Run mongodb as a replica set member by default when Window starts

Hi, I am a Windows user and I am using transactions with mongodb and I have to stop the mongodb service by:
net stop mongodb
and run as a replica set member like this:
mongod --replSet rs0
mongod is an alias for my file path to mongod.exe

I was just wondering whether there is a more efficient way to start mongodb service as a replica set member by default without being required to stop and run again because I use transactions quite offenly.

I tried to edit the mongod.cfg by adding the following lines which I found in the docs:

replication:
  replSetName: rs0

but that did not work at all. When I edit this, I have to restart my PC because mongod also stops working after I edit this, and when I restart my PC, it gets fixed by itself.

Really stuck!!
