclaim space and reduce clutter effortlessly.

Remove Invalid Firewall Rules

Over time, firewall rules become outdated. 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 Reg

Unlike reg scanners, this tool restructures the registry by compressing it for faster performance. No keys are touched or deleted. Instead of deleting random entries, it safely reindexes the registry database.
As a result, your computer 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 computers.

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.

Win PE & External Drive Scanning

Runs inside Win PE and work with any connected Windows drive. As a result, it’s ideal for advanced diagnostics and offline maintenance.
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 reg keys hidden to all users and only visible to the system account.
