AutoRestartShell controls whether the user shell,
usually NT Explorer, will be restarted if it crashes. I have seen quite a few
occasions where the shell crashes and this Windows NT / Windows 2000 registry
hack allows you to just keep on trucking. When the shell crashes, the taskbar
and desktop icons disappear. If you don't have AutoRestartShell set, you have to use keyboard shortcuts to
logoff/logon if you know them, or simply power to PC off/on. Not necessary.
Avoids losing work.
