style(windows): satisfy rustfmt on the uninstall() teardown comments

rustfmt 1.9.0 aligns standalone // lines out to the column of a preceding
trailing comment, so the two-line fullscreen note placed right after
`set_captured(...); // ...` failed `cargo fmt --check`. Make the first note a
leading comment so no standalone comment follows a trailing one.
