Windows Server vNext build 25227 ISO released to Windows Insiders

Microsoft has released a new build of the Windows Server Insider Preview. Build 25227 is available to download as an ISO from the Windows Server Insider website along with a VHDX. Even though this uses the same underlying kernel as the Windows 11 Dev build development, as per usual, there's no changelog to speak of, so it's unclear what's new in this build.

The branding for Server has still not been updated and remains as Windows Server 2022 in the preview. In addition, Microsoft is asking Insiders to refer to these builds as vNext rather than Windows Server 2022 which is already in the market.

Build 25227 of Server contains just one Known Issue, listed below:

The Languages and Optional Features Preview fails to enable sporadically with an error "Something didn't go as planned. No need to worry-undoing changes. Please keep your computer on"

Available Downloads:

• Windows Server VNext Preview in ISO format in 18 languages,
  and in VHDX format in English only.
• Windows Server VNext Preview VHDX
• Microsoft Server Languages and Optional Features Preview
• Windows Admin Center 2110.2 Preview

Keys are valid for preview builds only:

• Server Standard: MFY9F-XBN2F-TYFMP-CCV49-RMYVH
