Source: Microsoft introduces flighting for Windows Server insiders

I have yet to meet anyone using insider builds, let alone an expensive Windows Server license for an insider build. Free licensing for insiders would be a boon for Microsoft, provided the licensee can pass some basic requirements (testing, not in prod, etc). But it’s been some years since Microsoft ditched the whole Technet license thing and I don’t think we’ll ever see holistic QA from Microsoft, not when their testers all probably write malware after discovering flaws in early releases. 🤣
