If only it was windows 8.1.
I believe it should be fine all the way back to Windows XP as far as the batch scripting goes.... and if its XP64; I think it would work this exact same copy of miner apps and everything....
Not that I would consider ever running that OS since I switched from it to 7

I'm running vista and it gives a higher hashrate.

Where is your delay that is needed for ccminer before running the next algo?......is it the wait command?
