Whenever I right click on desktop the menu appears to be slow when compared to my previous C2D machine. So deleted "igfxcui" key from the Shell Context Menu which was located in HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers
Is there any issue due to the deletion in future use? It doesn't displays the Graphic Properties and Graphic Options now. My video card is ATI Radon which is a Hybrid Kind, is it culprit else? Do I need a reinstall else?
