Node and Npm on Windows

After install NodeJS and NPM on Windows, remember to verify if nodejs and npm directory is on your System PATH.

In my case, nodejs was installed on "C:\Program Files\nodejs", but the npm packages with -g argument was installed on "C:\Users\USERNAME\AppData\Roaming\npm", i created a user variable with reference for folder.

Check the configurations to use commands from command-line, like npm and grunt commands.
