title: pyw file opens visual studio instead of running the program
body: <p>So I have a .pyw file, default program to open it is pythonw.exe, but instead when I run it it opens visual studio. Maybe a behind the scenes error? 
  Program was set up in the task scheduler with highest permissions to access hosts file in windows. The test path works fine.</p>
  
  <pre><code>import time
  from datetime import datetime as dt
  
  
  
  # Temporary hosts path to test
  hosts_temp = r"C:\Users\letto4135\Desktop\python_programs\web_block\hosts"
  
  # Hosts path in windows
  hosts_path = r'C:\Windows\System32\drivers\etc\hosts'
  
  # Redirect to this IP
  redirect = "127.0.0.1"
  
  # List of Websites to block
  website_list = ['www.facebook.com','facebook.com']
  
  
  
  while True:
      # If between time, block sites
      if dt(dt.now().year,dt.now().month,dt.now().day,8) &lt; dt.now() &lt; dt(dt.now().year, dt.now().month,dt.now().day,16):
          with open(hosts_path,'r+') as file:
              content = file.read()
              for site in website_list:
                  if site in content:
                      pass
                  else:
                      file.write('\n' + redirect + ' ' + site)
      # If not between time allow sites
      else:
