you can put this script whatever you want, but second script c:\miner\start_sgminer.bat is your sgminer script containing:
C:\miner\sgminer.exe --kernel quarkcoin -o stratum+tcp://quark.eu.nicehash.com:3345 -u xxx
Remember to delete sgminer.conf file, otherwise it won't run
Ok, thanks.
It is running fine now.
