What is that supposed to mean "register bits"? In memory and registers, there are bits and bigger words, and any non-nonsense programming languages provides a facility to manipulate bits.

The only thing is: you don't write anything in "any" programming language, you always write in a particular one. It's not the same as cross-platform programming where you write one line of code suitable for all supported platform.

Therefore, the question makes little to no sense. Just learn how to do it in each separate language. This is simple enough.

I believe you mean to say "registry", not "register", which is misleading people to think that you want to manipulate the bits of the CPU registers.

Given you say "hkey/local":

1. any compiled language that runs on Windows should have a library that lets you change registry values. This includes the common ones: C, C#, C++
2. most duck-typed languages (like Python, Ruby, etc) will have plugins specific for Windows that will let you change registry values.
3. Other languages, like Go, R, etc., look to see what they provide.

Remember that the registry is a Windows platform-specific thing, so you have to look for what platform specific capability exists as a library, etc., that is accessible to the language you want to use.

Which is the point--it's not the language, but the supporting libraries, that you need to be looking at.

You get whatever the API exposes for the device you're talking about. No, not every web cam, in your example, is going to expose this functionality.

Also, why would you want to turn the LED off when the camera is on? There is only one legitimate reason to do that and I seriously doubt you're going down that path.
