title: How to change mouse scroll speed using batch file in Windows?
body: <p>I don't know which software did the trick, but my mouse scroll speed is constantly being changed to '1', after I set it to '3', maybe an hour later, it is reset to '1' again, which makes browsing code or webpages quite inconvenient.</p>
  
  <p>I don't want to go to control panel &rarr; mouse too often. So how can I do it on the command line?</p>
