Desktop Experience

PowerShell : Desktop Experience Feature

English Today I find a strange behaviour, my Office 2010 can not browse to the SharePoint 2010 document library. In short, I can not save my document directly to SharePoint 2010. Office 2010 provide Save and Send functionality, which should give me functionality to save directly to SharePoint 2010 as what it does in previous version; so what could be the problem? Saving to SharePoint 2010 document library requires WebDAV functionality via Web Client service.
