Start Menu Modify - Pinned Item Starting

The improvement which I'd like to suggest is to change the behaviour of the recently used programs part of the Start Menu so that it doesn't include any programs which are already pinned. I have several programs pinned because I use them so often - Word, Excel, Outlook Express etc - so it's pointless and irritating to have them appear twice on the menu because they are on the recent programs list under the pinned list too. This is even more irritating when, as occasionally happens, it is a program which has a unique initial
letter which I use to quickly start the program. For example on my Start Menu, Notepad is the only pinned item starting with N, and so I can press "Start, N" to run it. Unfortunately sometimes Notepad ends up in the recently used list, and then because there are two programs beginning with N, my shortcut no longer works.

One point worth noting perhaps, seeing as I've just tried this and it didn't seem to happen ... it only happens at bootup, if you do anything to modify the Start Menu - such as pinning a different item - then all duplicates get removed. And they won't reappear if you use the program again. However as soon as you do a restart, they reappear in the menu, and stay until they are forcibly removed, such as by pinning something else.
