The built-in Weather app for Windows 11 consumes more than 1.2 GB of RAM to provide local weather forecasts [1].
This high memory usage can slow down system performance for users, particularly those with limited hardware resources, by diverting critical system memory to a simple utility app.
Technical analysis shows the application is a web-wrapper rather than a native program [1]. It functions by launching several Chromium subprocesses to fetch forecast data and serve advertisements to the user [1], [2]. This architecture explains why the app requires significant resources to operate.
When compared to competing software, the resource drain is substantial. The Windows 11 Weather app uses about five times more RAM than the macOS Weather app [2]. Other reports confirm the memory footprint remains over 1 GB [3].
Because the app masquerades as a standard application while running a full browser engine in the background, it continues to draw resources that would typically be reserved for more demanding software. The inclusion of ad-serving processes further increases the load on the system's memory [1], [2].

The reliance on web-wrapper architecture for system utilities reflects a broader industry trend of prioritizing ease of development and ad integration over native performance. By using Chromium subprocesses, Microsoft can update the app's content and monetization strategy instantly via the web, but this shifts the performance burden to the user's hardware.
