<p style="margin-left: 25px">Value to set. To clear a leaf node’s value, set *varValue*’s type to `VT_NULL`.</p>

## Return Value

A value of S\_OK indicates that the value was set successfully. CFGMGR\_E\_COMMANDNOTALLOWED indicates that this node does not support the **ICSP::SetValue** method, or that it's an internal node.
