Answer 1

Is it possible to program under Windows like in DOS using functions and interrupts?

Depends on which interrupts you have in mind. If dosovsky int 21h - then Windows has its own API , if you mean "handle interrupts yourself" - then you need a kernel driver.
Functions can be used in general everywhere.

Answer 2

To do this, you need to write a kernel-mode driver.
