For anyone who is interested to mine as well. I used the following cpuminer: https://github.com/pooler/cpuminer/releases

Here is a step by step tutorial how to get it up and running (assuming that you have your wallet set and rpc server is active)

Step 1
Download the latest release which is currently v2.5.0
If your OS is 32bits use the “pooler-cpuminer-2.5.0-win32.zip” file
If it’s not use “pooler-cpuminer-2.5.0-win64.zip”

Step 2
Extract the archive where it’s convenient for you

Step 3
Create a .bat file where the extracted files are located, we will use “ocean.bat” in this example.
Paste the following code:


Step 4
Impotant! make sure to make the following changes:
nthreads to the number of threads if your cpu has 8 threads try “–t 7”
myaddress  to your address
mysig to any value, basically it will appear as the coinbase signature in the blockchain


Recommandation
depending on how fast your cpu try to play with –scantime value try values between 300 and 1800


In order to check how it is going see the example below, your balance should be updated if your block was accepted.

Couple of tips:
Make sure –t argument has a slightly lower value than the number of cores/ threads that you have
I do not recommend mining on a laptop for long sessions. Make sure that CPU temperature is less than 65° to avoid damaging your hardware. You can check that with speccy.
