由于屏幕保护程序的设定界面因操作系统而异，无法精确指定，以下代码仅提供一个参考：

使用bat档：

@echo off echo Setting screensaver to 'Bubble'... reg add 'HKEY_CURRENT_USER\Control Panel\Desktop' /v SCRNSAVE.EXE /t REG_SZ /d '%systemroot%\system32\Bubbles.scr' /f reg add 'HKEY_CURRENT_USER\Control Panel\Desktop' /v ScreenSaveTimeOut /t REG_SZ /d 60 /f echo Screensaver set to 'Bubble' with timeout of 1 minute.

timeout /t 14400 echo Waking up the machine... rundll32.exe user32.dll,LockWorkStation

使用Python：

import winreg

Set screensaver to 'Bubble' with timeout of 1 minute

screensaver_path = '%systemroot%\system32\Bubbles.scr' screensaver_timeout = 60 screensaver_key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, 'Control Panel\Desktop', 0, winreg.KEY_WRITE) winreg.SetValueEx(screensaver_key, 'SCRNSAVE.EXE', 0, winreg.REG_SZ, screensaver_path) winreg.SetValueEx(screensaver_key, 'ScreenSaveTimeOut', 0, winreg.REG_SZ, str(screensaver_timeout)) winreg.CloseKey(screensaver_key) print('Screensaver set to 'Bubble' with timeout of 1 minute.')

Wait for 4 hours and wake up the machine

import time import ctypes time.sleep(14400) print('Waking up the machine...') ctypes.windll.user32.LockWorkStation()
