delphi - How to replace or block Windows Taskbar and Desktop for security reasons, programatically? -

like cyber coffee applications disables user ability use other application ones started inside cyber admin application panel, searched internet way of doing in delphi:

• remove windows task bar;
• disable alt+tab function;
• disable task manager;
• be able do/undo changes in configuration panel.

these needs keeping users downloading viruses , making changes windows configuration or play games, if system administrator's preference. the own program serve container authorized applications run inside if mdi application. working

of course system manager have options disable or revert.

is there way make 4 configurations in run-time delphi xe3?

i'm not familiar delphi. i'm not sure if possible during run-time. following:

1. write registry prevent alt-tab see this.
2. again write registry disable task manager see this.
3. sounds can disable task bar registry see this.
4. on control panel have options , when hit save, save , restart computer.

this provided delphi can write registry (i believe c# , c++ can). if not, create .reg files , execute calling cmd.exe arguments. think cause pop-ups though.

update: may able load in registry changes without signing out killing explorer.exe , loading again. may load parts of updated registry though.
