Windows Explorer Search

On Windows 7 (and I guess Vista too) whenever you make a search for a file in Windows Explorer (top right box of the window) the input you used to search for a file gets stored. The only way I can see to currently delete these entries is by putting the mouse over each one and pressing the delete key. Surely their must be a better way of doing this, could CCleaner automatically remove these entries for people as it would be cleaning up some stuff privacy wise which everyone on Windows 7 will have to deal with.

I figure its a no brainer to add Windows Explorer Search as a cleaning option and I'm sure im not alone on this ^_^

Thanks.

After a few days its now starting to show up via google on how to clear this info and its rather simple to do. Simply deleting the following registry key will clear the list, hopefully this can now be added to CCleaner as a default option.
