The Win32_ShadowContext class specifies how a shadow copy is to be created, queried, or deleted, and the degree of writer involvement.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties and methods are in alphabetic order, not MOF order.
