Yup.

From Microsoft, by now for too long I've seen too much poor quality work, apparently bottom to top in the stack and left to right for the applications. I hate to say this and am betting my startup on Windows as the platform, but for too long there have been too many security problems, poor documentation, bugs, "buffer overflows" still, even design issues (Vista), etc.

Windows 10? That's a lot, from Windows 3.1, NT, ..., 8.1, and now 10, along with Windows Server, etc. -- that's a lot of software that is supposed to be really serious. So, we have to expect that by now Microsoft could get the routine things right for Windows 10 and not ship something that will need 10 service packs, with lots of user struggles with lots of problems along the way, to get to a solid chunk of code.

E.g., the OP looked like just a fast review of 10 but still found some serious problems. So, it looks like Microsoft never did a serious critical review and fixed the obvious issues.

I've seen some good work from Microsoft, but there's also been too much poor work, and some of that seems to be in 10. Not good. Microsoft shipping bad code for their main product is an old story that needed to end a long time ago.

I just want Microsoft to put their game face on, come ready to play, take bugs, errors, etc. seriously, and design and write good code.

E.g., I'm concerned: Clearly Microsoft wants to push their users into Windows 10. Well, if 10 has problems it shouldn't have, then I will have problems I shouldn't have.

At this point, I'm very concerned about the basic quality of Microsoft's work.
