How difficult will it be to write your own driver for win10?

Question

Windows

Good afternoon. Is it difficult to write a driver on win10?
Just now I'm doing a lot of drivers, namely reinstalling Windows. And sometimes you don’t find the right driver. Of course, this is extremely rare. Still, I'm interested in how long it will take to write a driver, for example, for a processor. Well, and how difficult it is. I'm not a programmer, I don't do much web development. So please explain as clearly as possible.
Thanks in advance everyone

Answer 1

In your particular case, it's very difficult.

Answer 2

From a case of beer - if there is a good qualified programmer.
Up to five lemons rubles if you need a certified driver.
