Default to the Documents Library

Default to the Documents Library.
These tips apply primarily to Windows 7

In Windows 7, when you launch Windows Explorer, the view automatically 

defaults to the Libraries Folder, which for many users is not very 

useful. Busy types will typically drill straight to the Documents 

Library from there. Save a click by instructing Explorer to default to 

the Documents Library. To do this, right-click on the Windows Explorer 

shortcut (the taskbar shortcut won’t work). In the Target field, type or 

paste: %windir%\explorer.exe ::{450D8FbAAD25-11D0-98A8-0800361b1103} 

Finally, replace the icon in the taskbar with your tweaked shortcut.
