    The real download lives on windirstat.net. Look-alike domains and search ads are the most common trap.

  • Skip mirrors

    Download portals can wrap installers in adware or old versions. You never need them for this app.

    If the publisher lists a checksum, compare it with our in-browser checker before running the file.

  • Watch the installer

    Untick extras, browser changes or trials you did not ask for.
