A fancy way would be to look at the remote registry, starting with a call to RegConnectRegistry(), then look at its HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ProductOptions.

An easy way would be to run a bat file that plops %OS% into a file which you then pull back.
fire a ping command and redirect the output to a file and read it and based on the ttl you can get the information
