if you want to restart an instance of
Windows Explorer, you should use the official way to shut down
Explorer, rather than killing it from Task Manager! To shut down
officially, hit Start->Shutdown (or Turn Off Computer on Windows
XP), then while holding the control shift and alt keys, click cancel on
the shutdown dialog. To start a new instance of Windows Explorer, bring
up Task Manager by holding the control and shift keys, then hit escape.
In Task Manager, choose File->New Task and enter "Explorer.exe".
This will have restarted Windows Explorer properly.
