Registry Value Exists Rule
The Registry Value Exists basic rule in System Center Updates Publisher is used when creating or modifying software update definitions. It is used primarily as an applicability or installed type rule. A specific registry key is verified with what is found on a scanned client. If the rule does not pass verification, the software update is considered not applicable or not installed on the computer. The Registry Value Exists rule has the following configuration settings:
Registry Path: Specifies the path to a registry key. For example, HKEY_LOCAL_MACHINE\Software\MyCompany\MyTool\Mykey. This is a required field.
Registry value: Specifies the value for the registry key configured in the Registry Path field. Leave this field blank to specify the default value.
Use 32-bit Registry: Specifies whether registry hive detection will always occur in 32-bit or determine whether the computer is 64-bit or 32-bit and detect the registry hive accordingly. By default, the Use 32-bit check box is not enabled and both 64-bit and 32-bit registry detection are supported.
Registry value type: Specifies whether the registry key value is REG_BINARY, REG_DWORD, REG_EXPAND_SZ, or REG_SZ. This is a required field.
