If anyone has a blurry device manager in Windows 10 set your screen back to 100% instead of 125%.
There's a visual glitch that makes a few windows like device manager look weird if you use 125% scaling for your desktop.
The option is under "customize your display". Make sure it's 100 for now. I'm sure there'll be a fix later.
Other than that I haven't noticed any trouble with Windows 10 (and yeah it does try to make Edge the default if you do "express install").
I never do express install for anything. My mouse automatically migrates to custom.
