If you want to obtain (localized) names of Unicode characters, instead calling this function you can also load strings from the same place the function loads them. On Windows 7 it means from file \System32\{Culture}\getuname.dll.mui. ({Culture} is name of culture you want to obtain localized resources for e.g. en-US). An advantage of this approach is that you can choose culture without need to switch current Windows language (Windows Ultimate edition only).

     ''' Localized name of character represented by <paramref name="codePoint"/>. The name is localized to current system locale, not to current thread UI culture.

     ''' <para>This function relies on undocumented Windows API <c>GetUName</c>. It is possible that this API will be changed or removed in future version of Windows and this function will become slow and start returning nullls for all calls. It can also possibly carsh your application or system. Use on own risk.</para>

EventLogSession from the namespace System.Diagnostics.Eventing.Reader can be used in most cases (Windows Vista and above only and .NET 4 or above. This throws a PlatformNotSupportedException on Windows XP and Windows 2003 with .NET 4)

BuildExplicitAccessWithName does not appear to work on x64 bit systems. Usually causes an AppCrash in compiled .net apps. Same code works when compiled as x86 app.

Most (but not all) functionality can be accessed using classes in the System.ServiceProcess namespace.
