One application instead of a dozen utilities — with real results.

Deep Cleaning

Temp files, browser caches, update leftovers, thumbnails, prefetch and logs — scanned and cleaned in seconds.

Registry review

Privacy Shield

40+ one-click tweaks: telemetry off, tracking blocked, camera and microphone control. Ghost Mode applies everything at once.

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.

How to speed up Windows in 4 steps

Fifteen minutes on this plan — and your PC responds noticeably faster.

  1. 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. 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. 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. 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.

Why cleaning the cache speeds up your computer

Browser and system caches exist to make things faster — but an overflowing cache does the opposite: your antivirus takes longer to scan it, the disk has nothing left to read sequentially, and updates fail to write over stale data. Cleaning the Windows and browser caches returns the disk its speed and gives your browser fresh data. Kleaner PRO has a dedicated browser-cleaning mode that clears cache, cookies and history across every installed browser at once — including multi-user profiles.

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.

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.
