Metro really not made for PC

To rid it a lot of options there, including "Classic Shell" which is free software under the MIT license and that does the job.

Otherwise, the stability is at the rendezvous, the boot times are decreasing, which is fine, the interface does not seem too resource-intensive, which is good too, there's a lot of small innovations well practice (the Task Manager, File copy interface ...) which you get used very quickly.

Without this horror Metro interface, I would have put a 4, or even 5, but it is so debilitating to see it reappear when you do not expect it that I really can not go further than 3 !
