NVM lets you manage and install different versions of NodeJS easily. To grab the Windows version of NVM head here.

In the README when you scroll down you will see a blue Download link, click that and you will be taken to the corresponding downloads page. For a painless install we recommend using the nvm-setup.zip as it takes care of all necessary steps for you. Once you have it downloaded simply extract and run the installer.

Once it is set up go to your command line and type nvm to make sure it installed correctly.

• nvm install <nodeversion> , example: nvm install 5.7.0 (Installs node version 5.7.0 on your machine)
• nvm uninstall <nodeversion> , same example as before with the only difference being the command.
• nvm use <nodeversion>, example: nvm use 4.3.0 (This will use node version 4.3.0 assuming you have it installed)
• nvm ls, will list all available node versions

There are a few more commands you can use with NVM for windows but these are the most common ones.
