Windows 11 cleanup and speed guides, privacy settings walkthroughs, and Kleaner PRO release notes — from the support team.
Every common cause of slow Windows 11 explained: HDD instead of SSD, disk at 100%, startup bloat, updates running in the background, OneDrive, drivers, antivirus and overflowing caches. With a 5-minute diagnosis and a fix order — from free settings to hardware upgrades.
The big Kleaner PRO update: a hang-free cleanup engine, Safe/Recommended/Aggressive/Nuclear presets, dry-run, all browser profiles, the Gutmann shredder, Health Score and the scheduler. Full changelog and why this is the fastest version yet.
A step-by-step Windows 11 cleanup walkthrough: temp, browser caches, Delivery Optimization, WER and Prefetch — what frees gigabytes, what speeds up boot, and what you must never touch. Every system folder explained.
Your SSD's rated speed describes one large file at high queue depth, not the folder copy you are running. Latency, metadata and antivirus explain the gap.
Incognito deletes local traces and nothing more. Five privacy myths — anonymous browsing, deleted history, HTTPS, logout, antivirus — checked against reality.
What Windows 11 sends by default: diagnostic data, the advertising ID, activity history, speech input. The full privacy settings list with exact paths and an honest risk assessment of each.
The Windows 11 right-click menu lags because Explorer builds it on demand from modern components and third-party handlers, not because your PC is old.

In 2003 a cleaner freed real space on a 40 GB drive; by 2025 the basics are automated. An honest history of what PC cleaners did, lost, and still do well.
Machines that stay tidy for years don't belong to weekend marathon cleaners — they belong to people with boring one-minute routines. Seven habits, no deep-cleaning.
A restore point snapshots the registry, system files and drivers — never your documents. What it saves, what it never touches, and when to create one.

Feature updates fail on cramped disks and missing backups. The 20 GB rule, the Windows.old math, the BitLocker key and the backup that saves your evening — one honest checklist.
A corporate laptop is managed territory. Clean your own junk — caches, temp, downloads — and leave services, logs and managed apps alone: the exact line, and why crossing it costs you.
Clear History removes one list. Cookies, site data, autofill, the Windows DNS cache, Jump Lists and the synced copy on other devices survive — here is the honest cleanup.
