When you try to install mongod as a service on Windows specifying any of the --serviceName, --serviceDisplayName or --serviceDescription options using an equal sign to separate the option name from the option value, the command line produced for the service may be missing options and/or have leftover text and the service may not be able to be successfully started.

Steps to reproduce

1. Try to install mongod as a service with as below:
C:\Mongo\bin>mongod --install --serviceName="My Service" --serviceDescription "My Service" --serviceDisplayName "My Service" --dbpath C:\mongo\data\config --port 20001 --logpath C:\mongo\logs\mongo_config.log.txt --configsvr

2. Issue the following command
net start "My Service"

3. Verify that the following error is reported:
The service is not responding to the control function

4. WORKAROUND
a. Go to the registry for this service (HKLM\SYSTEM\CurrentControlSet\services)
b. Verify that in the ImagePath after --service there's a spurious "My Service" string (without quotes)
c. remove that string and save
d. verify that the service is now starting properly.
