Re: why GUI part of the kernel

GUI (graphical user interface) is NOT part of kernel.

GDI (graphical device interface) is implemented in kernel, for performance
reasons.

Heya,

I read that the GUI in windows XP (NT) is part of the kernel and this
for speed up reason.
I can't see how this decision will speed up the execution as every
interaction requires now a mode switch. whereas if it was in user
space, this overhed is avoided

any help please

many thanks
