From the swedish article shared above:
"One thought has begun to creep in - what if Microsoft decided to switch the NT kernel in Windows 10 to the Linux kernel? Could it be possible that Windows 11 (given the naming convention) will build on Linux?
Given that the graphical interface would continue to look much like it does today, users would hardly notice any difference, except that it is not entirely insignificant that the operating system should be perceived as both faster and, above all, more stable. Now Windows 10 is considerably more stable than older versions, but relative to Linux it is still a bit left.
Another not entirely unimportant advantage would be that the security of the operating system would probably increase by a magnitude or two. Again, Windows 10 is good, light years better than older versions, but firstly, most threats to Windows develop - simply because it is the biggest - and secondly, it would mean that many of the criminal hackers would have to retrain , and they would definitely have a harder nut to crack.
The NT kernel in Windows seems to have deep structural problems. This is not least noticeable in connection with these constantly updating updates. For us in IT media, it’s a cornucopia; It is grateful news to write about and it is popular with readers, but it may not be very fun for Microsoft to constantly have to back up updates, bug fixes create new bugs, and have to take the criticism it rightfully gives rise to. To top it all, it has to be very expensive.
Microsoft also does not want you to run Windows on a classic local PC; Microsoft would prefer you to run virtual desktops on Azure along with cloud applications such as Office 365. A strong contributing factor to this is the endless myriad of different hardware variants that the operating system must support, which is probably the most important reason for the updates not working as they should.
Microsoft also stands for perhaps the most unexpected and radical change in IT history - who could think of Steve Ballmer’s time that Microsoft would start not only accept Linux, but really like Linux. Current CEO Satya Nadella’s now classic “Microsoft loves Linux” seems to be true and honest in every way.
That Nadella is serious is not least noticeable in practice. By far the most common operating system on Azure is Linux, Microsoft has released upwards of 50,000 patents free, they have bought and integrated with Github (hello, we are talking Github!) And Microsoft is contributing a lot of open source and supporting a plethora of open source projects. Microsoft is even contributing to the Linux kernel, though the contribution is small compared to Red Hats, Intel, IBMs and others. But in general, Microsoft is contributing, by itself or through support to others, with lots of open source.
If Windows 11 switched to Linux, Microsoft would not have to be entirely responsible for the development and maintenance of the core of Windows, and take the entire cost, but of course contribute more to the development, for purely selfish reasons unless otherwise.
But wait, it’s not possible to run Windows applications on Linux. True. Or not, it depends. Crossover and Wine are two long-standing emulators, and they seem to work reasonably well, but not well enough. On the other hand, it should not be forgotten that the developers of Wine and Crossover do not have access to all the monkeys and system calls that of course the developers of Microsoft have. An emulator developed with full access to the code would work much better. Microsoft would probably develop a virtual machine on which Windows applications could work just as before, but at the same time do everything they can to port applications as quickly as possible.
In fact, Microsoft has already started moving this way with the Windows Subsystem for Linux, WSL (now WSL 2). With WSL, Microsoft has started to build a system where they map Linux api and system calls to Windows, and vice versa. The first version of WSL meant that Microsoft linked Windows built-in libraries and programs with Linux, and with WSL 2, Microsoft has taken the step fully and created its own, customized Linux kernel. Thus, Windows already comes with its own Linux kernel which, it seems, works as a glove with Windows.
So, really, what would be the next step? Well, to build Windows on Linux. I put my 10 cents on it."
Another great thing about apple.
