Most business environment have a (somewhat) restricted workspace. The IT department is always discussing the need of the Windows Task manager for end-users. This is because the Windows Task Manager is unmanageable and gives away a whole lot of information about performance, services, processes and possibly the name of other logged on users on that machine. All kinds of information not necessary for an end user to know. For that reasons the IT department frequently prevents the use of the Windows Task Manager. This also prevents a user to close an application that is not responsive anymore.
The Simple Task Manager gives back that functionality to the user without all the noise and showing unnecessary/unwanted information. A user gets an overview of their application windows with the possibility to put the application in front of all the other applications or simply end the task. This will prevent the need for a user to call the servicedesk to simply close a stuck application.
