It will remain controversial with the dedicated dislikers, I'm afraid. MS haven't dealt with the most singular (and unnecessary) complaint - the reintroduction of the old start menu on the legacy desktop.
I am at home, and at ease, with windows 8. 8.1 has brought in some new items which, on first examination, I think I have dealt with in other ways. I am a supporter, but I am suspecting that Microsoft, having realised the unpopularity of Windows 8, at an early stage, have subtly leaked out enough information and hints on the forthcoming Windows 8.1 update, to create a final placebo effect on users.
Looking at favourable comments on forums, from early users, it is obvious that, in many instances, those users did not really give Windows 8 a fair trial. They now seem to be content with the "improvements" in 8.1, which, in reality, do nothing for the performance of the OS.
The modifications in the Metro screen really only amount to moving the various functions around a little, that is, apart from the ability to now resize the icons a little more. The smallest size is, in fact, of little use to me as the text title then disappears and, at my age, I find it close to impossible to remember the actual function of all those pretty pictures - lol!
Not sure why they bothered to change "My Computer" to "This PC". But I have had to change it back again on my test Laptop to "Laptop" to distinguish it from my PC !!
