Hi all, I came accross a problem disabling the Windows keys combination, i.e. ALT+CTRL+DEL, ALT+TAB, etc. I already found a nice script that does the job and it appears to work well. I used this thread DisableKeysWin7 and Siemens FAQ 44027453. The problem I have is that I am using this in Runtime on a touch screen panel. Whenever a user needs to login or input a value, an On-Screen Keyboard appears. This is not the Windows OSK, but rather the WinCC one. The functionality I am after should not allow unauthorized users, i.e. an operator, to use the Windows keys combination, but this should be available for the Supervisor. If the OSK is displayed for an unauthorized user, he can still press the combination ALT+TAB and possibly leave the application. I want to avoid that. Has anyone come accross this problem? Is there already a clean solution? Thanks! |

Hi Murof, yes, that's correct. I am using WinCC Professional SP1 Upd 9. Cheers! |
