Hey everyone! I'm currently working as a sysadmin and I've been creating some automation tools in Python, primarily using Flask for web interfaces and more recently PySide6 for desktop apps. Now, I'm looking to step it up and build some powerful Windows utilities, similar to tools from NirSoft or RegShot, that require deeper access to the operating system than Python typically provides.
With that in mind, I'm trying to decide which programming language I should focus on: C, C++, or C#. Here are a few things I'm considering:
- I want to keep development time reasonable and maintain good productivity; I'm not looking to rewrite Windows, just create solid, maintainable admin tools.
- I need access to Windows internals and APIs, including the registry, services, NT APIs, ETW/WMI, and file system hooks.
- Stability and robustness are crucial; I want to avoid crashes for users.
- Packaging and shipping my applications for Windows users should be straightforward.
- Lastly, it would be great if I could maintain some interoperability with my existing Python code.
Considering all this, I'd love to hear your thoughts: Which language would you recommend for building Windows admin tools, and why? I'm interested in any real-world pros and cons you've encountered regarding stability, development speed, and packaging. Also, if you have any tips on libraries or frameworks that can help with low-level Windows work in these languages, or advice for Python interoperability, that would be super helpful. Thanks in advance for any tips, examples, or resources you can share!

If you like object-oriented programming, I'd suggest C++. It's not only capable of low-level operations but also lets you manage complexities more elegantly. On the other hand, if you're not into OOP, then C could be a suitable option for you.
If you're dealing with low-level Windows APIs, C++ is usually the way to go, especially with modern C++ standards like C++17 that enhance robustness. While C# provides access to a lot of APIs, when you need direct interaction with Win32 or related driver tools, you may find its capabilities limited.
Integrating Python with C or C++ can be fairly straightforward. You can use ctypes for embedding or just have your Python scripts call an external executable for the heavy lifting which often simplifies things.
C# is definitely a strong candidate. However, the challenge comes from choosing the right GUI framework since Microsoft tends to deprecate them quickly. C and C++ might be more challenging with stability when starting out due to their complexity, and I think they’re more suited for high-performance needs rather than user-friendly GUIs.

Modern C++ really broadens the discussion on OOP—it's not the only way to program, and using it exclusively can actually lead to poor design. If you or your team are strongly set on OOP, then C# might be a better fit.
