How to check the version of Meteor.js on Windows
In the project folder, in command line try this...
meteor --version
If you installed the Windows version via the MSI, you can look in the standard windows add/remove programs wizard to see what version you have.
The version of Meteor for Windows you are using does not use the 'warehouse' and therefore Meteor always uses a version of 'none'. There is an experimental version of Meteor for Windows which does use the warehouse available at: https://github.com/sdarnell/meteor/wiki/Windows
cd into your hidden .meteor folder and open up the release file inside the folder, it will have the version number
$ cd .meteor
$ nano release
