Upgrade to the Latest Revision of MongoDB in windows

Upgrade to the Latest Revision of MongoDB in windows

First, My mongodb is very simple- single DB so I just follow the instruction -

https://docs.mongodb.com/manual/tutorial/upgrade-revision/  -
Replace the Existing Binaries

1. Download the binaries for the latest MongoDB revision from the MongoDB Download Page and store the binaries in a temporary location. The binaries download as compressed files that uncompress to the directory structure used by the MongoDB installation.
2. Shutdown the instance.
3. Replace the existing MongoDB binaries with the downloaded binaries.
4. Restart the instance.

My steps :
          1. I download the latest revision of MongoDB -3.4. 
          2. Install MongoDB 3.4 

      3. change path
          3.1 control panel
          3.2 System --> Change settings
          3.3 Advanced --> Environment Variables...
          3.4 System Variables -->[Path]
       

         3.5. change MongoDB path from 3.0 to .3.4 and then save. 

         

         3.6 open command prompt (cmd) and check version --- Mongod -version
