title: ng not recognized after installing angular CLI
body: <p>when I am trying to install angular CLI in my computer with Windows 10 64 bit OS, it always ended up like as seen in the screenshot:</p>

  <p>after installing it and try to check the version using 'ng -v', I get message:</p>
  
  <p>'ng' is not recognized as an internal or external command, operable program or batch file.</p>
  
  <p>I also noticed that there are files that are not included in the installation not like the one in the tutorial that I'm following in this link:</p>

  <p>I also tried searching for possible solution on this but unfortunate to find one. have somebody experienced this too and found solution?</p>
