I'm in the same boat. I pay for a couple streaming services just because they have the shows my kid enjoys. It's so hard to find good sources for kid's shows that are actually quality and not either ancient or abandoned. Even popular/new shows can be hard to find, whereas every throwaway netflix original has seasons available from multiple different release groups.
Kid's shows are really the weakspot of piracy for me. Thrift store DVDs help a lot, but it's always older stuff and never whole seasons of shows.
I've used it on probably 10+ windows systems that I've had to refresh/set up for various needs and people. I've never had it fail on any flavor of 10/11.
