It also helps find and preview documents, e-mail (including signed e-mail messages), music files, photos, and other items on the computer. The search engine in Windows Search 4.0 is a Microsoft Windows service that is also used by programs such as Microsoft Office Outlook 2007 and Microsoft Office OneNote 2007. Autotuning Diagnostics in SP2 now interprets current network conditions when implementing Windows scaling. This feature includes full netsh support.
