UC – Windows Internals

If the operating system is the middleman between programs and hardware, then learning Windows Internals is how you figure out what that middleman is really doing. It’s the study of how Windows launches programs, assigns memory, handles files, and manages privileges behind the scenes. It’s not about the buttons you click; it’s about what actually happens after you do.

This free Upskill Challenge puts a widely used operating system on the operating table and places the scalpel in your hand. Shikata takes you on a guided tour of what Windows Internals are, what they consist of, and the security implications that every budding security engineer should know.

Price = FREE!

What’s an Upskill Challenge (UC)?

A UC is a CTF-style, bite-sized lesson from the JHT Team, our courseware developers as well as “friends” of JHT. They are meant to be short and to the point. UCs focus on a single tool or concept and are helpful in quickly providing useful skills that might be prerequisites for other types of educational content on the platform.

A UC should be 10 – 30 minutes of student time and have no VMs. There are quizzes to make sure that the content is understood.

Prerequisites for “UC – Windows Internals”

UCs assume no knowledge at all! They’re meant to be completely self-contained, so all of the answers are in the lesson. No outside research is required.
