Windows 11 Weather App Uses 5x RAM & Shows Ads! macOS Beats It! (2026)

Windows 11's Weather app is a prime example of the challenges faced by Microsoft in balancing functionality, user experience, and revenue generation. While it offers detailed weather data and live radar overlays, the app's heavy reliance on RAM and the presence of ads have sparked debate among users and industry experts alike.

The Weather app's excessive RAM usage is particularly concerning. With a single native process using 246.7MB of memory on macOS, it's clear that the Windows 11 app's web-based architecture is to blame. The app's nine separate sub-processes running under Weather, all Chromium process names, contribute to its high memory consumption, even when idle. This inefficiency is a stark contrast to Apple's Weather app, which demonstrates that a native process can deliver the same level of detail without the same resource-intensive approach.

The inclusion of ads in the Weather app further adds to the controversy. While weather forecasting is a profitable venture, the app's integration with MSN, a Microsoft-owned service, raises questions about the company's commitment to user privacy and the potential for data collection. The app's store listing, which recommends signing into a Microsoft account, only adds to the suspicion.

The solution lies in Microsoft's ongoing efforts to modernize its inbox apps. By dumping legacy Win32 and WebView2 code in favor of WinUI, Microsoft can create a more efficient and user-friendly experience. A native, ad-free Weather app rebuilt in WinUI would not only address the RAM issue but also set a precedent for third-party developers, encouraging them to move away from web wrapper apps.

However, the challenge lies in Microsoft's ability to balance its various interests. While the company has committed to building fully native apps, the MSN-branded Weather app may be an exception. The company's stubbornness with Microsoft accounts and its focus on profit margins could hinder the adoption of a truly native, ad-free Weather app. Nonetheless, the push for a faster and ad-free Windows 11, coupled with the ongoing modernization efforts, suggests that Microsoft is listening to user feedback and taking steps to improve the overall user experience.
