When there are multiple processes with the same name, WMI represents those after the first instance as `process-name#index`. So to get them all, rather than just the first one, the query needs to be a wildcard search.
When there are multiple processes with the same name, WMI represents those after the first instance as `process-name#index`. So to get them all, rather than just the first one, the query needs to be a wildcard search using a `%` character.
Please note that in Windows batch scripts (and when using the `cmd` command prompt), the `%` character is reserved, so it has to be escaped with another `%`. For example, the wildcard syntax for searching for all firefox processes is `firefox%%`.
