Some of the criticism is just plain wrong, like the "install software for USB booting install media." Yeah, I can write quite a bit too, about how hard it is to use the operating system, when I'm the one who randomly downloads crapware and tries to install it, instead of just doing a search and using the build in commands to make a bootable usb stick.
Then the whole thing about how the disk manager looked? I mean really? I'm a sysadmin and I probably stare at that UI likely more than any of you here (even when I have 90% of repeating work scripted with diskpart - do you notice the difference in usage scenarios here?) and it never even occurred to me there was something wrong with it? What do you want, a couple of flowers along the edges or something?
