Bare minimum system requirements for Core
Bare min setup uses the bitcoin's feature called pruning.
In prune mode your node will sync the whole blockchain (the data on the website is a bit outdated, it's closer to 400GB now), but it has to start from block 0. If you set your pruning to 5 GB, it will start syncing from block 0 till the 5GB limit and after that will still sync (so your internet connection has to go through whole 400GB) but will delete older blocks. So at the end your history will be only latest few dozen k blocks. But your node in the process will &quot;parse&quot; all the 400+ GB of data, just keeping latest 5GB at a time.
Yes, bitcoind/bitcoinqt works on windows 10 :)
