Microsoft used AI to help build Windows 11’s new speed test
A Windows 11 built-in speed test now in Insider testing was made with an AI-assisted, human-guided workflow, Microsoft’s design lead said.

Microsoft is testing a built-in internet speed test in Windows 11 that was made with AI help, per a Windows Central report built around a company design lead’s account.1
The feature checks a PC’s connectivity without opening a browser or a separate app and is already in testing with Windows Insiders. Windows 11 already had a speed-test control, but that shortcut only launched Bing’s test in a web browser. The new tool is built in, so it reads as part of the OS rather than a browser hand-off.1
Marcus Ash, lead of Design and Research across Windows & Devices, said the work came from an agentic AI workflow guided by a real person. “This is where I see a lot of potential in AI,” Ash said. He pointed to agentic workflows and WinUI 3 for more integrated Windows experiences, a faster path from idea to customer value, and results he described as free of AI slop.1
Seen it before: a system button that only opened a web page was always a temporary badge on a permanent problem.
The addition has been well received online. Windows Central’s Mauro Huculak said Windows 11 needs more features like this. The same report sets the project against “vibe coding,” often blamed for low-quality AI work, and says Microsoft leaders treat AI as a tool beside people that still depends on human expertise—the posture behind the Copilot name on many of the company’s AI products.1
What you should do: Windows Insiders can exercise the built-in test in current flights; there is no wider release step described in this account.
Our read: A native speed test is a small cleanup of an awkward Bing shortcut and an early, low-stakes sample of AI inside Microsoft’s Windows build process with a person still steering. Warm Insider-era reaction is a start. The real test is whether the same workflow still looks clean on harder OS work, and how far beyond the Insider ring the tool actually goes.
