Krypt Cleaner Guide: Free PC Cleaner to Free Up Disk Space

• One-click Health Check that shows how much space you can reclaim.
• System junk: temp files, update caches, shader caches, crash dumps and the Recycle Bin.
• Browser cleanup across major browsers: cache, cookies, history, sessions and other data. Sensitive data is always opt-in.
• App and game caches for popular apps, launchers, communication tools and game platforms.
• Privacy cleanup: recent documents, Run history, Explorer search history and typed URLs.
• Disk tools: SSD and HDD optimisation, storage analysis, a duplicate finder and drive health.

Krypt Cleaner is Windows-only.

1. Open the Krypt Cleaner page on krypt.cc. That page is the only official download; copies re-uploaded elsewhere can be modified.
2. Click the Windows download button.
3. Read and accept the Software Download Terms in the prompt. The file downloads as soon as you agree, and you won't be asked again for that tool until the terms change.
4. Optional but sensible: upload the file to VirusTotal before you run it.

Windows

1. Run the installer you downloaded.
2. If Windows SmartScreen says "Windows protected your PC", click More info, then Run anyway. Krypt builds aren't code-signed yet, so SmartScreen treats them as unrecognised apps. That warning is about the missing signature, not about anything it found in the file.
3. Follow the installer, then launch Krypt Cleaner from the Start menu or the desktop shortcut.

Some system areas can only be cleaned with administrator rights, so Windows may ask for them.

1. Close your browsers and games first. Files in use are locked and can't be cleaned. Krypt Cleaner reports them rather than skipping silently.
2. Run the Health Check to see what can be reclaimed.
3. Review each area and its risk label. Start with the low-risk ones: temp files, crash dumps, update caches.
4. Leave cookies, sessions and history unticked unless you want to be signed out of sites. They are opt-in for a reason.
5. Clean, then run the Health Check again to see what you got back.

• Temp files: leftovers apps create while working and often forget to delete.
• Update caches: downloaded Windows update files that have already been installed.
• Shader caches: compiled graphics shaders. They are rebuilt automatically, so the first launch of a game afterwards may stutter briefly.
• Crash dumps: memory snapshots from past crashes, useful only if you are debugging one.
• Browser cookies and sessions: these sign you out of websites.
• Privacy traces: lists of recently opened files and typed commands. They're backed up first, so this can be rolled back.

The duplicate finder never deletes automatically: you choose which copy stays. Before you delete, check both locations. Two identical files in different project folders may both be needed by the apps that use them, so be most careful inside program and game folders.

• Use storage analysis to find what's really filling your drive. It's often one folder of videos or game installs, not junk.
• Check drive health now and then, especially on an older HDD.
• Cleaning once a month is plenty for most PCs.
• For performance rather than space, see Krypt Tweaker.
