Windows 11's built-in Weather app wastes more than 1 GB of RAM - Notebookcheck News

Microsoft has been working to make Windows 11 more efficient on PCs with limited RAM, but one of its own built-in applications appears to be working against that goal. According to tests published by Windows Latest, the operating system's Weather app can consume more than 1 GB of memory despite performing a relatively simple task.
Windows Latest reports that the app exceeded 1.2 GB of RAM while displaying a weather forecast, with no intensive interaction from the user. Wccftech observed similar behavior, noting that memory usage typically starts at around 1 GB, drops to roughly 500–600 MB when idle, and can climb to 1.5–1.6 GB during basic actions such as zooming or navigating the interface. On a PC equipped with 8 GB of RAM, that means the application alone may occupy nearly 20% of the system's memory.

Windows 11's Weather app consumes more than 1 GB of RAM.
By comparison, Apple's native Weather app on macOS reportedly uses less than 250 MB of RAM under similar conditions, giving Microsoft's implementation a memory footprint roughly five times larger.

According to Windows Latest, the high memory consumption is due to the fact that Weather is not a fully native Windows application. Instead, it is essentially an MSN Weather web app built on Microsoft's WebView2 framework. Task Manager shows multiple Chromium-based subprocesses running simultaneously, which contributes to the unusually high RAM usage.
The issue is unlikely to affect high-end PCs with 32 GB or more of RAM, but it could have a noticeable impact on entry-level systems. On computers with 8 GB or even 16 GB of memory, launching the Weather app may increase memory pressure enough for Windows to rely more heavily on the page file, potentially making the system feel less responsive.
The application also includes advertising within its interface. According to Windows Latest, sponsored content is embedded directly into the forecast feed, appearing alongside weather cards in a similar visual style. While Microsoft licenses weather data from multiple providers — including Foreca, the European Centre for Medium-Range Weather Forecasts (ECMWF), and other regional meteorological services — the presence of ads in a built-in Windows application has attracted criticism.
The findings also appear to contradict Microsoft's recent efforts to improve Windows 11's efficiency. The company has been updating several built-in applications and has repeatedly said it wants the operating system to perform better on lower-end hardware. Microsoft executive Rudy Huyn has also stated that the company intends to develop more fully native Windows applications in the future, although it remains unclear whether MSN-branded applications such as Weather will eventually be rebuilt using WinUI.
