Methods

The MSFT_Providers class inherits the methods of the IUnknown interface.

In addition, MSFT_Providers defines the following methods.

Method	Description
Load	Loads a specific instance of a provider.
Resume	Resumes execution of suspended providers.
Suspend	Suspends execution of providers.
UnLoad	Unloads the COM server associated with a specific instance of a provider.

Properties

The MSFT_Providers class defines the following properties.

HostingGroup

Data type: string
Access type: Read-only
Qualifiers: Key

Defines the second component of the __Win32Provider HostingModel property when the hosting model is one of the following:

LocalSystemHost
NetworkServiceHost
LocalServiceHost
LocalSystemHostOrSelfHost
NetworkServiceHostOrSelfHost

The hosting group defines a grouping of providers in a separate Wmiprvse.exe process. Providers that share the same hosting model and hosting group share the same service host process.

HostingProcessIdentifier

Data type: string
Access type: Read-only

Process identifier that hosts the specific instance of the provider.

HostingSpecification

Data type: uint32
Access type: Read-only
Qualifiers: Key

Defines the first component of the __Win32Provider HostingModel property. The hosting property is defined to be one of the value types in the following table.

Value	Meaning
WmiCore	Activate provider in host to the WMI service. This hosting model is only supported for operating system components. Attempts to register providers with WmiCore fail with WBEM_E_ACCESS_DENIED.
WmiCoreOrSelfHost	Activate provider in host to the WMI service or as local server. This hosting model is only supported for operating system components. Attempts to register providers with WmiCoreOrSelfHost fail with WBEM_E_ACCESS_DENIED.
SelfHost	Activate provider as a local server implementation.
Decoupled:Com	Activate provider as a decoupled COM provider. For more information about decoupled providers, see Incorporating a Provider in an Application.
Decoupled:NonCom	Activate provider as a non-COM event provider.
LocalSystemHost	Activate provider in the provider host process that is running under the LocalSystem account. Windows XP: LocalServiceHost is the default configuration that WMI sets when the HostingModel property in __Win32Provider is NULL.
LocalSystemHostOrSelfHost	The provider is self-hosted or loaded into the Wmiprvse.exe process running under the LocalSystem account. Windows Server 2003: LocalSystemHostOrSelfHost is the default configuration that WMI sets when the HostingModel property in __Win32Provider is NULL. Because LocalSystem is a highly privileged account, an entry is generated in the Security Event Log to notify administrators of a provider running in this trusted status.
NetworkServiceHost	Activate provider in the provider host process that is running under the NetworkService account.
LocalServiceHost	Activate provider in the provider host process that is running under the LocalService account.
NetworkServiceHostOrSelfHost	The provider is self-hosted or loaded into the WmiPrvse.exe process running under the NetworkService account. NetworkServiceHostOrSelfHost is the default configuration when the HostingModel property in __Win32Provider is NULL. Because NetworkServiceHostOrSelfHost is the default, providers from earlier operating systems can continue to work in Windows Vista, Windows Server 2008, and later operating systems. Windows Server 2003 and Windows XP: This hosting model is not available.

Locale

Data type: string
Access type: Read-only

The language locale. For Microsoft locale identifiers, the format of the string is "MS_xxxx", where xxxx is a string in hexadecimal form that indicates the LCID. For example, the American English locale identifier is "MS_409".

Namespace

Data type: string
Access type: Read-only

Namespace associated with a specific provider instance.

Provider

Data type: string
Access type: Read-only
Qualifiers: Key

Name associated with a specific provider instance. The name is identical to the __Win32Provider property.

ProviderOperation_AccessCheck

Data type: uint64
Access type: Read-only

Number of calls to IWbemEventProviderSecurity::AccessCheck.
