How to get computer username using Python

1. The getpass module that comes with Python can be used to obtain the password entered by the user, but it can also be used to obtain the computer user name.

import getpass

user = getpass.getuser()
print("计算机用户名为：", user)

2. Use the os module to obtain the user name
Python's os module provides many methods for obtaining system information, including methods for obtaining computer user names.

import os

user = os.environ.get('USERNAME') # Windows 系统
# user = os.getlogin() # Unix/Linux 系统

print("计算机用户名为：", user)

3. Use the psutil module to obtain the user name
psutil is a cross-platform system information library in Python, which can obtain system information, process information, etc., and can also be used to obtain computer user names.

import psutil

user = psutil.users()[0][0]

print("计算机用户名为：", user)

4. Use the socket module to obtain the user name
In addition to the above three methods, the socket module of Python can also obtain the computer user name.

import socket

user = socket.gethostname()

print("计算机用户名为：", user)

Get startup folder path

startup_path = fr'C:\Users\{getpass.getuser()}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup'
print(os.listdir(startup_path))

Windows adds self-starting files

import winreg
def add_to_startup(file_path):    # 要启动的文件入口绝对路径
	key = winreg.HKEY_CURRENT_USER
	key_value = "Software\Microsoft\Windows\CurrentVersion\Run"
	with winreg.OpenKey(key, key_value, 0, winreg.KEY_WRITE) as key:
	winreg.SetValueEx(key, "my_python_script", 0, winreg.REG_SZ, file_path)
	# winreg.DeleteValue(key, "my_python_scrip")  # 清除
	winreg.CloseKey(key)

# path = r'SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run'
# key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, path, 0, winreg.KEY_WRITE)
# winreg.SetValueEx(key, 'MyProgram', 0, winreg.REG_SZ, file)
# # winreg.DeleteValue(key, 'MyProgram')
# key.Close()

Go through the startup folder to add

import getpass
from win32com.client import Dispatch

def create_systemc_start(lnk_name, exe_abs_path):
    '''
    :param lnk_name: 快捷方式名称
    :param exe_abs_path:  要创建的exe绝对路径
    :return: 
    '''
    
    startup_path = fr'C:\Users\{getpass.getuser()}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup'
    start_list = os.listdir(startup_path)

    if lnk_name not in start_list:
        shell = Dispatch('WScript.Shell')
        shortcut = shell.CreateShortCut(os.path.join(startup_path, lnk_name))
        shortcut.Targetpath = exe_abs_path
        shortcut.save()

Manually set the file to start automatically

1. Win + R to open and run, enter: shell:startup and copy the program file or shortcut to be started automatically to the opened window. This method is to open the Start Menu - Programs - Startup folder.

3. Win + R to open and run, enter: gpedit.msc to enter the local policy group, double-click to start in Computer Configuration - Windows Settings - Script (Startup/Shutdown), and add the corresponding script. Need to write bat script first, need to be able to write script code

First write a bat script to execute your exe file: (create a new notepad, copy the following code, save, modify the suffix to bat)

  @echo off
    start exe路径

5. Win + R to open and run, enter: cmd, use the cmd command to add the program to the system service, and turn it on automatically

Add service command:

 sc create 服务名称 binPath= 路径 start= auto

After the addition is successful, you can view the management in the system service management
Note: There is a space after the '=' in the command

Windows cmd command to create system service

sc  create 命令创建一个服务（增加到注册表中）

Double-click to run directly.
As follows: Execute in command line mode:

sc create TestService binpath= "c:/in estapp.exe" displayname= "TestService" depend= Tcpip start= auto

Note: The format here,
note:
1) There must be a space after .binPath=, otherwise an error will occur.
2). If the build is wrong or needs to be modified, you need to delete the service first, and then recreate it. The command to delete the service:

sc delete [serviceName]

After prompting that the establishment is successful, you can directly enter "net start TestService"
to start the service, or you can directly start it in the "Service" of "Management Tools". (services.msc start)

C:/Documents and Settings/Administrator>sc create

Description:
Create service entries in the registry and service database.
usage:

sc <server> create [service name] [binPath= ] <option1> <option2>...
