There will be significant changes in who is permitted to write a program for Windows 10, and tight controls on a special Microsoft-Only signing process required to use a program.
Windows 10 to be released this summer 2015 is said to be a free upgrade from Windows 7 and 8, even if they were pirated.
More interesting is that Microsoft is giving Windows 10 for Pi away free. And expressed a need for a community where there can be more trust. Looks like someone has their act together.
Bad news. Microsoft doesn’t yet have a viable replacement for Windows 7 and they are starting to terminate it. Using Windows 8 is like writing government specs on a cell phone: it might be possible in the same way that technically, I could write all software in machine code only — no compilers — and loaded the code into memory manually using paper tape. No wait: cell phones have that blasted spelling correct/corrupt-er. Make that writing in machine language while a rogue virus randomly changes the codes that I have already written.
