server-side flags

About this tag
The server-side flags tag on WindowsForum.com covers discussions about Microsoft's use of controlled feature rollouts and A/B testing in Windows 11 Insider Preview builds. Recent threads highlight how Microsoft employs server-side flags to gradually enable visual changes, such as the shift from green to blue progress bars in File Explorer during Dark Mode and the extension of dark theme support to legacy file-operation dialogs.

The tag is relevant for Windows enthusiasts and IT professionals tracking the evolution of Windows 11's user interface through controlled experiments.
