🧹
Junk & cache cleanup, preview first
Windows temporary files, the Windows Update download cache, thumbnails, crash dumps, the Recycle Bin and browser caches. You see the real size and file count of each one, tick what goes, and nothing is deleted until you confirm.
⚡
Startup manager
Every program that starts with Windows, with the impact Windows itself measured at your last sign-ins. Turn one off the same way Task Manager does, and turn it back on with one click. Services are shown read-only, so nothing important gets switched off by accident.
📁
Large files & duplicate file finder
A size-sorted view of your folders and the biggest files in them. Duplicates are found by content (SHA-256), never by name, and at least one copy of every group always stays. Files you remove go to the Recycle Bin, and Undo puts them back.
🔒
Privacy cleaner
Browsing history and cache in Chrome, Edge, Firefox, Brave, Vivaldi and Opera. Cookies and saved passwords stay unticked unless you tick them yourself, because clearing them signs you out of websites.
💾
Drive health & optimize
What your drives report about themselves: SMART failure prediction, temperature, wear and errors. Optimizing runs Windows’ own optimizer: TRIM for SSDs, defragmentation only for hard disks. An SSD is never defragmented.
🛡
Security at a glance
Microsoft Defender status, a Defender quick scan, the firewall and Windows Update, on one screen. We don’t sell our own antivirus: Defender is built into Windows, and if you use another antivirus, the app shows that too.
📅
Weekly maintenance, if you want it
Once a week it cleans the safe categories only (temporary files, update cache, thumbnails, crash dumps, closed browsers’ caches) and shows a short summary. It never touches the Recycle Bin, passwords, cookies or your files.
↩
Restore point, action log and Undo
A Windows System Restore point is created before every batch of changes. Every change is listed, and anything Windows can undo (startup changes, files sent to the Recycle Bin) has an Undo button.
