Cargo Features

[dependencies]
windows-dll = { version = "0.4.1", default-features = false, features = ["windows", "winapi"] }
default = winapi

The winapi feature is set by default whenever windows-dll is added without default-features = false somewhere in the dependency tree.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
