Start the miner from the commandline or a .bat/.sh script (run minerd -h or cpuminer -h for a list of what those arguments mean). Examples: minerd.exe -t 3 -a yescryptr16 -o stratum+tcp://crypto.n-engine.com:6233 -u xxxxx_your_wallet_xxxxx -p c=YTN cpuminer.exe -t 3 -a yescryptr16 -o stratum+tcp://crypto.n-engine.com:6233 -u xxxxx_your_wallet_xxxxx -p c=YTN
I suggest do not use -t option with cpuminer.. it will automatically the set the best number of mining threads. Normally no of logical processors and not cores. You can find your processor details in Task manager in win OS.
