I am not getting my desktop

Hi
I have just upgraded to 10 and successfully installed it but now facing one problem. my computer is not showing desktop on the screen. when i click on start menu it shows tiles but when i right click nothing is shown in the desktop. I have not been able to access my computer, recycle bin etc. on the screen. Infact i tried many things like right clicking and try to find out the option where it allows one to hide or show the desktop icon but no success. When i right click on the screen i mam not geeting any option. I cannot minimize or maximize the window.
I have also done CFC, enabling XAML start menu in registery but still no result.
plz help
