TL;DR
The built-in Weather app in Windows 11 is reportedly consuming over 1 GB of RAM, according to user reports and technical analyses. Microsoft has not yet commented on the issue, which could impact system performance.
Multiple users and technical assessments have confirmed that Windows 11’s built-in Weather app is consuming more than 1 gigabyte of RAM, a substantial amount for a lightweight application.
This issue raises concerns about resource management within Windows 11, especially on systems with limited RAM, and could affect overall performance and stability.
According to reports from users and independent testers, the Windows 11 Weather app, which is designed to provide weather updates, is using over 1 GB of RAM during regular operation. This behavior was observed across multiple devices, regardless of hardware specifications, suggesting a potential software issue rather than hardware limitations.
Microsoft has not yet issued an official statement regarding these findings. The app’s high memory consumption appears to be linked to background processes and data caching mechanisms, but the exact cause remains unclear.
Experts warn that such high RAM usage by a built-in app could lead to reduced performance, especially on devices with less than 8 GB of RAM, affecting user experience and system stability.
Implications for Windows 11 Users and System Performance
The excessive RAM usage by the Weather app highlights potential inefficiencies in Windows 11’s resource management, which could impact a broad user base, particularly those with limited system memory. If unaddressed, this issue might cause slower performance, increased battery drain, or system instability.
For enterprise environments and users relying on lightweight hardware, such as laptops and tablets, this could mean needing to disable or uninstall the app to maintain optimal performance. The situation underscores the importance of ongoing system optimization and transparency from Microsoft regarding resource usage of pre-installed applications.

Background on Windows 11 Built-in Apps and Recent Performance Issues
Windows 11, released in October 2021, introduced a redesigned interface and several new features, including integrated apps like Weather. Over time, users and experts have reported various performance concerns, including high CPU and memory usage from some default applications.
While Microsoft has generally improved app efficiency through updates, this recent report of the Weather app consuming more than 1 GB RAM marks a notable deviation from expected behavior. Similar issues have been observed in other Windows 11 apps, raising questions about overall system optimization.
“We are investigating reports related to app performance and will provide updates if necessary.”
