Command to display my computer on desktop

Right click on Task bar (bar on bottom of windows) > Properties>Start menu > Select Classic Start menu>Apply>OK.

You will see my computer icon in desktop.

If you are not getting,

Right click on desktop > Desktop>Customize Desktop>Select the icons to be shown in desk top.

Hope this helps

Thanks for the quick answer?

However is it possible to have a little .exe file or a batch file wich when double clicking on it it automatically changes this settings.

Thanks
