The CertUnregisterPhysicalStore function removes a physical store from a specified system store collection. CertUnregisterPhysicalStore can also be used to delete the physical store.

BOOL CertUnregisterPhysicalStore(
  [in] const void *pvSystemStore,
  [in] DWORD      dwFlags,
  [in] LPCWSTR    pwszStoreName
);

Parameters

[in] pvSystemStore

A pointer to an identifier of the system store collection from which the physical store is to be removed. It is either to a null-terminated Unicode string or to a CERT_SYSTEM_STORE_RELOCATE_PARA structure. For information about using the structure and on appending a ServiceName or ComputerName to the end of the system store name string, see CertRegisterSystemStore.

 The physical store is first removed from the system store collection and is then deleted.

[in] pwszStoreName

Null-terminated Unicode string that contains the name of the physical store.
