Just like Windows consumer builds for Insiders, Microsoft releases Windows Server preview builds on a regular basis too. Just last week, it rolled out Windows Server VNext Preview build 25099 to those registered as Insiders.
However, unlike Windows 10 and Windows 11 builds which are released to Insider channels via Windows Update, Windows Server preview builds are provided to registered users via ISO files. That may be set to change soon as Microsoft is now fielding interest from Windows Server admins about whether they would like preview builds flighted to them like Windows client versions.
In a forum post, Microsoft has shared a link to a survey that Server admins can fill to provide feedback to the company about whether they would like preview builds flighted to their test devices. The motivation behind this approach is to "facilitate build-to-build upgrades" but Microsoft has noted that for this to be functional, the Windows Server instance would need to be connected to the internet. A caveat is also that Windows Server Update Services (WSUS) does not currently support flighting preview builds in this manner. It is important to note that the current upgrade method will not be deprecated and ISOs will still continue to be offered.
The survey is pretty short and consists of only six questions. These questions revolve around how frequently admins install preview builds, interest in installing flighted builds without WSUS support, and how long respondents have been enrolled in the Insider program. The survey closes on May 18, 2022.
