[Python] How to list all app/software/programs installed on Windows 11 using a Python script

I develop a Python script to list all installed apps in my Windows 11 system. I would like to replicate the same results displayed in Settings > App > Installed Apps. Optionally, I would like to list apps installed not only for my user but in the entire system. Surfing the web, I found these four commands:

cmd1 = "Get-WmiObject -Class Win32_Product | Select-Object Name, Version, Architecture | Sort-Object Name"

cmd2 = "Get-AppxPackage | Select-Object Name, Version, Architecture | Sort-Object Name"

path = f"HKLM:\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\*"
cmd3 = f"Get-ItemProperty -Path {path} | Select-Object DisplayName, DisplayVersion, Architecture | Sort-Object Name"

path = f"HKLM:\\Software\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\*"
cmd4 = f"Get-ItemProperty -Path {path} | Select-Object DisplayName, DisplayVersion, Architecture | Sort-Object Name"


I develop a simple code to run these four commands sequentially:

def list_installed_apps(cmd: str):
# Run the PowerShell command and capture output
result = subprocess.run(["powershell", "-Command", cmd], capture_output=True, text=True)
# Split the result into lines and filter out unwanted lines
installed_apps = result.stdout.splitlines()
return installed_apps

cmd = "Get-WmiObject -Class Win32_Product | Select-Object Name, Version, Architecture | Sort-Object Name"
apps_1 = list_installed_apps(cmd)

# Find the index of the header line and column label boundaries
header_index = [i for i, app in enumerate(apps_1) if app.find("Version") != -1][0]
header = apps_1[header_index]
bound_1 = header.find("Version")
bound_2 = header.find("Architecture")

# Remove the header and any empty lines
apps_1 = [app.strip() for app in apps_1 if app.strip() and "Name" not in app]
apps_1 = apps_1[1:] #removes the line of -------

apps_1_ordered = [
{"name": app[:bound_1], "version": app[bound_1:bound_2], "architecture": app[bound_2:]}
for app in apps_1
]

header = apps_2[header_index]
bound_1 = header.find("Version")
bound_2 = header.find("Architecture")

# Remove the header and any empty lines
apps_2 = [app.strip() for app in apps_2 if app.strip() and "Name" not in app]
apps_2 = apps_2[1:] #removes the line of -------

apps_2_ordered = [
{"name": app[:bound_1], "version": app[bound_1:bound_2], "architecture": app[bound_2:]}
for app in apps_2

path = f"HKLM:\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\*"
cmd = f"Get-ItemProperty -Path {path} | Select-Object DisplayName, DisplayVersion, Architecture | Sort-Object Name"
apps_3 = list_installed_apps(cmd)

# Find the index of the header line and column label boundaries
header_index = [i for i, app in enumerate(apps_3) if app.find("DisplayVersion") != -1][0]

# Remove the header and any empty lines
apps_3 = [app.strip() for app in apps_3 if app.strip() and "DisplayName" not in app]
apps_3 = apps_3[1:] #removes the line of -------

apps_3_ordered = [

for app in apps_3
]

path = f"HKLM:\\Software\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\*"
cmd = f"Get-ItemProperty -Path {path} | Select-Object DisplayName, DisplayVersion, Architecture | Sort-Object Name"
apps_4 = list_installed_apps(cmd)

# Find the index of the header line and column label boundaries
header = apps_4[1]
bound_1 = header.find("DisplayVersion")
bound_2 = header.find("Architecture")

# Remove the header and any empty lines
apps_4 = [app.strip() for app in apps_4 if app.strip() and "DisplayName" not in app]
apps_4 = apps_4[1:] #removes the line of -------

apps_4_ordered = [
{"name": app[:bound_1], "version": app[bound_1:bound_2], "architecture": app[bound_2:]}
for app in apps_4
]


##############################
# SUM RESULTS OF ALL COMMANDS AND SAVE
##############################
all_apps = apps_1_ordered + apps_2_ordered + apps_3_ordered + apps_4_ordered
fileName = "" # SET YOUR NAME
with open(fileName, "w") as f:
for app in all_apps:
f.write(f"{app['name']} --- {app['version']} --- {app['architecture']}\n")


Unfortunately, this file content doesn't completely match the apps sorted in the settings. How can I obtain that list?
