Windows Desktop Search
Windows Desktop Search (or Windows Search) is a 'desktop' indexer for Microsoft Windows. In Windows XP, Search 4.0 (or Search XP) was an add-on, however Microsoft integrated Search into Windows Vista as 'part of the package'.
Windows Search stores its data in:
%Profiles%/All Users/Application Data/Microsoft/Search/Data/Applications/Windows/
Note that '%Profile%' is dependent on the Windows version.
The search index is stored in a file named Windows.edb. This file is an Extensible Storage Engine Database (EDB).
To access the Windows.edb file (on a live system) the the Windows Search service needs to be deactivated and the necessary access rights are required.
