How to tell whether a download page is official

Basic check order

1. Start from the vendor, open-source project, or official store page rather than a search ad or file mirror.
2. Compare the visible domain, final redirected domain, publisher name, and product name before downloading.
3. Look for stable release pages, version notes, official stores, package managers, or signed release artifacts when available.
4. Avoid repackaged installers, bundled download managers, and pages that hide the publisher behind a generic download button.
5. For work devices, also check license terms, business-use limits, account ownership, and data handling before installation.

Cautions and operating tips

• Official projects may use GitHub, Microsoft Store, App Store, package managers, or CDN hosts; the key is whether the path is linked from the official project.
• A HTTPS lock icon only means the connection is encrypted. It does not prove the download is from the real vendor.
• When in doubt, use the vendor documentation or release page rather than a third-party download portal.
