And they're all fixed. That's pretty cool.

because handling the UI in kernel space gives you performance.

There is a reason it's done that way.

>gee, there totally isn't a conflict of interest in researchers at Google trying to find security vulnerabilities in a competing product!

nearly everything is being done in kernlel space on windows

why do you think windows 10 still looks like 95 at some places?

Kernel space - drivers, interrupts, core system to interact with hardware
user space - windows, google chrome, control panel etc...

No, you fucking idiot, look at the fucking OP image to see my reaction and read the fucking OP text. Fucking understand that wangblows is a piece of crap because too much is being handled in kernel space, even the window chromes. One single buffer overflow in the UI can give control over the whole OS with very little effort.
