The Windows 11 Weather app is under fire for eating up too much memory. According to reports, the app, which is built on MSN’s web platform, uses more than 1GB of RAM when opened and can spike to 1.5GB to 1.6GB during simple actions like zooming or scrolling. For comparison, Apple’s Weather app on macOS stays under 250MB.
The problem comes from Microsoft’s use of WebView2, a Chromium‑based framework that spawns multiple processes. This design not only drives up memory use but also adds ads inside the forecast feed.
On PCs with 8GB of RAM, the Weather app can take nearly 20 percent of available memory. That forces Windows to rely on SSD paging, which slows down performance.
Even when idle, the app sits at 500MB to 600MB. For budget laptops and desktops, this is a big issue. Microsoft promised Windows 11 would run better on low‑end hardware, but the Weather app still hasn’t been optimized. Some users suggest disabling the app in the background or uninstalling it to save resources.
Microsoft said it wants to build more native apps to improve efficiency. But it’s not clear if MSN‑based apps like Weather will be rebuilt.

The impact is clear, though. Windows 11’s Weather app shows how far Microsoft still has to go in making the system lighter and more efficient for entry‑level PCs.
