What do I get out of it using double the memory? It has zero new features that a normal human would want. There's supposed to be a benefit in a cost/benefit comparison or you just get a divide by zero error.
See my other comment in this thread for a list of the many, many, many ways Microsoft continues to chose not to improve.
There's a number of new features to the Windows desktop experience, I'm not really interested in reenumerating all of Microsoft's marketing here.
Personally I find the Windows 11 desktop experience far better than 10, despite it possibly using 1% more of my system memory at peak times.
And FWIW, on my Windows 11 desktop explorer.exe is using 110MB, not even 200MB.
