WMI Errors: WMI (Windows Management Instrumentation) is the Microsoft implementation of Web-Based EnterpriseManagement (WBEM), an industry initiative to develop a standard technology for accessing management information in an enterprise environment. WMI runs as a service, and can be disabled. One of the areas WMI manages is performance counter information, loading the performance library using ADAP ( AutoDiscovery/AutoPurge ). If you get errors such as "WMI ADAP was unable to load the perfproc.dll performance library due to an unknown problem within the library: 0x0", or "WMI ADAP was unable to load the winspool.drv performance library due to an unknown problem within the library: 0x0 " you can run the following two commands from a command prompt:
winmgmt /clearadap
winmgmt /resyncperf -p XXX (Where XXX is the PID of the WIM process)
The first command deletes the ADAP information in the registry, the second command invokes the AutoDiscovery/AutoPurge (ADAP) mechanism of WMI to reset counter information. The PID of the winmgmt process can be found in Task Manager, next to winmgmt.exe in the processes tab. You can also disable performance counters (see below), or the whole WMI process. Another option is to disable a particular counter, using the following regi
