I know there are more direct sources. But for the amount of mental energy I want to invest into Windows, discovery through torrents is far easier. My workflow consists of creating a VM, installing / updating everything, taking a snapshot, then removing network access before it gets access to Samba shares with any private information.

I suppose I might still be worried about targeted offline-acting malware if I were using Windows to control some enrichment centrifuges or something. But apart from that, I'm fine with whatever inhabitants it may have frolicking in their isolated jungle.
