How to Determine where to install hidapi.dll?

问题

Context: A Windows 10 attempt to install and test python hid per instructions:

 pip install hid

The test to import the module failed:

Released hidapi-win.zip includes pre-compiled:

   hidapi.dll
   hidapi.lib

Question: What is the thought process & facts necessary to determine the proper location to install the two files? Assume a recent new install of Windows 10 and Python 3.8

Paste the .dll and .lib file inside the Windows/System32 folder. After that restart the terminal and the hid module should find the library without a problem
