Everything your PC needs.
One application instead of a dozen utilities — with real results.
Registry review
Checks common startup, uninstall, shared-DLL and file-handler references. Review every finding and create a Windows restore point or backup before applying changes.
Privacy Shield
40+ one-click tweaks: telemetry off, tracking blocked, camera and microphone control. Ghost Mode applies everything at once.
File Shredder
Offers overwrite-based deletion options. Results depend on the storage device and filesystem; no software method guarantees unrecoverability on every SSD or for synced and backed-up copies.
RAM Optimizer
Working-set trimming and standby-list purge with the right privileges. You see the memory actually freed.
Disk Health & Analysis
Large-file finder, SHA-256 duplicates, S.M.A.R.T. monitoring, plus Space Explorer: top folders, file types and oldest large files with drill-down.
Network Toolkit
Ping with stats, traceroute, port scanner, benchmark of 7 public DNS servers and one-click DNS switching. Plus Winsock reset, connection monitor, WiFi passwords and speed test.
Tweaker & Defrag
76 system tweaks with honest danger levels, volume-map defragmentation, TRIM for SSDs and an unlocker that deletes what Windows won't let you.
Windows Toolbox
Software updates via winget, event log doctor with fix hints, free-space wiper, game mode, services manager, hosts editor, God Mode and more.
Driver Updates
Checks and installs driver updates via Windows Update, lists every driver with version and date, links to official NVIDIA, AMD, Intel pages and your PC maker's support.
Startup App Audit
Search startup entries by name, path or publisher metadata; filter enabled items and signatures that need review, inspect file details, and export the current audit to CSV. Nothing is disabled automatically, and a signature result is not a malware verdict.
Battery & Boot Diagnostics
Review current charge, firmware-reported design and full-charge capacity, cycle count, and boot timing; export the available battery snapshot to CSV. Capacity data depends on what the device reports.
Smart Care: guided maintenance.

How to speed up Windows in 4 steps
Fifteen minutes on this plan — and your PC responds noticeably faster.
- 1
Download and install Kleaner PRO
One installer for Windows 7, 10 and 11 (x64). Installation takes under a minute, the trial starts immediately — no sign-up, no card.
- 2
Run Smart Care
Smart Care scans cleanup categories, then asks separately before registry repair, privacy changes and RAM optimization. Review each prompt; create a restore point before registry changes.
- 3
Review your startup
Startup Manager shows what slows down Windows boot, with the measured impact of each program on startup time. Disable the extras with one click.
- 4
Turn on the schedule
The Scheduler repeats cleaning and RAM optimization on its own — weekly or daily. Keeping speed is easier than winning it back.
Windows cleaner software: compare Kleaner PRO and five alternatives
There is no single best PC cleaner for every Windows user. Some people want an open-source privacy tool; others prefer a one-click maintenance suite or a focused disk cleaner. This guide compares five established alternatives with Kleaner PRO using each vendor’s published feature documentation—not a paid placement, lab test, or claim that one product is universally superior.
Kleaner PRO — the Windows optimizer that explains every action
A Windows junk and cache cleaning program with 130+ tools: from temp files to deep privacy control.
What Windows cleaning in Kleaner PRO actually does
Windows and apps create temporary files, browser caches, crash reports, thumbnails and update leftovers. The amount varies substantially by device and usage. Kleaner PRO lists detected categories, paths and sizes so you can review proposed cleanup before applying it; check each item and keep a backup of important data.
When clearing cache helps—and when it doesn't
Browsers and Windows keep cached data so repeat tasks can load faster. Clearing it may reclaim storage or help troubleshoot corrupted cache data, but apps may rebuild or download files again, making the first load slower. Cache cleanup does not make a drive physically faster or fix unrelated performance problems. Kleaner PRO includes a browser-cleaning tool for cache, cookies and history; removing cookies can sign you out of websites.
Is registry cleaning safe?
The Windows registry stores system and application settings. Kleaner PRO checks six common areas for references to missing startup files, uninstall records, shared DLLs, file handlers, MUI cache entries and TypeLib paths. A missing path is not always safe to delete, so treat scan results as candidates and inspect them individually. The app does not create a registry backup or restore point automatically; use Windows System Protection or export affected keys before making changes.
Privacy and telemetry
Windows 10 and 11 collect diagnostics, an advertising identifier, typing history and app-usage data by default. The Privacy section contains 40+ verified tweaks: telemetry off, tracking blocked, camera and microphone access controlled, UWP background activity restricted. Every tweak carries an honest description of the risks — and Ghost Mode enables the whole baseline with a single click.
KMS activation: the corporate mechanism and the fakes
KMS (Key Management Service) is Microsoft's volume-activation mechanism for organizations: a company runs a KMS host on its own network, and its Windows and Office installations activate against it, renewing every 180 days. Kleaner PRO includes an organization-only KMS client setup console for licensed Windows 10/11 volume activation — it needs a valid Windows volume license, your organization's KMS server and a paid PRO plan. Public “KMS activators” that promise free activation forever are piracy tools and one of the most common malware delivery routes; the activation they fake breaks at the first recheck, and the installer often smuggles trojans.

Frequently asked questions
How do I clean the Windows cache on Windows 10 and 11?
Launch Kleaner PRO, open System Cleaning and press Scan. Review the reported system and browser caches, update leftovers and temporary files before choosing what to remove. Windows Storage settings and Disk Cleanup are also useful built-in options; the available categories differ.
Why is my computer slow — and will Kleaner PRO help?
Slowness can come from low free space, startup apps, background work, overheating, a failing drive or Windows errors. Check Task Manager and free disk space first. Kleaner PRO can help review temporary files, startup entries and system information, but cleaning alone cannot diagnose every cause or guarantee a speed increase.
Is it safe for my files?
Review the selected cleanup categories and file list before confirming. Some actions are permanent, and browser cookies can sign you out. Keep a separate backup of important data; do not assume a cleaner can restore deleted files.
How is Kleaner PRO different from CCleaner?
They are independent products from different developers. Kleaner PRO describes a Windows toolkit for cleanup, privacy settings, disk analysis and system utilities. CCleaner offers its own Health Check, cleaning and startup workflows; some features depend on plan. Compare current features and terms on the vendors’ official sites.
How do I clean the Windows registry safely?
Kleaner PRO checks common stale references in six registry areas, including startup entries, uninstall records, shared DLLs, file handlers, MUI cache and TypeLib paths. Results can be false positives: inspect them carefully. The app does not automatically create a restore point or registry backup, so create one in Windows before applying changes.
