windows - pip will not update, install completes successfully but version never changes

I was tired of seeing the warning so figured I'd update pip from 21.0.1 to 21.1.2, however, when using the command D:\Python38\python.exe -m pip install --upgrade pip, or python -m pip install --upgrade pip, the version never changes to 21.1.2. I have restarted my terminal, I have checked my path, the only thing I can think is that I changed the global.cache dir to my D: drive to conserve space on my windows hog of a machine. Here is a snippet from my terminal of what I have going on.

D:\>python -V

I have scoured the internet for an inkling into why this is happening but I can't seem to find an answer. Thing is, this isn't something that I have to have done, it's just nagging at me that I cant figure it out at this point.

I have read through the pip documentation config file and user guide and of course I have looked for my answer here before asking my question, I hope someone out there can give me some insight and thank you for your time.
