If you are using NT4 on a system that is low on available RAM, you can gain between one and three megabytes of free RAM by right-clicking on the Taskbar and selecting 'Task Manager'. Click on the 'Processes' tab, select 'Explorer.exe' and click on 'End Process'. Click Yes when the dialog box appears. All the Desktop icons, the Taskbar, and the Start menu will disappear from the screen. To restore the Desktop, click on 'New Task' in the Task Manager and type in 'Explorer.exe'. This will bring everything back.
