Re: New Edge, now with even more spyware
And exactly that is what happening with Win10. There is a list of programs/apps (uwp) you used recently. When you minimize it, it is being ‘snapshotted’ in the state it was in and kept in a hybernate state. Thus it can open your window ‘instantly’, because it wakes is from the hibernation state.
And yes, it does this with calc.exe too, because all executed programs are treated in the same way. Now, that you don’t care if calc.exe is kept in memory/hybernation, doesn’t mean that the mechanism is wrong. It treats your calc.exe with the same importance as ‘photoshop.exe’ or ‘illustrator.exe’. Yes, more RAM equals better performance this way. On the other hand, who doesn’t have 4-8GB RAM in their work desktop? And 8-16GB in your private PC probably.
Less RAM means less programs that are kept in hybernation (it saves the state to disk and closes the program where possible).
Now to get more on topic with your comment; You seem to use iDevices with iOS. You might even use an Android device as well. Those OS-es do exactly the same. Granted, you mentioned that mobile OS-es do this, but why should a desktop OS not do the same?
