Windows apps these days can be in written in a variety of languages, just depends on what kind of app you are writing – so it could be C#, C++, or HTML/JS. If you’re familiar with the fundamentals of programming, I would recommend diving into Visual Studio and learning your way around as it’s a powerful IDE for people that know how to use it. The Windows apps tutorials are quite easy imo to follow and you get a lot out of the box.
As for finding your place in the tech world, my advice would be to figure out what you like – and get good at it. Unless you’re applying for some kind of architect or manager position or you are starting your own company, many employers want to see that you have a specific trade that you do very well. The exception to this might be if you are going to work for a very small company where people with a range of skillsets are required.
