Ok I got it working this is the bat file, seems to be stable, not sure if I can get more out of that, G4400 Pentium

cpuminer-sse2 -t 2 -a yescryptr16 -o mine.nlpool.nl:6333 -u YaQWNazgdxoC9vtgJt7Dmmp1i8mvcf5Ae7 -p c=YTN --cpu-priority 1

Any ways to know wich worker is doing what, identify it?

Will be sending some more your way
