Can anybody please advise where I can download the free version of the Quartus Software that is compatible with both MAX II as well as Stratix II devices but works on Windows 10
Unfortunately the Quartus II softwares that support Stratix II are obsolete and we do not provide them anymore. However the Quartus II Web Edition 15.0 supports Max II and is available in the FPGA Download Center: https://fpgasoftware.intel.com/15.0/?edition=web&platform=windows
However I suggest that you get the latest Quartus Prime Lite edition software since it supports Max II and there are many improvements.
