What you need to manage your Intel C600 Series Chipset RAID array from within Windows is the complete package of the Intel(R) Rapid Storage Technology "Enterprise Edition". It contains the Intel RSTe Software and the RSTe drivers.
You can download the RSTe package v3.6.0.1093 from this Intel Download Center page: https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3449&DwnldID=22502&keyword=Intel+Rapid+Storage+Technology+enterprise+(Intel+RSTe)&lang=eng
