How is it possible to enable / disable the windows keys (like Alt-Tab & Ctrl-Alt-Del) on a WinCC OA client?
Example :
* a process operator (logged in as OPERATOR) may not be able to use these keys
* a maintenance engineer (logged in as ADMINISTRATOR) must be able to use the windows keys
Any hints?
OS is Win7.

Hello,
these functions are operating system functions for the window handling.
If you want to disable these functions you have to modify some registry keys. The modification can be made with batch-files which are started using the system()-command in WinCC OA.
Maybe you can also define at the user-settings in the operating system that using these functions is not allowed. To get further information please get in contact with your system administration.
