The official answer would be to use docker on windows, but I actually would not recommend that as docker on windows has a lot of issues. The alternative is not an officially supported setup, but uses a community provided solution.
@Vadim made a toolbox for windows node operators that helps you set up multiple windows nodes. I haven’t used it mysefl, but it has gotten positive feedback from others. You can find it here.
That said, I highly recommend you get rid of the RAID0. That’s a very fragile setup and you will lose all your progress if one HDD dies. You don’t need to run 2 PC’s to run these nodes. Pick the one that uses the least power. I take it you already started the node on the RAID0. I recommend moving that node to the 12TB HDD. Wait until it’s vetted on all satellites (except stefan-benten, that one is hardly used now). Then you can start the other nodes each on its own 3TB HDD. The reason I say you should start one first and wait with the rest is because vetting would otherwise take a long time. If your first large node is up and running, that doesn’t matter much anymore as you already get as much data as possible when you have at least 1 vetted node. So the other 3 can take their time.
For followup questions regarding the toolbox, please ask in the topic I linked so @Vadim gets pinged with your questions.
