Try using a System Restore point. In future always make it best practice to set a restore point or make a system image before attempting anything like this.

Hy ,i'm new and i would like to add two words even if the theme was resolt. I use to patch many themes on win7 that i install and all finish into a directory : "C:\Windows\resources\Themes".If you go there you could find all the theme including the normal aero and just by clicking a choice theme you can restore it.You could also play by choising different themes.By
