Microsoft's Weather App Eats 1.2GB RAM! Why is it So Heavy? (2026)

In a surprising revelation, Microsoft's Weather app has been found to consume an astonishing amount of system resources, specifically RAM, even when it's just sitting open on a forecast screen. This unexpected behavior has sparked curiosity and raised questions about the app's design and Microsoft's approach to resource management.

The app, which is a standard feature in Windows 11, offers a range of detailed weather tools and data. However, its memory consumption, reaching up to 1.2 GB of RAM, is a cause for concern, especially when compared to Apple's Weather app on macOS, which achieves similar functionality with a fraction of the resource usage.

The App's Design and Resource Usage

The MSN Weather app's interface is modern and functional, but its resource-intensive nature is a notable drawback. The app's high memory usage can be attributed to its Chromium-based subprocesses, suggesting a web wrapper design rather than a fully native application. This design choice explains the app's heavy memory footprint, which is particularly concerning on systems with limited RAM.

Advertising and User Experience

Adding to the frustration, the Windows Weather app also displays advertisements. While Microsoft may argue that ads help offset the cost of delivering weather data, it's a point of contention for users who have already paid for a Windows license. This practice raises questions about the balance between providing a useful service and respecting user expectations.

Microsoft's Performance Goals and Reality

Microsoft has been vocal about its commitment to improving Windows 11's performance, reliability, and memory usage. However, the Weather app's resource consumption highlights the gap between the company's goals and the reality of some Windows utilities. Despite Microsoft's plans to update and optimize the apps included with the operating system, it's unclear whether this will extend to MSN-branded services like Weather and News.

A Browser-Based Approach

The Weather app's behavior, as observed in Task Manager, resembles a small browser session rather than a lightweight app. This is due to Microsoft's use of WebView2, a framework for embedding web content in Windows apps. While this approach has its advantages, it also results in higher resource usage, which is not ideal for a default desktop app.

Conclusion

Microsoft's Weather app serves as a reminder that even seemingly simple utilities can have a significant impact on system resources. While the app offers a visually appealing and data-rich experience, its resource-intensive nature and advertising raise questions about Microsoft's approach to default apps. As Microsoft continues to optimize Windows 11, it will be interesting to see if and how the Weather app is addressed in future updates.
