As the functionalities of operating systems continue to proliferate, users are increasingly prioritizing the performance and user experience of pre-installed system applications. Recent technical assessments have uncovered that the 'Weather' app, which comes pre-loaded on Windows 11, gobbles up more than 1.2GB of memory even when it's just idling in the background. This is nearly five times the memory consumption of the default weather application on macOS, which hovers around 247MB. Moreover, the presence of numerous commercial advertisements within this app—pre-installed on a paid operating system—has ignited a wave of controversy.
