Questions and Answers

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.

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.

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.

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.

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.

Disk Analyzer helps review large files, possible duplicates, empty folders and program leftovers. Recoverable space varies widely by device and usage; check each path and file before deletion.

The one-time trial provides access to the core tools for 30 minutes. Features marked PRO—such as AutoTune profiles, large-file and duplicate searches, full Smart Care cleanup, selected advanced tweaks, and organization-only KMS client setup—require an activated paid license even during the trial. KMS also requires a valid Windows volume license and your organization's server. No payment card is required.

No. Every paid plan unlocks the same PRO feature set. The 30-day plan lasts 30 days on one PC, the yearly plan lasts 365 days on one PC, Lifetime does not expire on one PC, and Family covers up to five PCs.

The PRO-marked features include one-click AutoTune routines, large-file and duplicate searches, full Smart Care cleanup, selected advanced Windows tweaks, and organization-only KMS client setup. KMS requires a valid Windows volume license and your organization's server; public KMS servers are not used.

The key binds to your hardware fingerprint (CPU, motherboard, disk). You only need to be online during activation — afterwards the app works offline.

Every standard plan binds to exactly 1 PC; Family covers 5. You can move the license to a new computer at any time from the app or the activation portal.

Yes: Windows 7 SP1, 8.1, 10 (1903+) and 11, x64. On Windows 7 a compatibility mode kicks in, and 10/11-only tweaks are marked and hidden automatically.

The Privacy section holds 40+ ready tweaks: telemetry, advertising ID, input tracking, camera and microphone access for apps. The Apply All button enables Ghost Mode — the full baseline in one click.

Write to support within 14 days of purchase and you will receive a full refund — no questions asked.

Press Ctrl+Shift+Del, choose "Cached images and files", set the range to "All time" and clear. Leave "Cookies" unchecked to stay logged in everywhere. Kleaner PRO's Browser Cleaner does this for every installed browser and every Windows profile in one pass.

Stay connected to the internet for 24–48 hours first: re-linking usually resolves itself. If not, open Settings → System → Activation → Troubleshoot. Linking your digital license to a Microsoft account makes the fix a one-click operation. Our activation guide lists every error code and its solution.

Start with Settings → Apps → Installed apps and run the program's uninstaller. Check any leftover AppData folders manually: they may contain settings or projects. Kleaner PRO can help inspect installed apps and common stale registry references, but review every path before deleting it.

Settings → Apps → Installed apps → (app) → Advanced options → Background apps permission → Never. Doing this for a dozen apps is tedious; the Kleaner PRO tweaker switches them in bulk, with honest labels for the few that should stay on.

Search Windows for “Create a restore point”, open System Protection, select the system drive, enable protection if needed, then choose Create. A restore point is not a backup of personal files. Create it yourself before registry edits; Kleaner PRO does not create one automatically for registry repair.

SMART attributes tell the real story: reallocated sectors, wear level, temperature and power-on hours. Kleaner PRO reads them and translates into a plain-language verdict plus live temperature monitoring — a dying drive is better caught weeks early.

Reliable duplicate detection compares content hashes (SHA-256), not file names: same name does not mean same file. Kleaner PRO's Disk Analyzer builds hash-verified duplicate lists with preview before deletion. The amount you can reclaim depends on the folders you scan and the files they contain.

Four levers matter: Game Mode on, background apps off, current GPU drivers, and free RAM/disk headroom. Kleaner PRO's Game Mode applies the OS-level set in one click, and its RAM optimizer frees memory right before you launch the game.

Low free space can interfere with updates and everyday work. Start with Windows Storage settings, review temporary files and inspect large personal files before deleting anything. The amount you can reclaim depends on the PC; see our disk-space guide for more options.

Yes, officially: Settings → Windows Update → Pause updates (up to 5 weeks). A metered-connection setting keeps them from auto-downloading too. Disabling the update service itself is not recommended — it breaks dependencies and store apps.

There is no need to clean the registry routinely to speed up a PC. If you are investigating a specific issue, review each candidate entry and export the affected key or create a Windows restore point first. Kleaner PRO does not currently provide automatic registry backup or one-click rollback; skip entries whose purpose is unclear.

Family covers 5 PCs with a lifetime license; standard plans cover 1 PC. Licenses are hardware-bound but movable: deactivate the old PC in the app's License Center (or the activation portal) and activate on the new one — the seat frees instantly.

Three official free sources: Windows Update (Optional updates → Driver updates), your PC maker's support page (Lenovo, HP, ASUS…), and the NVIDIA, AMD, Intel sites. The Drivers page in Kleaner PRO unites all three: it searches Windows Update for updates and links to official pages — no driver packs, no paid boosters.

No. Update by symptoms: games stuttering — the GPU driver, unstable Wi‑Fi — the adapter driver, a yellow mark in Device Manager — that exact device. Kleaner PRO shows each driver's version, date and status, flagging outdated and problematic ones.
