How can I update npm on Windows?

Answer 1

This works fine for me to update npm on Windows 7 x64:

• Windows start
• All Programs
• Node.js
• Node.js command prompt (alternative click)

• Run as administrator

  $ npm -g install npm

• remove C:\Program Files\nodejs\npm.cmd the new npm will be at C:\Users\username\appdata\roaming\npm\npm.cmd

Hope this helps.
