Resolution

Go to Task Manager and in the Services tab find Windows Management Instrumentation Service and find the Process ID (PID) of this service process. Note down the process ID and come to details on the task Manager and kill the process. Leave the Windows Management Instrumentation Service start state to be disabled and run the Exchange Server Cumulative Update setup again either through Graphical user interface or command line and this time the error won’t come up.
