An all new wmic client is coming soon to replace the existing very old command line wmic binary.
The new wmic client will be a long-lived server process called by check_wmi_plus as required. This will improve performance since wmic will no longer need to be forked for each invocation. It will also allow a distributed architecture where the new wmic client could be running on a different server to check_wmi_plus.
The new solution is expected in a matter of weeks
