I just installed mongoDB in my windows machine

```
MongoDB version       : Windows 64-bit 2008 R2+ release 3.0.4
OS Version            : Microsoft Windows 7 Ultimate 64-bit
Installation Directory: "C:\Program Files\MongoDB"

```

instead of creating the database in default `C:\data\db\`, I created a directory in the installation directory, i.e. `C:\Program Files\MongoDB\data\db`. Now I can run `mongod` server by the command 

```
mongod --dbpath "C:\Program Files\MongoDB\data\db"

```

If I run only `mongod` it throws an exception saying 

```
[initandlisten] exception in initAndListen: 29 Data directory C:\data\db\ not found., terminating

```

So, apparently the default dbpath is set to `C:\data\db\`. Each time I run mongod, I have to explicitly specify `--dbpath`

Is there a way to override the default `dbpath` value? I have tried following [this answer](https://stackoverflow.com/a/25303400/1355722), which solved the issue. But as there were no default `mongod.cfg` file, now I have to tun the command:

```
mongod --config "C:\Program Files\MongoDB\mongod.cfg"

```

Which doesn't help much, because now I have to explicitly specify `--config` each time. All I want to do is just type `mongod`, each time I want to start mongo server. How can this be done?
