Getting all of this to work on Windows seems like a bit of a thankless task. If customisability is important, why wouldn't you just go over to Linux?
It’s less work on Windows for many things, and the system of UI events, hooks, and controls is more amenable to universal customization/automation than on Linux, which is more heterogeneous between applications, window managers and desktop environments.

As a windows power user myself, many of my workflows don't translate that easily. If you are an experienced Windows user, you probably have programs that you use on Windows and that aren't available for Linux. It's not that you couldn't theoretically translate that workflow into Linux, but boy, it would be a headache.
To give an example: I use AutoHotkey, it's a scripting language for Windows that allows you to do a bunch of things. You can customize the keyboard, mouse, you can create menus and toolboxes, you can target specific applications inside. It's a fantastic tool. But it isn't available for Linux for obvious reasons; Linux is much more fragmented. You need like 3 or 5 different programs to achieve the same result in some cases, depending on your given script.
In other words: debloating Windows and customizing it is considerably easier than installing Linux. Let alone some really good software you end up finding along the way: Everything, which is an amazing search program that allows you to create custom categories and the like. EmEditor, which is really good software to open and visualize really large text files, like it can open a 4GB txt with no problems.
About the last sentence:
>If customisability is important
People value both things: customisability but also they value their time (of not having to come up with a new workflow), they value the programs and workflow they already learned to use through the years, and so on and so forth.
