The reasoning behind this verdict

Analyst conclusion

None of the 71 antivirus engines that checked it flagged this file, including every major antivirus engine. It has circulated widely for over five years with thousands of distinct submitters. Its signature claims HeiDoc but failed verification because the certificate expired. That is common for older builds, but it means the signature cannot confirm the publisher.

Where this verdict could be wrong2 caveats
  • The publisher's certificate has expired, so the signature cannot confirm who built this copy.
  • Some community researchers have labelled the file suspicious, although no antivirus engine agrees and those notes are untrusted context.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Questions & answers

Short answers to the 7 questions people ask most about this file.

Is Windows-ISO-Downloader.exe safe?
We found nothing harmful in Windows-ISO-Downloader.exe. None of the 71 antivirus engines that checked it flag it. Run it only if it came from the developer's own website or an official app store.
What is Windows-ISO-Downloader.exe?
Windows-ISO-Downloader.exe is a Windows program, about 7.3 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Jan 7, 2021.
How many antivirus engines detected Windows-ISO-Downloader.exe?
None of the 71 antivirus engines that checked it flag Windows-ISO-Downloader.exe. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
Is Windows-ISO-Downloader.exe digitally signed?
It carries a signature in the name of HeiDoc V.O.F. that could not be verified. Malware sometimes copies or steals a company's signature, so this does not mean that company made it.
What is the SHA-256 hash of Windows-ISO-Downloader.exe?
The SHA-256 fingerprint of Windows-ISO-Downloader.exe is d9e52b0dbb5d3540016497c913e4186433c2ecd14e359eb841d5d93c8b021aef, and its MD5 is 42be2387ea24923622219a33c504c091. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
Is it safe to run Windows-ISO-Downloader.exe?
We found nothing harmful in Windows-ISO-Downloader.exe. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of Windows-ISO-Downloader.exe?
This report reflects the scan on Sep 5, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
