Facepalm: Microsoft's default Weather app in Windows 11 can use nearly 1.2 GB of RAM while sitting open on a forecast screen, according to testing by Windows Latest. The app doesn't need to be actively used to reach that level of memory consumption. The report found that MSN Weather launches as many as nine Chromium-based subprocesses, suggesting the app is built around a web wrapper rather than as a fully native application. That design helps explain why a basic system utility can use so much memory.
MSN Weather is the standard weather app included with Windows 11. It provides a detailed set of tools, including live radar, hourly forecasts, wind and precipitation data, air-quality readings and moon phases. The data comes from several weather providers, with Foreca serving as a primary source.
The app's interface is modern and works smoothly, but still, the level of resource use stands out when compared with Apple's Weather app on macOS, which uses about 250 MB of RAM while providing similar forecast details. That is about five times the RAM usage for the built-in Windows alternative.
