Showing Sub Menu Faster

As you know, Start menu has so many sub menu inside it. To expand them you must move over your mouse cursor to the menu or click to make it faster. And I think if you have to click it one by one to expands every sub menu that will opened, usually we will just expands it by move our cursor over the menu but if we're using this way it will delayed and if you felt that's so slow to expanding the sub menu, just make it faster..

To adjust the delay value you have to modify it via registry. The delay time that configured by Microsoft is 400 miliseconds. That's mean you must wait for 400 miliseconds for expanding the sub menu when your cursor over the menu.
OK, open your Registry Editor first, by click Start - Run menu, type regedit in textbox then hit Enter. In Registry Editor, drive your cursor to HKEY_CURRENT_USER | Control Panel | Desktop then look for MenuShowDelay entry. To modify its value, double click it then type your own value then click OK button. I prefer to set it to 100-150 because if you adjust it too small, your system will works too hard, specially the hard drive. So, try it by yourself until you find the 'comfort' value.
