From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It isn’t as simple as just compiling. Large programs like games then need to be tested to make sure the code doesn’t have bugs on ARM. Developers often use assembly to optimize performance, so those portions would need to be rewritten as well. And Apple has been the only large install of performant ARM consumer hardware on anything laptop or desktop windows. So, there hasn’t been a strong install base to even encourage many developers to port their stuff to windows on ARM.
Yeah this has been our (well, my) statement on requests to put out ARM binaries for Pulsar. Typically we only put binaries out for systems we actually have within the team so we can test on real hardware and replicate issues. I would be hesitant to put out Windows ARM builds when, as far as I know, we don't have such a device. If there was a sudden clamouring for it then we could maybe purchase a device out of the funds pot.
The reason I was asking more about if it was to do with developer licences is that we have already dealt with differences between x86 and ARM macOS builds because the former seems to happily run unsigned apps after a few clicks, where the latter makes you run commands in the terminal - not a great user experience.
That is why I was wondering if the ARM builds for Windows required signing else they would just refuse to install on consumer ARM systems at all. The reason we don't sign at the moment is just because of the exorbitant cost of the certificates - something we would have to re-evaluate if signing became a requirement.
