I guess we are all having different experiences at the moment. I have my main test on a very standard i5 laptop. I have not encountered, so far, any "bugs". My feedback , a different matter, has been quite large, but these are concerned with suggestions - mostly ignored, I would imagine -lol.
My inquiries in this, or any other forum, are not intended as rudess, but merely to see a point of view, for possible feedback.
Working through your post, for example.
You find 10 quicker. Is this overall, or in any specific function? I have the two Oss (8.1 and 10) installed on two identical laptops, running side by side. My timing is not sophisticated and only done watching the clock ticking. Iimho, I have not been able to see any difference in speed that I could comment on. As for booting. This could well pivot on how you installed for your dual boot. If you installed Windows 10 after Windows 8.1, then, as has always been the case, the Os installed second, has precedents, and will boot straight through, plus whatever time you have selected for the boot procedure. For the first OS installed, however, after reaching the boot manager, the computer is rebooted into the OS, and that time, however prohibitive, is , or can be, quite a penalty. In my case, I find both Os's pretty well matched. Possibly Windows 10 is a little slower, but I have done very little customization on that.
" do find it easier to find things then in 8, that is partly because I never used 8 with the Metro screen even when I beta tested it."
Not sure how to tackle that. To me, disregarding the Metro screen for the moment, I cannot see any difference? Or perhaps you mean the , now, access to Metro functions?
I agree that it does seem to be compatible with most software. Obviously I am never able to cover that, but All the software, dating back to Windows 7, which I used, I am still able to use through Windows 8 and Windows 10.
My view may be different to yours. As it does appear to perform like Windows 8.1, it is a temptation to use it as a primary OS. However, I would advise strongly against that. MS are undoubtedly going to throw in quite a few updates, between now and the final release, which you may or may not find suitable.
FWIW. I have been prowling through the system folders, to justify a small suspicion in my own mind. With the vast number there, it would be a lifetime feat to look at them all, but, so far, covering about 40, I have found them all identical to Windows 8.1 (??) P.S. That is size only. of course.
But, having said all that BS. I am still supportive of the OS, and am hoping that, in its maturity, it will develop into something quite useful. Of course, bearing in mind the majority of user criticism only concerned the lack of a start menu, that majority has already been satisfied! Another was the interference of the Charms bar - that has also been dealt with
