The report only identifies the `ionic info` command and the `wmic os get Caption` failure; no source file or test is named. Start by reproducing `ionic info` on the affected Windows setup and trace where this command is invoked. Done means identifying the cause and making `ionic info` complete successfully or report the failure clearly.
