The Windows Insider program is expanding its confines once again, this time moving to include Windows Server. Microsoft announced on its TechNet blog (via OnMSFT) that frequent Windows Server build will become available to download for Windows Insiders willing to test them starting this summer.

Windows Server is now a part of the Windows Insider program

From Microsoft:

Today I am pleased to announce that Windows Server is joining the Windows Insider program! Starting this summer, regular and frequent builds of Windows Server (including container images) will be available to all Windows Insiders who want to download and test them. As Dona Sarkar, who runs the Windows Insider program, recently said of the Insider community, "These are the biggest fans of Windows I've ever seen in my whole life." With the addition of Windows Server, the community has even more reasons to be a fan.

This is the second big expansion for the Insider Program in recent months. In April, Microsoft first opened up its new Windows Insider Program for Business as a dedicated program to let IT administrators provide feedback without it getting lost in the noise of the entire Insider community.
