Python中subprocess.Popen.terminate有什么问题？

Question

我想用Python脚本在Windows10上运行并关闭资源管理器。但我不能。 subprocess.Popen.terminate（）不关闭资源管理器。怎么了

import subprocess
 
folder = r'C:\Users\issy\Documents'
pidcheck = 'tasklist | find "explorer"'
subprocess.check_output(pidcheck, shell=True)

Out[6]: b'explorer.exe 18568 Console 3 148,416 K\r\n'

Popen_explorer = subprocess.Popen(['explorer',folder])
Popen_explorer.pid

Out[8]: 2176
 
subprocess.check_output(pidcheck, shell=True)

Out[9]: b'explorer.exe 18568 Console 3 150,416 K\r\n explorer.exe 11732 Console 3 64,696 K\r\n'
# pid is different. 11732 is true. subprocess.Popen.pid shows wrong id 2176.

Popen_explorer.terminate()
# explorer does not close.
