Remarks

Loads a system profile identified by its GUID. The GUID is passed as a string. The list of profile IDs contains only IDs for versions 4, 7, and 8. Version 9 does not have a predefined list of IDs. Only system profiles have IDs. For more information, refer to the Microsoft documentation for IWMProfileManager.LoadProfileByID.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
