Today, Microsoft is releasing ISO images for Windows 10 version 21H1 to Windows Insiders. It’s meant for those on the Beta channel, and will start you off at Windows 10 build 19043.
If you’ve been waiting to test out Windows 10 version 21H1 previews but were waiting until you can do a clean installation, today is your day. Microsoft released ISOs of Windows 10 Insider Preview build 19043 today, as that’s the build that’s in the Beta channel. But even to call this a « preview » of Windows 10 version 21H1 is a stretch. The feature update itself is an enablement package, which is this tiny file that bumps up the build number by one and lights up some features.
