I have an issue with the "Credential Manager". This allows someone to click a box and then anyone using that computer with or without approval has access to the level that the original user has. In larger companies we cannot police computers at that level each day to see if someone has selected that box. This created a recent problem where a employee used a computer on a day the owner was out to access information they had no right to.
To me this is a serious security problem that needs a fix. Something like our abilities to modify menus to eliminate or include desired commands.
