Microsoft Corporation first introduced indexed search as Windows Desktop Search which was available as part of the MSN Toolbar browser helper object as an add-on for Windows XP and Server 2003. In Windows Vista and 7 and 8, indexed search is a standard component (built-in) and known as Windows Search.

Windows Search consists of both a one-time construction of an index and the continuous monitoring thereafter for addition and deletion of resources. It was designed to include a development platform and user interface so that third-party developers could create applications to interact with it. It allows applications not only to use the contents of the Windows Search index but to enhance the Search Service by defining "filters" for new types of files that enable it to search within those files, so that, (for example), searching for "Michael Jackson" will find references not only in text documents or web pages but also in music files that list "Michael Jackson" as the artist in their internal descriptive elements.

A "namespace" is a concept deeply involved in object-oriented programming, having to do with how widely a name (for an executable module or for a container of data) used within a program has to be kept unique. That is, within a namespace the same name cannot be used for two different things but in different namespaces it can be. The Windows Search Namespace Manager is therefore related to the interaction of third-party applications with the Windows Search Service.

Third-party applications that have been mentioned in connection with this module include Verizon FIOS Media Manager, (retired by Verizon in November 2013), which was a PC and Mac application allowing FIOS set-top users to watch home movies and videos on their TVs which they had downloaded from the Internet, but also to buy movies and TV shows from Verizon and watch them on their computers and mobile devices as well as their TVs. This involved adding to Windows Search the filters needed to find information within these additional types of downloaded files as well as requesting search results from it.

If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!

All comments about MSNLNamespaceMgr.dll:
This is a special .dll file (Dynamic Link Library), which starts automatically when programs are launched. So it can monitor or manipulate all of your program starts. The program has no visible window. The service has no detailed description. File MSNLNamespaceMgr.dll is not a Windows core file. It monitors program starts. Therefore the technical security rating is 55% dangerous. John
Comes with the MS O.S. but makes searching slow, even more so while trying to open/browse files in MS Office
