Hello @charles de barros ,
Unfortunately, Windows cannot be installed on a Raspberry PI, running Linux on it is by far the most popular operating system on the RPI.
But do not let that hold you back programming against the GPIO!
As seen in this blog post you can program in C# / .Net and make use of the GPIO because .Net Core can run on Linux too.
Note: the example shows how to use Docker on Azure IoT Edge. A regular .Net application running on the OS directly can do the same.
As an alternative you can use other programming languages like Python. Yes, perhaps there is learning curve but it is always interesting to learn another language.
