Query informationOne of the main functions of WMI is to query the WMI repository for information about classes and instances, we can call a synchronous query, or we can call an asynchronous query.
A synchronous query is a query that executes at the current execution, and an asynchronous query needs to start another thread to query, and after the query has finished, call the defined interface (similar to a callback function) to handle the query results.
Synchronous query is suitable for querying
