On the User Manager main page, in the bottom part of the window it is possible to set the user, under which account, the tasks being started with operating system will be started (e.g. Resident protection). The "Anonymous" user from the "Anonymous" group is selected by default. If you would like to change this setting, select a new user from the user list in the upper part of a window and press the "Set" button.
Click on the "Close" button for saving the changes and closing this dialog box.
