alt Hacker NewsPutting aside the fact that it is horribly bloated. Accurately measuring RAM usage is tricky, there are several measurements, and no "right" one.
It is clear from the article that what eats up so much RAM is not the weather app itself but the framework it runs on. There is a "Renderer", a "GPU Process",... eating most of it.
The thing that the task manager doesn't tell you is whether or not these are shared components. It may be that the 662 MB used by the "Renderer" is shared between many Windows components, so killing that Weather app may not reclaim as much space as you may hope, instead, it would require killing every user of the component, some may be core system apps.
In addition to the distinction between private and shared memory, there is also the distinction between actual RAM usage and and virtual memory. It is possible for a process to memory map a 100 GB file. If you look at the address space, it will take 100 GB more of virtual memory, even though it may be actually zero physical RAM, but it is not always zero either, the parts of the file that are currently accessed take up some space, which may later be reclaimed by the OS by committing the page to disk.
Even the most obvious "I do a big malloc()" kind of memory use is not that obvious, the OS can overcommit, put stuff into swap, use memory compression, etc... And it can do that even if the system is not overloaded, as to make more space for the disk cache for instance.
So seeing "1 GB" in the task manager is just a vague hint of how it may affect performance. And not all "task manager" tools give the same value for the same program (so Windows vs Mac may be misleading). "Process Explorer", a more advanced version of the Windows task manager can give a lot more details, with different values of memory usage depending on what you are looking at.

From the screenshot in the article, this is the memory usage of the Renderer process spawned by the Weather App. I find it very unlikely that some other app (say, the Copilot app) can then piggyback on Weather Renderer process. Do you have a source for this?
> killing that Weather app may not reclaim as much space
Closing the weather app on my PC does in fact kill all child processes and frees up around 1GB of committed RAM. Are you not seeing the same?
Separate Renderer and GPU Process is just typical webview2/electron
The weather app itself and the framework it runs on are the same thing when talking about resource usage.

You say tomato we say tomahto
At the end of the day bloated app is a bloated app its consequences are the same.

Fine, shutdown the weather and stock ticker apps.

It is the other way around, shared memory causes Task Manager to _underestimate_ memory usage. Task Manager's default views report the process private working set, no shared memory included. This means that 662MB is the _minimum_ amount of memory commit that would be released by ending the process.
> the OS can overcommit
Windows does not allow overcommit by default. It may compress or optimize memory allocations to reduce the physical working set, but the kernel will start failing memory allocations once physical + swap is exhausted regardless.
