Desktop and Taskbar
Under Desktop and taskbar in separate process, you can configure a setting that has an important effect on the stability of your system. By default, the desktop, taskbar and the Explorer are all run in a single process. When the Explorer crashes, this also crashes the desktop and the taskbar. To prevent this, you can have the desktop and taskbar run in a separate process. This requires 8 MB of additional memory.
It is best to select the options under Restart desktop and taskbar automatically to ensure that the desktop and taskbar are restarted automatically if they crash so that you can continue to use the system.
