Powershell Doesn't Let Me Make Changes in Settings

Question

I was trying to manipulate the windows settings using the powershell. Below is the python code with which I try using powershell-commands to disable the taskbar (the automatically hide/show setting in this case) programatically.

import subprocess

def change_taskbar_visibility():
    powershell_commands = [
        '$regKeyPath = "HKCU:\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\StuckRects3"',
        '$regValueName = "Settings"',
        '$currentSettings = Get-ItemProperty -Path $regKeyPath -Name $regValueName',
        '$currentSettings.Settings[8] = 2',
        'Set-ItemProperty -Path $regKeyPath -Name $regValueName -Value $currentSettings.Settings',
        'Stop-Process -Name explorer -Force'
    ]

    cmd = ";".join(powershell_commands)

    subprocess.run(["powershell", "-Command", cmd], shell=True)

if __name__ == "__main__":
    change_taskbar_visibility()

However the taskbar only hides for a couple of seconds until it reappears again, so the changes I've made didn't stay. Do I have to modify my code to make it work or is there somethin in the os I need to change?
