The default global path for npm under windows is What?

  node.js, question

I accidentally changed the global path with npm config set prefix. I wanted to change it back, but I couldn’t find the original default path. It’s no use uninstalling nodejs and reloading. Now I execute npm install -g yo under the root directory of e-disk and directly install yeoman on e-disk

“C:\Users\xxx\AppData\Roaming\npm”
