andbootorder.TheLenovoBIOSWMIinterfaceprovidesa

simplifiedwaytochangethesesettings.Lenovohasdevelopeda

BIOSinterfacethatcanbemanipulatedthroughWindows

ManagementInstrumentation(WMI).TheLenovoBIOSWMI

interfaceenablesITadministratorstomakequeriesoncurrent

BIOSsettings,restoresettingstotheirfactorydefaults,change

singlesettings,andmodifythebootordereitheratclient

Using Windows Management Instrumentation

WMIisprovidedasastandardfeatureinmostWindows®operating

systems.Itprovidesapowerfulsetoffunctions,suchas
