By default, the Windows NT 4.0 Desktop, Taskbar, and Explorer run in a single process using multiple threads. If you modify the registry, enabling the DesktopProcess entry, the Taskbar and Desktop will run in one process with each instance of Explorer in a separate process. Each new instance of Explorer.exe will use its own thread. The setting can be verified when two instances of Explorer.exe are visible using Pviewer.exe from the Windows NT 4.0 Resource Kit or the Process tab of the Windows NT 4.0 Task Manager.
This configuration is enabled on a per-user basis by modifying the registry as follows:
