The first time I used windows 7 ,I found the Windows Explorer will open the Libraries by default.
If you want Windows Explorer open “my computer” by default,please hold down the Shift key on your kerboard,then right-click the icon of Windows Explorer and select Properties.

In the next window ,change the Target field from “%windir%\explorer.exe” to:
%SystemRoot%\explorer.exe /e, ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}
Then the next time Windows Explorer will open “My computer” by default.

Awesome, thanks.
As soon as I got Windows 7 I wanted to change that.
Thanks
I’ve used this one since XP.
%windir%\explorer.exe /s, /e, /select, c:
