I'm glad I'm not the only one who thinks this - I keep finding bits in W10 which seem like a student's half-finished project - the print dialog in Edge's PDF reader was the latest mess I found after a recent update. I detest the UI, it's horribly unfriendly (to my eyes, anyway), and the fact that when I keyword search for an app I use every day (Notepad++) I usually get Notepad as a suggestion before it shows there's something wrong, to me.

I guess part of the problem is that Windows 7 had reached the same plateau as Word had - it does everything most people need and there's no real reason to upgrade, and that MS wants to grab a part of the app/user data market so has tried to shoehorn all that into the mess left by the "windows will be the new IOS" debacle that was Windows 8.
