Windows Sandbox doesn't replace Sandboxie. It's not a comparable product (yet). Windows Sandbox launches an isolated, empty VM on every launch. This allows you to install and test software, but the contents are wiped after you close Windows Sandbox. Sandboxie allows running arbitrary executable in it's own proprietary sandbox, with it's state being stored (and examineable) between runs.
