微软Windows 11的内置天气应用存在严重的内存泄漏问题。[1]测试数据显示，该应用在显示天气预报时可占用超过1.2GB的RAM，内存使用通常从1GB开始，空闲时降至500-600MB，进行基本操作时可升至1.5-1.6GB。[1]在配备8GB内存的电脑上，这个应用可占用近20%的系统内存。[1]
这款天气应用是基于WebView2框架构建的MSN Weather网页应用，通过运行多个Chromium子进程来工作，导致内存占用居高不下。[1]相比之下，苹果macOS原生天气应用的内存占用不到250MB。[1]此外，该应用内还包含广告，赞助内容被直接嵌入天气预报源中。[1]
Microsoft's built-in Weather application for Windows 11 exhibits significant memory inefficiency, consuming more than 1.2 GB of RAM when displaying weather forecasts.[1] Memory usage typically starts at around 1 GB, fluctuates between 500–600 MB during idle periods, and can spike to 1.5–1.6 GB during basic operations.[1] On systems with 8 GB of total RAM, the Weather app can occupy nearly 20 percent of available memory.[1]
The application's heavy resource consumption stems from its architecture, as it is built on the WebView2 framework and runs multiple Chromium subprocesses rather than using native Windows code.[1] For comparison, Apple's native Weather application on macOS uses less than 250 MB of RAM, making Microsoft's Weather app roughly five times more memory-intensive.[1] The Weather application also contains advertisements, with sponsored content directly embedded within weather forecast feeds.[1] Microsoft executive Rudy Huyn has indicated that the company hopes to develop more native Windows applications in the future.[1]
