How do I set up a Lightning Node on Mainnet using windows? I want to set up a lightning node on windows. I have found lightning-app which seems to work only on testnet. help me finding a good guide to set up a lightning node on windows.

the reason I am insisting in the frustrating windows platform is to make it familiar with other people showing it really works on mainnet and setting it up for non-programmers. but I have found some guide on medium which shows how to set it up on testnet.
Try Eclair.

It has a nice GUI, runs on Windows, and just a few days ago they have announced a new version that officially supports mainnet usage.

It requires a Bitcoin Core node to runs alongside it, and a little configuration.
