How do I know this exe is legitimate?

Confirm the MZ signature via the [File Signature Checker](/en/tools/file-signature-checker), run a [VirusTotal](https://www.virustotal.com/) scan, and compare the SHA-256 hash with what the official distributor publishes. If any step is shaky, don't run it.

Downloaded EXEs carry a Zone.Identifier (ADS) mark; antivirus may flag them until you Unblock-File.
