Microsoft marked the Windows Insider Program’s 11th anniversary today with a thank‑you from program lead Amanda Langowski and a set of custom wallpapers for desktop and phone designed with the Windows Design team (see the 10th anniversary).
What’s new with the Windows Insider Program
The anniversary post celebrates millions of Insiders who preview builds, share feedback, and help guide Windows development, with a renewed commitment to innovate for what’s next. Microsoft released special 11th‑anniversary wallpapers as part of its long‑running tradition of commemorative Insider backgrounds for both desktop and mobile.
“Over the past 11 years, millions of Windows Insiders have previewed our developing experiences, shared invaluable feedback, and inspired us to meet what customers need today—and to keep evolving for what’s next.” -Amanda Langowski, on behalf of the entire Windows Insider Team
The post reiterates that participation—installing preview builds, using Feedback Hub, and joining community discussions—directly shapes Windows features and improvements.
Why it matters
The Windows Insider Program has been central to Windows’ development since its 2014 debut, enabling enthusiasts, IT pros, and developers to test pre‑release features and provide direct feedback. Microsoft emphasizes the program’s role in aligning Windows with real customer needs today and evolving requirements tomorrow through continuous community‑driven input.
How to get the wallpapers
Custom 11th‑anniversary backgrounds are available now for both desktop and phone via the official announcement and are presented as a thank‑you to Insiders. Microsoft frames the wallpapers as part of an annual tradition celebrating Insider milestones alongside community recognition.

Join or keep contributing
New and returning Insiders can opt into preview builds and manage participation through Windows settings and the Insider hub while continuing to file feedback in Feedback Hub. Microsoft also references using Settings and Insider controls for feature rollouts, consistent with recent Insider build guidance that points to Settings > Windows Update flows.
