Windows 11's built-in weather app hogs more than 1.2 gigabytes of RAM just to tell the forecast — memory-sucking web wrapper filled with ads masquerades as an actual application

Windows is in a tough spot right now, with years of neglect and stagnation reaching a boiling point with customers. Lack of optimization, bloat, ads, forced AI slop, and persistent tracking have forced Microsoft to admit its missteps and commit to fixing the OS at large. Windows Latest's new testing shows that the built-in weather app is a perfect representation of the state of Windows. The "app" consumes up to 1.2GB of RAM while idling, and it serves up a bunch of ads while you check the temperature.MSN Weather is the default weather app that ships with Windows, which explains why it's filled with promotions throughout, despite being part of a paid OS. To be clear, the app looks very modern and has all the data you could ask for, such as live radar overlays, hourly wind and precipitation breakdowns, air quality index, and moon phases. It's also accurate because the data is sourced from a bunch of different providers across the world, but mostly Foreca.

But the comparison falls apart when you look at what the competition is offering. Apple's native weather app on macOS is just as beautiful, detailed, and accurate, yet it's free of ads. It also only consumes about 250MB of memory to show all that data, so 5x less than Windows. This is because MSN Weather is technically not even an app to begin with; it's a web wrapper that's pinging a bunch of browser tabs in real-time.When the author clicked on the Task Manager entry for MSN Weather, they saw 8 Chromium-based subprocesses, confirming that they're just looking at a website being rendered via WebView 2. For context, native Windows apps are supposed to adhere to the WinUI framework, which the company is slowly adopting over Win32 and UWP. Microsoft is committed to updating all the native apps Windows ships with to Win32, which should significantly improve their optimization, but we don't know if the ads will suddenly disappear as well.
