Win32 API and Migrating to C++ from C

I was not sure where to put this so I am sorry, this is a Windows 10 / Windows 11 development question. So I recently learned C (I have been programming in 13 other languages for 12 years), and was nervous about attempting C++ even though I know it was meant to be an improvement upon C because it adds a lot of things like OOP. Would it be a hard leap for me to make that jump? Also, for the Win32 API, is it possible to only code in C if you are working with low-level processes mainly when using it? 

Thank you,
I am an aspiring Windows 10 and Windows 11 Developer, I migrated from Linux development 2 years ago and have an extensive background in systems development and machine learning. That's why I thought I would ask the question here because I am using the Win32 API for Windows 10 & 11 development. I originally learned Rust, Zig, and D as I was trying to do everything I could to avoid C/C++, to the point I even learned x86 NASM first lol.

Take care.
