Also going forward you should use bitcoin-cli (as opposed to bitcoind) for commands from the command line. As eventually it won't be possible to use bitcoind to do this.
E.g.
This should return something similar to the following to the command line:
{"info":{"version":90100,"protocolversion":70002,"walletversion":60000,"balance":0,"blocks":325730,"timeoffset":-1,"connections":59,"proxy":"","difficulty":35002482026.13323,"testnet":false,"keypoololdest":1402556143,"keypoolsize":101,"paytxfee":0,"errors":""}}
If this exe is not on the path you need to CD to the relevant directory on windows.
