System Path question: Windows is extremely organized (as you know already) in order for it to follow a logical, orderly method in accessing, executing and running various programs. Otherwise it would not function on every computer, nor would 3rd party programs run or even be installed. The system path your Python error message refers to is the directory, sub-directory and system file where that Pip file is supposed to be in, but it is not there. I know nothing about Python, but I suggest reinstalling it.
The Program files (x86) directory is where all 32 bit programs (and many 64 bit programs) are installed to. If you scroll down that directory you will find the names of the majority of installed programs on your computer (not including Windows-that has a separate directory all its own further down Explore). The Program Files directory just above the x86 directory is where most of the 64 bit programs are installed to, but not necessarily all of them. I have found 64 bit programs also installed in the x86 directory.
To start answering all questions about Windows would take far more time and space than this forum is intended for. Here is a link to a site that has many aspects of Windows in it. The internet, including Youtube, is loaded with Windows tutorials. Just search "Windows tutorial" and you will have dozens of options offered.
