Here's something I found on the net about changing the shell of Windows.

Press the CTRL key while you start the computer, and then select Command Prompt Only from the Windows Startup Menu.

At the command prompt, type edit c:\windows\system.ini , and then press the ENTER to open the System.ini file in MS-DOS Editor.

To navigate through MS-DOS Editor, use the arrow keys. Under the section labeled [Boot], change the following line

shell=Explorer.exe
to:
shell=Progman.exe
Press ALT+F to scroll down to Exit, and then press ENTER. Select Yes to save the Windows\System.ini file, and to return to the command prompt.

Restart the computer. The operating system starts Program Manager.
