Is there anyway of programming Excel to interact with functions of Windows
that are independant to Excel?

For example the volume control or printer monitor (or any other things in
the task bar and/or start menu)?

Yes, you have to find and declare the Windows API function that does what
you want. In VBa, this is done pretty much like VB6
Here are a two links that I found:
