Then, to install and use this upgrader tool, run the following command (also from an elevated PowerShell or cmd.exe). Note: If you're running a Node version lower than 4.0, please use
firstname.lastname@example.org, which is the last version to support older versions of Node.js.
npm install --global --production npm-windows-upgradenpm-windows-upgrade
Want to just install the latest version? Sure:
npm-windows-upgrade --npm-version latest

If you have trouble with the script, consider adding parameters manually. A common issue is that the script fails to find npm (and therefore doesn't know where to install it) - in that case, pass the location manually.
npm-windows-upgrade --npm-path "C:\nodejs"
To manually specify a version to install, pass the
npm-windows-upgrade --npm-version 3.5.0
To override the internet connection check, pass
--no-dns-check. To disable the initial prompt, pass

Please do report your issues on GitHub. There are a bunch of Windows versions, hundreds of different ways to install Node and npm, and it's likely that this script won't work with a few of them. If you run into trouble and need npm upgraded as soon as possible, please follow the manual instructions.

Chances are that you attempted to upgrade npm before, it somehow failed, and you then went looking for this tool. If the tool fails to upgrade, it may be troubled by partial changes done during
npm install npm or
npm upgrade npm. In that case, you will have to completely uninstall Node:
Uninstall, not the
%programfiles%\nodejsand delete the entire folder.
PATHand remove everything that references npm (to do so, hit "Start" and search for "Environment Variables").
npm install npm.
