>>7021706>Customizing what exactly?
Have you ever tried running a different window manager on Windows?
Can you even get a decent tiling window manager?
I get that you can get a lot of things done with rainmeter, but when it comes to window manipulation and customization you are limited due to the nature of windows.
Also an important point is that every component in a Linux system is replaceable.
On windows it is practically impossible to replace the default desktop entirely with other software all you can do is cover it up.
