MSDL replicates the session flow that Microsoft uses to serve ISO download links — identical to the approach used by [Rufus/Fido](https://github.com/pbatard/Fido). You get the exact same signed CDN URL Microsoft would give you, just without the browser requirement.
- ✅ Direct Microsoft CDN links — no proxying of actual file data
- ✅ 38 languages per release
- ✅ 38 languages per consumer release
- ✅ ARM64 + x64 + x86 support
- ✅ Windows Server 2016–2025 and Windows 11 Enterprise evaluation ISOs
- ✅ No account, no browser lock, no ads, no tracking
- ✅ Links expire in 24 hours (Microsoft's standard behaviour, not a limitation)
- ✅ Consumer links expire in 24 hours (Microsoft's standard behaviour, not a limitation)
