What's new in Kleaner PRO

Every change in plain words. The latest version is on top.

v11.0.1.20

Current2026-09-27
  • Fixedv11.0.1.20: trial time is persisted across app restarts and version upgrades; losing local markers no longer grants an offline trial, and a server reset is accepted only from the authenticated admin tool.

v11.0.1

2026-09-27
  • NewOS auto-detection in the Tweaker — tweaks that need a different Windows version (Appx and Defender policies on Windows 7, the classic menu that only exists on Windows 11, and so on) are shown grayed out with a badge, and the backend refuses to apply them too — nothing silently "succeeds" without effect
  • FixedSwitching OFF five command tweaks (hibernation, NTFS last-access timestamps, 8.3 short names, TCP autotuning, SMB1) silently did nothing — the revert command sat in the wrong slot and never ran; rollback now actually executes powercfg, fsutil and netsh restores
  • FixedThe scan crash (0xC0000005 seconds after pressing Scan on Windows 10 21H2+) is fixed — the TEMP folder lookup called GetTempPath2W with swapped arguments, so Windows received the number 260 as a pointer
  • FixedThe "updateTrialBanner is not defined" UI error is gone — it silently killed the bottom half of the interface script, hiding the trial progress bar and the Premium card
  • FixedThe updater no longer offers to update to the already installed version — the interface version now comes from the binary itself
  • ImprovedHonest "no auto-revert" labels on one-way actions (Edge uninstall, OneDrive uninstall, Microsoft Store apps) with an explanation of how to bring them back — before you switch them off, not after
  • ImprovedTelemetry scheduled tasks now have a real revert — switching the tweak off re-enables all six tasks instead of only clearing an internal marker
  • ImprovedThe hardware fingerprint is pinned to the last fully successful reading — the trial and license identity no longer flip between two values on the same machine

v10.9

2026-09-20
  • NewInstant scan results with IndexedDB — the previous scan is cached locally, so the Cleaner page shows results immediately on launch instead of an empty page
  • NewFound-files list with instant search — up to 500 junk file paths (temp + logs) are indexed in the UI and filtered as you type without rescanning; browser cache is now broken down per browser
  • NewTotal-cleaned statistics — every cleanup is recorded locally (IndexedDB), the Dashboard shows all-time bytes freed and the cleanup count, resettable from the card
  • ImprovedWebsite purchase resume — the store remembers your unfinished order locally and offers a one-click return to payment if the payment tab was closed
  • ImprovedActivation portal remembers recently checked keys (stored only in the browser, IndexedDB) for one-click re-checks

v10.8

2026-09-19
  • ImprovedSupport contacts are now everywhere — clickable email and Telegram on the activation screen, in Settings and on the license page, plus the website footer and purchase emails
  • ImprovedVersion number removed from the app sidebar and the Settings about card — the header now shows only the logo and the name; the update check still compares versions and offers upgrades
  • ImprovedLicense agreement moved from the sidebar header into Settings (Support section) — the first-run consent dialog is unchanged
  • FixedWebsite .env shipped placeholder support contacts that overrode the real ones in code — fixed to the real email and Telegram handle
  • ImprovedInstaller delivery chain verified — the build script writes manifest.json next to Kleaner-Setup.exe, and the site picks the new version up within a minute without a container rebuild

v10.7

2026-09-19
  • NewDriver Updater page — real search and install of driver updates from the official Windows Update repository (Microsoft WUA API), live download and install progress, honest reboot notice
  • NewFull driver list with versions, dates and digital-signature status — problem devices (yellow Device Manager marks) and 4+ year old drivers are flagged, each row links to the official vendor site (NVIDIA, AMD, Intel, Realtek...) with free auto-detect tools
  • NewPC maker support card — detects your computer manufacturer (ASUS, Lenovo, HP, Dell, MSI, Acer...) and links to its driver page for your exact model
  • FixedActivation window no longer flickers every 2-4 seconds — while the trial is expired the key input is no longer wiped and re-created on every background poll; typed keys and focus are preserved
  • FixedApp icon is now crisp in the title bar and taskbar at any DPI — both large and small icon sizes are set explicitly (was: a single scaled-down size)
  • ImprovedProminent sidebar logo — full-colour gradient badge with the K shield plus bold Kleaner PRO text (was: a thin 20px outline icon)
  • ImprovedBackground CPU, RAM and disk polling pauses while the activation window is open — less WMI traffic and no licenseRequired spam
  • ImprovedSite SEO — new knowledge-base article on updating drivers for free in 7 languages, Driver Updater in the feature list and FAQ, fresh landing content

v10.6

2026-09-19
  • NewNetwork Doctor on the Network page — one click clears the DNS cache and resets Windows network settings with a step-by-step checklist and a restart hint (fixes most cases when the internet stops working)
  • NewMicrosoft telemetry blocker on the Privacy page — adds 23 telemetry server addresses to the hosts file, shows how to undo
  • NewBuilt-in Windows bloatware remover on the Uninstaller page — 19 pre-installed apps (Cortana, Xbox, Clipchamp...) removed in one click, list shown before removal
  • NewFile Unblock button on the Unlocker page — removes the downloaded-from-the-internet mark (Mark of the Web) and the read-only attribute
  • NewEnvironment variables editor (Windows Tools) and tweak-history clearing (Settings) — both backends existed but were unreachable from the interface
  • FixedSmart Care is now event-driven — each step waits for the real backend response instead of a fixed timer; results and counters can no longer show zeros on slow disks, the watchdog stops the run honestly if a step hangs
  • ImprovedHealth diagnostics on the Dashboard are translated into all 7 interface languages (raw English strings such as Critical: under 5 percent free space no longer leak into the localized UI)
  • ImprovedNetwork reset and telemetry blocking moved off the UI thread — the window cannot freeze while netsh and hosts write is in progress

v10.5.2

2026-09-18
  • FixedTweaker and Defrag pages no longer flicker or stay empty — bridge responses now update the page in place and data requests are sent exactly once (was: an infinite re-render loop)

v10.5.1

2026-09-18
  • ImprovedFull system benchmark — multi-core CPU, RAM bandwidth, disk sequential + random 4K with live progress (20-40 s real measurement)
  • FixedTabs can no longer fail to open — a page error now shows a readable card instead of a dead tab, and is logged to app.log
  • FixedSSD detection without admin rights (correct TRIM button on the Defrag page)

v10.5

2026-09-18
  • NewPower Pack: Space Explorer — top folders, file types, largest and oldest files with drill-down
  • NewSoftware Updater — outdated app detection and silent one-click installs via winget
  • NewNetwork Toolkit — ping, traceroute, port scanner, DNS benchmark and one-click DNS switch
  • NewEvent Log Doctor — 14 days of errors and crashes with fix hints
  • NewWipe free disk space, process RAM trim, startup signature guard, monitor alerts
  • ImprovedRebrand: the product is now Kleaner PRO (kleaner.pro) — new name, logo, icons and the KP-XXXX license key format

v10.4.3

2026-09-18
  • ImprovedRedesigned loading states (centered spinners, skeleton table rows), unified soft shadows, defrag percent moved into the header row

v10.4

2026-09-18
  • FixedLicense activation now works reliably — RSA signature verification was rejecting every valid key
  • FixedStartup list and disk list are visible again — two broken JSON responses made both pages blank
  • FixedRAM and disk stats on the dashboard show real numbers instead of zeros
  • FixedBackup restore no longer truncates settings and tweak history
  • FixedClicking a disk card in Disk Analyzer and a volume in Defrag works with real Windows paths
  • FixedWebhooks: paid orders can no longer be lost on a temporary database hiccup — the gateway retries until the key is issued
  • FixedCrypto checkout page keeps polling as long as the payment window is open
  • SecurityAdmin token rotation, rate limits on all admin endpoints, unspoofable client IP handling
  • SecurityCommand-injection fixes in defrag, uninstall and power-plan paths
  • NewSystem Report — one-file HTML snapshot of your PC (hardware, disks, top processes, startup)
  • NewWindows services manager, network adapter inspector and KMS console in Windows Tools
  • ImprovedForce-delete and other long operations moved to background threads — the UI stays responsive
  • ImprovedModern rounded design — soft shadows, glass surfaces, smooth micro-interactions
  • ImprovedWebsite SEO overhaul — hybrid titles, FAQ page, HowTo, comparison table, structured data in 7 languages

v10.3

2026-09-17
  • NewInterface scale setting (90 to 150 percent) with Ctrl +/- shortcuts
  • FixedHiDPI: window and fonts render at proper logical size on 125-150 percent screens
  • FixedRegistry scan results no longer re-render the whole Settings page
  • Improved20 browsers detected by the browser cleaner, including Opera GX and beta channels

v10.1
