No it is not way better when you have elements of Windows 2000 in the menu ui and different functions buried under old sub menus.
Not sure what you're complaining about here. Are you saying that because Windows still has some menu features remaining from the older versions of Windows NT from which all modern Windows versions have descended that the UI is crap? Yet macOS, even with many of the same elements as the original Mac OS X 10.1 still remaining in the UI is somehow different?
Why does each release continue to be more bloated than the last needing more and more resources in order to perform when the opposite should happen at least to a degree. Making software more efficient and ending some legacy compatibility would probably go a long way.
Windows hasn't become significantly more processor or RAM intensive since the Windows 8 days (in fact, even Windows 8 tended to perform better than Windows 7). Windows 8 through 11 have all run pretty much the same on similar hardware. That's why there is so much uproar about Microsoft ending support for 8+ year-old hardware - there are literally
millions of 10+ year old Windows computers technically able to run Windows 11 perfectly fine except for Microsoft's artificial hardware support limitations.
Improving the base kernel
How? What about the base kernel do you think needs significant improvement?
Same question.
uniting all of the menus and modernizing their UIs.
Well, as far as "modernizing UIs" go, it seems like at least since the release of Windows 10 and the modern "flat" UI, it has been Microsoft creating modern desktop UIs and macOS and Linux environments following their lead. Other than apparently trying to re-invent the Windows Vista / Mac OS X 10.4 experience with Liquid Glass in the current beta cycle, Apple certainly hasn't really done much on the "modernization" of UIs in nearly 15 years.
Uniting the menus in Windows I certainly can agree with, but I think progress is still steadily happening in that area in Windows. At this stage, the places that are still using "legacy" UI elements (ie, Device Management, some utilities, certain settings still buried in Control Panel, Group Policy and other Admin tools) are things that generally still work very well and are very seldom used by end-users.
Unless you're talking about the menu design in applications themselves, in which case that will never happen because Windows doesn't (and never will, hopefully) have the "menu perpetually at the top of the screen" design that macOS has and application developers are free to design their menus however they see fit.
Figuring out how to make the OS easier to use with less clicks per task or action instead of doing the opposite.
You mean like closing an application? Or switching between virtual desktops? Or arranging multiple application windows on large screens? Or having dynamic contextual menus to complete common tasks? Because right now Windows has macOS and Linux beat in all those aspects, and that doesn't seem like it is likely to change any time soon.
As an example that is purely observational. My Windows laptop with top of the line Intel processor, lots of ram and ssd. Really overpowered but efficient. Yet if I just turn on and log into my account on Windows and do nothing the processor is running doing a lot of work doing nothing. So what is it doing? My opinion is Telemetry is constantly working the OS in the background.
Really doubt it is telemetry. Telemetry doesn't take nearly enough bandwidth to cause that kind of a slowdown and if it were the cause, it would be constant, not just when you first log in. In my experience it has been either bloatware from the hardware vendor (Dell is bad for this, their management tools are pretty awful - I run into this same issue on my work laptop and it doesn't affect any of my other older laptops), or it is sometimes Windows update (generally if you haven't used your laptop in a while). Couple this with the fact that Intel mobile processors are just garbage these days, and it is easy to see how this can happen on a Windows laptop.
My MacBook doesn't have any such issues. A M2 MBA that is fanless seems to be as fast or faster than newer Windows laptops and runs longer, cooler, and doesn't have some invisible payload going on in the background.
This is one of the few areas that Apple absolutely blows away everything else - the M series processors are a massive performance improvement over x86 on mobile devices and it is not even close.
I remember the days of XP, Windows 2000, Windows 7 which were some of the best Windows releases all of which were paid releases. They were terrible at security which has greatly improved but they were very efficient OS.
Windows XP (and to a lesser extent, Windows 2000) were most PC users' first introduction to a modern operating system ("modern" in this sense meaning fully 32-bit with protected memory, multi-threading, pre-emptive multitasking, and real multi-user security). Compared to the world they were coming from (either DOS-based Windows or Classic Mac OS) the reliability and responsiveness of using XP or 2000 was a massive improvement. I think this experience is why many people tend to view that era with a particularly rosy set of glasses. Windows 7 also has some of this (though to a lesser extent) partly because of the terrible experience that was Windows Vista and Windows 8.
From a security, UI, and stability perspective, Windows 10 is a far better operating system than any version of Windows that came before it and Windows 11 has some improvements over Win 10 (though also some back-steps, such as the relatively ****** Start menu and Task bar).
I wish MS would return more to it's roots. Be the hobbyists computer with modularity at the hardware level.
You want Microsoft to go back to making BASIC interpreters for 1970's microcomputers? Because they haven't been "the hobbyists computer" since long before the haydays of Lotus 1-2-3 and WordPerfect.
