Previously, on some versions of Windows, the WMI API call may not clean data structures correctly. As result the Agent may send extremally high values for CPU load, RPC latency and so on.

Now Windows Agent cleans WMI data structures automatically and also cuts all received data according to the length defined by Windows API thus preventing such type of error.
