I am using pyinstaller to port my python programs into windows executables so that I can distribute them among my friends, and I recently assigned python to my windows PATH (I'm still not 100% sure what that means so idk if im even saying that right) and now a large amount of my computers basic powershell commands are no longer recognized; trying to use the cmd cmdlet i am only met with the "not recognized as the name of a cmdlet, function, or operable program" error. I've checked the internet pretty extensively and I haven't found anything that works, if you know what's going on or have any ideas on how to fix it, any help would be greatly appreciated. 
P.S. I am an amateur programmer and I just started dipping my toes into python, so I apologize if I don't give enough/correct information, I am still very new to this and am happy to answer questions as needed. Also sorry if this is the wrong place to ask about these kinds of issues, idk where else to ask. (pls be nice im new)
