Clearing the RUNAS domain\username dropdown

Good Day:

When you right click on a shortcut/object, and select RunAs, then select "Run as the following user ", there is a dropdown box that allows you to put your domain\username in there.

My current list is full of OLD information and I need to clear it out so I can populate it with the current information.

I cannot seem to find where/how this is done.

Any one have any ideas?

 

Never messed with this one however I think that if you search through registry you might find them.

Click on START>RUN and type regedit

Then try to FIND the keys and delete them. I would export the registry before doing anything just in case.
