The only Windows Internals course you need!
Pavel doesn’t need an introduction! I’m currently taking his Windows Internals Master course, and I’m learning heaps in every single lecture. This course is thoughtfully designed, well-structured, and clearly delivered. I’ve already made up my mind to take another one of his courses, Windows Master Developer. I highly recommend Pavel and TrainSec to anyone who wants to level up their skills. Also, great customer support. Mikey responded quickly to all my queries and was super helpful.
