How we check compatibility
We do not test every application on every Windows version. Instead, we record what each project’s official website, download page or release notes say about the current release.
Third-party download sites often list Windows versions that a project no longer supports, so we do not treat them as evidence.
Windows 7 and 8.1 no longer receive regular security updates from Microsoft. If you still use them, prefer software that is actively supported and keep your data backed up.
