This is my concept of an ideal OS user interface set up to serve the user and not the provider. I call it The Void but it would be delivered with a default UI similar to Windows 10 for the sake of familiarity with most users who just want to click and go. More knowledgeable users could quickly reconfigure the UI how they want it, and this is what they'd get when they do so:
No desktop. The concept of a desktop as a launchpad was always a bad idea. Let me illustrate with a short story.
A factory owner grew tired of chasing assistants to carry out tasks so he called in a few workmen from the factory floor to build him a new desk with loads of buttons on top. One button would summon his secretary, another his vice-president, and so on. They made and installed his new desk but once it was cluttered with his in-tray and out-tray, his blotting pad, keyboard, monitor, desk tidy, and so on, he had trouble getting at the buttons. He had his workmen bring up a couple of the bots from the factory so now when he wanted to find a button on his desk he first pressed a button on the side of his desk and the bot arms swung into action to move the clutter away to a side table - restoring the clutter afterwards.
You see how foolish the above notion would be. But that's what we have with Windows.
The Void begins with a swirling black cloud of nothing. It's not a desktop but a creation space. You can right click it anywhere and a menu lets you create any pane (panel, rectangle, window, box - choose the word you prefer but they are the same thing) or choose defaults. A pane is just a blank rectangle but you can right click it and configure it to be a menu or button holder or a mixture. Each item in a pane is simply a link to an app, a doc, a service, whatever. There are defaults so you might add all installed apps to a menu in one go but also remove or hide what you don't and add individual stuff if you want. You can configure the pane and everything in it to be any colour, any font, any size, any type, any transparency any border, any anything - you design the style - either to your preferred defaults or individually. When I say 'any' I really mean 'ANY' - not a range defined by someone else. You can resize or move any pane anywhere and optionally dock it with any other pane on any side. You can lock it or make it hide and appear - you set all the rules how it would do that. EVERYTHING is optional. Anything you object to can be fixed. Too much like hard work? Right click the void, select say, 'defaults - similar to - Win 7' and you're good to go, plus you can tweak it any which way.
All help is at the relevant point of use by right clicking. You won't normally have to use a separate search or scour the internet like now. Example: a couple of days ago I wanted to change a drive letter. I knew it had to be done through Disk Management but couldn't remember the route to it. I entered Disk Management in the Win 10 search. It suggested formatting partitions (which was the correct route to the task but not very helpful if you didn't already know) or search the web. A more useful OS would link to anything drive-related by right clicking the drive in a file manager where you'd naturally first look.
Most commonly there might be six main panes: a full screen picture as background, a service menu launcher, a start menu launcher, a running tasks manager, a task launcher, and a system tray - but there's is nothing special about each pane because you decide what goes where. If you like desktop icons then you could make the picture pane sit always at the back and permit it to accept shortcuts just like a conventional desktop. Or you can just use the task launcher pane.
The user is never restricted to some style or plan enforced by the provider. Not mass surveillance. Not bloatware pre-installed. Not updates. Not Users. Not logins. Not invisible passwords. YOU choose. You want multiple users? Fine, you add that property. Keep passwords visible? YOU decide to include what you love and exclude what you hate. Why should M$oft decide for you? Then change the style in each successive Windows or update? A default is fine, but give us freedom over everything.
Help can always be reached by right clicking at the point of use. Ultimately leading as a last resort to every conceivable keyword that might enter your head so you can find what you want. People now think it's normal to spend hours doing searches for the simplest task. I say, right click and follow the bread crumbs and virtually always find the info you need in 20 seconds or less. It IS possible! It needs resources, imagination, intelligence, creativity, integrity, and a desire to serve instead of making your customers serve you. Clearly M$oft don't have any of those qualities except the first: DOLLARS, but they're keeping those.
