Explanation (?): |
The portable media serial number service is used for digital rights management (DRM) technology that allows an author of multimedia files to restrict usage of those files to guidelines they lay out, instead of it being freely distributable. The purpose of this technology is to reduce piracy of copyrighted materials. This service holds the purpose of representing a digital mulitmedia device by an identification number. This allows a media playing program to correctly distinguish the rights that the portable media player holds, and allows it to act accordingly. This technology is only used by Windows Media Player though, and the DRM actions are restricted to Windows Media formats, such as Windows Media Audio (.WMA) and Windows Media Video (.WMV) files. It is best that you set this service to manual, and it will activate if it is ever needed. |

"I must not fear. Fear is the mind-killer. Fear is the little death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past, I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain." -- The Bene Gesserit Litany of Fear from the novel Dune by Frank Herbert
