Maybe try mine, it's specialized in older hardware (CPU and GPU). I'm mining right now at 400+ h/s with my HD7850 2G
https://github.com/jceminer/cn_gpu_minerIt's almost getting annoying to read there's no decent CN miner for older hardware while my topic is on the exact same channel as this one and online for something like 6 months...
I am on win 7 64bits. Gonna wait couple of weeks more and if nothing good on 7 comes than go 10.
P.S. It's strange how it is "specialized" in older hardware but needs win10. Older hardware usually runs on 7.
