Microsoft.Win32.Registry.ClassesRoot.CreateSubKey and
Microsoft.Win32.Registry.ClassesRoot.DeleteSubKey.

Working with OLE StdFont and StdPicture classes
Some ArcObjects libraries make use of classes and interfaces defined within the
standard OLE libraries from Microsoft. To use these members within .NET, you
should add to your project a reference to the Stdole.dll primary interop assembly,
which is included as part of the .NET support during an ArcGIS installation.
This PIA allows you to define StdFont and StdPicture classes, for example:
[C#]
stdole.IFontDisp fnt = (stdole.IFontDisp) new stdole.StdFontClass();
fnt.Name = "Arial";
fnt.Size = 20.0F;
ESRI.ArcGIS.Display.TextSymbol textSym = new
ESRI.ArcGIS.Display.TextSymbolClass();
textSym.Font = fnt;
[Visual Basic .NET]
Dim fnt As stdole.IFontDisp = New stdole.StdFontClass()
fnt.Name = "Arial"
