python
import psutil

def find_sihost_process():
for proc in psutil.process_iter(['pid', 'name']):
if proc.info['name'] == 'sihost.exe':
return proc.info['pid']
return None

sihost_pid = find_sihost_process()
if sihost_pid:
print(f"sihost.exe process found with PID: {sihost_pid}")
else:
print("sihost.exe process not found.")


In the above sample code, the `psutil` library is used to search for the sihost.exe process and retrieve its PID (Process ID). The `find_sihost_process()` function iterates through all running processes and checks if the process name matches ‘sihost.exe’. If a match is found, the function returns the PID; otherwise, it returns `None`. The main code calls this function and prints the result.
