Windows 7 / Getting Started

Other Registry Entries in the Servicename Subkeys

Some drivers and services require that conditions, also known as dependencies, be met. You can find dependencies listed under the DependOnGroup and DependOnService entries in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Servicename subkey for each service or driver. For more information about using dependencies to prevent or delay a driver or service from starting, see the section titled "How to Temporarily Disable a Service" later in this tutorial. The Services subkey also contains information that affects how drivers and services are loaded. Table-3 lists some of these other entries.

DependOnGroupAt least one item from this group must start before this service is loaded.
DependOnServiceLists the specific services that must load before this service loads.
DisplayNameDescribes the feature.
ErrorControlControls whether a driver error requires the system to use the LastKnownGood control set or to display a Stop message.
If the value is 0x0 (Ignore, No Error Is Reported), it does not display a warning and proceeds with startup.
If the value is 0x1 (Normal, Error Reported), it records the event to the System Event Log and displays a warning message but proceeds with startup.
If the value is 0x2 (Severe), it records the event to the System Event Log, uses the LastKnownGood settings, restarts the system, and proceeds with startup.
If the value is 0x3 (Critical), it records the event to the System Event Log, uses the LastKnownGood settings, and restarts the system. If the LastKnownGood settings are already in use, it displays a Stop message.
GroupDesignates the group that the driver or service belongs to. This allows related drivers or services to start together (for example, file system drivers). The registry entry List in the subkey HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Control \ServiceGroupOrder specifies the group startup order.
ImagePathIdentifies the path and file name of the driver or service if the ImagePath entry is present.
ObjectNameSpecifies an object name. If the Type entry specifies a service, it represents the account name that the service uses to log on when it runs.
TagDesignates the order in which a driver starts within a driver group.
