Windows 11 weather app memory usage has crossed an embarrassing milestone: Microsoft’s built-in Weather app now consumes more than 1.2 gigabytes of RAM just to display a five-day forecast. That’s not a typo, and it’s not a virus — it’s an architectural choice baked into the app itself. If your PC has ever felt sluggish after glancing at tomorrow’s rain chances, you’ve found the culprit. In this guide we’ll break down exactly why the weather app memory footprint is so outrageous, and walk you through every practical fix available right now.
What Is the Windows 11 Weather App, Really?
Most people assume that a built-in Windows app is a lean, native application compiled specifically for Windows. The Weather app is not that. Under the hood, it is a WebView2 wrapper — essentially a stripped-down instance of Microsoft Edge’s Chromium engine loading the MSN Weather website inside a frame that looks like a desktop app. When you open Weather, Windows isn’t running a tightly optimised piece of software; it’s spinning up a near-full browser, loading a commercial web page packed with display advertising, data trackers, and JavaScript widgets, then presenting the whole thing inside a thin app shell.
This design pattern — wrapping a website in a native-looking container — has a name in the developer community: a web wrapper or Electron-style app. The difference here is that Microsoft is the OS vendor shipping it as a default system app, which raises expectations significantly. An independent developer shipping a bloated app is an inconvenience. The company that makes the operating system shipping one is a policy decision that affects hundreds of millions of machines.
Why Windows 11 Weather RAM Usage Is So High
The Windows 11 weather RAM problem stems from three compounding factors working together:
- Chromium’s multi-process architecture: WebView2 inherits Chromium’s process model. Open Task Manager and you’ll typically see eight to nine separate Microsoft Edge WebView2 Runtime processes spawned by a single Weather app session. Each process carries its own memory overhead.
- Advertising payload: The MSN Weather page loaded inside the wrapper is a commercial page with banner ads, sponsored content tiles, and third-party ad-tech scripts. Each ad unit triggers additional resource fetches, JavaScript execution, and GPU compositing — all of which translate directly into RAM.
- No memory ceiling: A native Windows application typically declares its resource requirements. A Chromium-based wrapper does not. The WebView2 runtime will allocate as much RAM as the page demands, and a heavily monetised weather page demands a lot.
Independent testing reported by Tom’s Hardware confirmed peak usage reaching 1.2GB to 1.6GB, with nine separate WebView2 processes visible in Task Manager. For context, the equivalent macOS Weather app — a genuine native application — uses around 200MB. The Windows version consumes roughly five times as much for the same data.
Windows Weather Memory Fix: Step-by-Step Solutions
The good news is that you don’t have to live with this. These fixes range from a two-minute tweak to a full replacement strategy — pick what suits your comfort level.
1. Disable Background App Activity
The Weather app can run in the background even when you’re not using it, silently consuming RAM to keep forecasts up to date in the Widgets panel. Stopping this reclaims memory without losing access to the app when you actually need it.
- Open Settings → Apps → Installed apps.
- Search for Weather and click the three-dot menu → Advanced options.
- Under Background apps permissions, set to Never.
- Also toggle off Let this app run in the background if the option is present.
This alone can recover several hundred megabytes on machines that had Weather set to refresh continuously.
2. Remove the Weather Widget from the Taskbar
The Widgets button on the Windows 11 taskbar is a persistent background service that pre-loads personalised content — including Weather — whether you’ve opened the full app or not. Removing it cuts one of the main triggers for background Weather activity.
- Right-click the taskbar → Taskbar settings.
- Toggle Widgets off.
On some machines this step alone reduces overall system RAM usage by 200MB–400MB because the entire Widgets host process shuts down.
3. Uninstall the Weather App Entirely
Windows 11 lets you uninstall most built-in apps directly from the Start menu. Right-click the Weather tile → Uninstall. If you want to be thorough, open Windows PowerShell (Admin) and run:
Get-AppxPackage *BingWeather* | Remove-AppxPackage
This removes the app for the current user. The command is reversible — the app can be reinstalled from the Microsoft Store at any time.
4. Switch to a Lightweight Weather Alternative
Uninstalling the built-in app doesn’t mean going without weather data. These alternatives provide accurate forecasts for a fraction of the RAM cost:
- weather.com or weather.gov in your browser: Pin a tab in your existing browser session. Since your browser is already open, there’s zero extra RAM overhead for a second Chromium instance.
- WinWeather (Microsoft Store): A community-built lightweight weather app using native WinUI controls rather than a web wrapper.
- Taskbar clock weather integration: Third-party tools like ElevenClock can display current conditions directly in the system clock tooltip — no separate app needed at all.
- Search widget search: Typing a city name followed by “weather” in the Windows Search bar pulls a real-time weather card without opening any app.
5. Audit and Manage All WebView2 Processes
The Weather app isn’t the only Windows 11 application built on WebView2. The Teams, Widgets, and some Office features use the same runtime. Open Task Manager → Details tab, then sort by Memory (private working set). Any process named msedgewebview2.exe belongs to this family. Identifying and closing the parent app immediately terminates all its child WebView2 processes and returns that RAM to the pool.
For a broader look at what else might be slowing your machine down, the guide on Windows performance tuning with built-in tools covers several overlooked optimisation methods that cost nothing and take less than 30 minutes.
Should Microsoft Fix This?
The straightforward answer is yes — and the path forward already exists. Windows 11 ships with WinUI 3, a modern native UI framework that Microsoft itself uses for apps like the Settings panel and the revamped File Explorer. Building Weather as a proper WinUI 3 application would eliminate the need for a full Chromium runtime, slash memory usage by 80% or more, and still allow live data from MSN’s weather APIs. The advertising component could be retained via native ad SDKs rather than a full browser rendering engine.
Until that happens, the weather app RAM usage problem is a user-side configuration issue. Microsoft has acknowledged bloat concerns in general but has not committed to a native Weather rewrite on any public roadmap as of mid-2026.
The Bigger Picture: Web Wrappers in Windows 11
The Weather app is the most visible example of a broader trend. Several Windows 11 inbox apps — including the Widgets panel, parts of the Teams Chat integration that shipped in earlier builds, and certain Office companion features — rely on WebView2 rather than native code. Each one spins up its own Chromium renderer, and they don’t always share process resources efficiently.
For users on 8GB machines, this matters enormously. Microsoft’s own minimum RAM requirement for Windows 11 is just 4GB. A single Weather app session consuming 1.2GB represents 30% of the entire minimum-spec RAM budget for one background app delivering weather data you probably also have on your phone. On a 16GB machine the impact is more manageable but still measurable — particularly on devices running multiple productivity applications simultaneously.
If your Windows 11 licence is due for renewal or you’re setting up a new machine, it’s worth knowing that a properly activated, genuine Windows 11 licence starts the OS on the right foot.

Frequently Asked Questions
Is the Windows 11 Weather app a virus or malware?
No. The high memory usage is a legitimate architectural issue, not malware. The Weather app is signed by Microsoft and ships as part of the Windows 11 default installation. Its RAM consumption is a design consequence of using a Chromium-based WebView2 wrapper rather than native code, not a sign of compromise. Running a full malware scan will confirm nothing malicious is present.
Will disabling the Weather app break anything else in Windows 11?
Uninstalling the Weather app removes it from the Start menu and the Widgets panel, but it does not affect Windows Update, system stability, or any other built-in feature. The Widgets panel itself will still function — it simply won’t show a weather card if Weather is uninstalled. You can reinstall the app from the Microsoft Store at any point with no loss of data.
How do I check current weather app RAM usage on my PC?
Press Ctrl + Shift + Esc to open Task Manager, then click the Processes tab and look for Weather or Microsoft Edge WebView2 Runtime. Sort by Memory to see the full picture. You may see multiple WebView2 entries — these are all child processes of the Weather app and should be counted together for an accurate total.
Does the Windows 11 weather app RAM usage get worse over time in a session?
Yes, typically. When the app first opens it loads the initial page, but as you interact — switching forecasts, clicking maps, scrolling through news articles embedded below the weather data — the WebView2 runtime loads additional page resources and caches them in memory. Usage can climb from 1.2GB to 1.6GB or higher in a longer session without the app releasing memory until it is closed.
What’s the best lightweight weather app for Windows 11?
The lowest-RAM option is to use a pinned browser tab pointing to a weather website like weather.gov, since your browser session is already open and no additional Chromium instance is needed. If you prefer a standalone app, community-built native WinUI alternatives from the Microsoft Store typically consume under 150MB. The Windows Search bar also provides real-time weather cards without opening any separate app at all.
