Solution

Here's what you have to with Selenium to get started.

Install Selenium using pip by pip install selenium in the command prompt.

Make sure you have the python path in your environment variables.

Run this script by changing the email and the password below.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
browser = webdriver.Firefox()
browser.implicitly_wait(30)
browser.get('https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=https://mail.google.com/mail/&ss=1&scc=1&ltmpl=default&ltmplcache=2&emr=1&osid=1#identifier')
email = browser.find_element_by_xpath('//*[@id="Email"]')
email.clear()
email.send_keys("email@gmail.com")  # change email
email.send_keys(Keys.RETURN)
password = browser.find_element_by_xpath('//*[@id="Passwd"]')
password.clear()
password.send_keys("password")  # Change Password
password.send_keys(Keys.RETURN)
time.sleep(10)
browser.save_screenshot('screen_shot.png')
browser.close()

And finally you can run schtask on the saved python file from the command prompt. schtask is the CRON equivalent on windows.

schtasks /Create /SC MINUTE /MO  120 /TN screenshot /TR "PATH_TO_PYTHON_FILE\FILE.py"
