When you get into really serious Windows development, you may well need to create NT service applications. Borland's input is half-hearted: Delphi includes support for NT service application writing, but as you work with this framework, you'll soon discover its less-polished parts!

In the TDM #69 I reviewed SvCom, "an integrated package of classes and tools for development of service applications and use of NT Security framework." (as the current SvCom web page states). Good stuff, I'm still using it for service development.
