Download the .zip file of Node.js that you want to run on your Windows system from https://nodejs.org/en/download/. This should download a file such as node-v20.10.0-win-x64.zip. unzip the .zip file.

You should now be able to run the node --version command and the version of Node.js that you downloaded and unzipped should be displayed.
