How to revert back to my Default Shell in Windows 7(64 bit)

i have installed a new desktop customization tool in my laptop running Windows 7.
the default shell got replaced,and now i can't see the start menu, my wallpaper isn't there,the right click on desktop doesn't work,all in all i am stuck.

now i want to revert back to the default windows shell,i don't want to format my computer because i have so many softwares installed.

i need help in this regard,please help me,i am really stuck.

pushing the 'windows' key should bring up the start menu--which should allow access to the control panel--then remove the 'customization' software.

Do this tutorial SFC /SCANNOW Command - System File Checker it will not harm any data or programs you have installed it will try to find and repair any corrupt system files that you have.
