Without this adjustment, it is generally not possible to disable keys in Windows 7 and Windows
Server 2008. Users can then use the shortcut key <Ctrl+Alt+Del> in WinCC Runtime to perform
all related actions, e.g., lock computer, change user, log off, change password, start Task
Manager.
Warnings with the DCOM configuration
When the "Dcomcnfg.exe" program starts, there may be warnings about unregistered AppIDs
of WinCC components. This reaction has no effect on the functional capability of the software.
The warnings can be ignored.
Changing the screen settings
Changing the color palette
If you change the color palette via the Windows Control Panel, you should expect color changes
and poorer legibility of the text. When creating the project, therefore, be sure use the same
color palette that will be used in runtime.
Changing the resolution
In order to use a different resolution in the destination system, use the "Adapt Picture" or "Adapt
Size" functions for pictures and windows. These settings can lead to blurred displays in runtime
and increased system loads.
Operating system with multilanguage installation: wrong language in message boxes
In message boxes in which the user must respond with Yes/No, OK/Cancel, etc., the buttons
are always labeled in English in both CS and RT. This characteristic is independent of both
the operating system language set and the WinCC language.
Novell Netware clients
WinCC should not be installed on a system together with the Novell client software.
The installation of WinCC can have the effect that it is no longer possible to log on to the Novell
system or the lock the keyboard during runtime.
We recommend you not use the Netware client software or use the Microsoft client for Netware.
Notes on Internet Explorer
Web client: Display of ActiveX controls in Internet Explorer
ActiveX controls are disabled in Internet Explorer by default. For this reason, the WinCC
controls are not displayed correctly in Internet Explorer on a Web client.
To display the WinCC controls correctly, add the Web server as a trusted website and enable
the ActiveX controls only for the "Trusted sites" zone.
To continue protecting Internet Explorer from foreign ActiveX controls, check that the restricted
security settings still apply to the other zones after making the changes.
