It’s all about your feedback! 

Use the Feedback Hub app to provide feedback on Windows Server builds. Feedback Hub comes pre-installed on Windows 10. Register a Windows 10 device with the Windows Insider or Windows Insider for Business programs. Open the Feedback Hub application. Choose the Server category and then the appropriate subcategory for your feedback. Please indicate what edition and build number you are providing feedback on. The Feedback Hub app cannot scan a server for diagnostic information, however you may manually attach screenshots or other files to your feedback entry.

We encourage you to visit the Windows Server Insiders space on the Microsoft Tech Communities forum to collaborate, share and learn from experts.
