SwiftClean is a lightweight, free PC cleaner for Windows 10 and 11 that finds and removes temp files, browser caches, Windows Update leftovers, and crash dumps in one click. No account needed, no paid tier, no invented "1,000 problems detected" scare tactics.
Your Windows PC accumulates junk files automatically. Every time Windows updates, your browser loads a page, or your system crashes, temporary files pile up in hidden folders. After a few months or years, these invisible files consume gigabytes of disk space.
A cleanup tool finds these orphaned files in the places where they actually live—`%TEMP%`, `C:\Windows\Temp`, browser cache folders, Windows Update downloads, and the Recycle Bin—and removes them safely. SwiftClean shows you exactly which folders it will touch and how many megabytes it finds before you click Clean.
Most cleanup tools either hide their features behind a paywall or use scare tactics to pressure an upgrade. SwiftClean does neither. It reports honest numbers, leaves your documents and saved logins untouched, and installs quickly for Windows 10/11.
**Windows temporary files** — Both `%TEMP%` and `C:\Windows\Temp`. Older machines accumulate years of orphan junk here.
**Browser caches** — Chrome, Edge, Firefox, Opera, Brave, and Yandex. Cache data only—your saved passwords, cookies, and logins stay intact.
**Recycle Bin** — Emptied using the same safe method Windows File Explorer uses, so deletions behave exactly as expected.
**Windows Error Reporting dumps** — Stale crash reports nobody will ever review.
**Windows Update leftovers** — The `SoftwareDistribution\Download` folder, often the single biggest offender on patched machines.
**Thumbnail cache** — Explorer's cached thumbnails; a fresh database rebuilds on demand.
**Startup programs** — Disable autostart entries with a reversible registry backup so you can undo any change.
**Custom folders** — Point the tool at any folder (old Downloads, game cache, etc.) and include it in the next scan.
Most cleanup utilities bury useful features behind a paywall or pump up numbers to scare users into upgrading. SwiftClean is genuinely free—no paid tier, no nag screens, no subscription. The MIT license covers personal and work use.
It installs easily on Windows 10/11. Download the zip, run the setup, and you are done.
The numbers are honest. You see the actual megabytes found before cleanup and the actual megabytes freed after. No theater about "1,000 registry problems detected."
It doesn't need internet, doesn't phone home, and doesn't require an account. Offline operation means your cleanup stays private.
Yes. No paid tier, no subscription, no pro nag screen. The MIT license covers personal and work use.
Yes, tested on Windows 10 and 11 (64-bit). Windows 7 and 8 also run it fine.
Standard-user mode handles your profile's temp folders and browser caches. Admin mode (via UAC) unlocks `C:\Windows\Temp` and the Windows Update cache—optional.
It targets only known-safe junk: temp directories, browser cache subfolders, Recycle Bin, error dumps, and update downloads. Documents, photos, and installed programs are never touched.
No account, no email, no internet. Download the zip, run the setup, clean — quick download for Windows 10/11.
