NVM for Windows
A node.js version management utility for Windows written in Go
... to test a module you're developing with the latest bleeding edge version without uninstalling the stable version of node, this utility can help. Please note that any global npm modules you may have installed are not shared between the various versions of node.js you have installed. Additionally, some npm modules may not be supported in the version of node you're using, so be aware of your environment as you work.
