It's the little things we take for granted such as pulling up Task Manager when the explorer.exe process has crashed.

On a standard workstation, I would hit Ctrl-Alt-Del, Task Manager would launch which would then allow me to kill the process.

With explorer.exe terminated:

- select the File Menu
- select New Task
- in the Open field, enter:  explorer.exe
- click Ok

And like magic, everything is as it should be.

But what do you do when explorer.exe crashes in an RDP / Terminal session?

Hit Ctrl-Alt-End, select Task Manager and follow the above instructions for terminating and launching the explorer.exe process.
