I'm sure you agreed to give them a non-exclusive, world-wide, royalty-free, un-fuck-with-able license (or some such) to any data saved to your hard drive when you accepted the terms of use for Windows. /s
But now I'm curious if there's case law around the question of passwords being copyrighted. That might be a decent avenue of protection but the aforementioned agreement probably
supersedes it.
From a quick search it doesn't look like they are, and there's no explicit law on who "owns" a password. Consensus right now is to operate under the assumption that the maker of the software is the owner of the password, not the user.
