I must say it's growing on me.
I've managed to get rid of those two icons (the search and that silly notifications) which means my bar is nicely empty again (except for the OneDrive icon in the System tray and my two pinned applications: Firefox and Explorer.
I have some colours back on my title bars of my windows.
I do like the very angular layout of those windows
Now I need to get rid of that huge part of my start menu... I don't have any tiles in there, nor do I want them in there, but it still shows that huge block...
Found out I can just resize that start menu
Edit:
Ok, that start menu is still an issue, you cannot add applications on the left side of it, only on that annoying big thing on the right... I don't care for those tiles, I want a simple small icon list on the left side!
