On the Start menu, you can sort the All Programs menu. Windows XP sometimes adds new shortcuts to the bottom of the All Programs menu when you expect them to appear in alphabetical order. In either case, finding the program you want to run is difficult when the sort order of the Start menu gets out of hand.
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MenuOrder contains the sort order of the Favorites menu and Start menu. The subkey Favorites contains the sort order of the Favorites menu. The subkey Start Menu contains the sort order of the classic Start menu, and the subkey Start Menu2 contains the sort order of the new Start menu.
Deciphering the contents of these three keys is next to ridiculous, but you can remove any of them to resort the corresponding menu in alphabetical order. For example, to restore the All Programs menu to alphabetical order, remove the subkey Start Menu2. To remove a subkey:
In the left pane, right-click the subkey you want to remove, and then click Delete.
To restore the Favorites menu in both Windows Explorer and Internet Explorer, remove the subkey Favorites. I typically remove MenuOrder to resort all of the menus at the same time.
