Windows 11 KB5083769 brings built-in internet speed test to all 25H2, 24H2 users

Back in September of 2025, right before the release of Windows 11 version 25H2, Microsoft first started testing an inbuilt internet speed test feature on the OS. At the time details were scarce and we had to wait until the February 2026 C-release KB5077241, when Microsoft began to roll the update out to non-insiders.

Thus technically the internet speed test should have been out earlier with the March 2026 Patch Tuesday, but that did not happen, or at least it did not roll out to everyone. So if you did not get it last time, the newer April 2026 Patch (KB5083769) should have you covered as Ookla announced this week that the speed test feature is "now rolling out broadly to all eligible Windows devices".

The company alongside Microsoft announced their partnership this week to offer Speedtest directly into Windows 11. The integration allows users to run internet diagnostics from the taskbar or quick settings without needing to open a browser or third-party app. This new development is based on earlier efforts when Speedtest was integrated into Bing.

By right-clicking the network icon or opening Wi-Fi and cellular quick settings, users can measure download and upload speeds, latency, and jitter. Ironically, the option still opens a web instance on Bing, except your effort is reduced as you no longer have to go to a browser and type in "speed test" or something like that on the search engine.

If you are wondering about how this Speedtest works, the tests rely on Ookla’s global infrastructure and are based on Speedtest Web SDK, introduced in 2020, which has enabled service providers and enterprises to embed Speedtest directly into websites and such. The SDK is built in JavaScript and offers a customizable interface allowing companies like Microsoft to tailor the experience to their users' needs.
