" tap the Windows key, start typing 'Exce...' and then click on the Excel icon ('tile') when Search finds it"
...and as I'm getting tired of pointing out, it doesn't work very well. It only seems to search Metro's private startmenu folders - if the app's not in there it won't be found. Which means more than half the useful apps and links with parameters on my system just aren't visible. Despite the fact I can see them on my desktop and in the classic start menu!
Without wasting an afternoon manually adding links direct to the underlying folders (something beginners won't even know about) they'll stay hidden from the search. Some of use prefer to keep some apps away from OS partitions we might need to reformat, reinstall, or want to share them with another OS.
It's no substitute for a real, user configurable setup process even beginners can understand. With Metro, you take what MS offer, do without or get hacking, the whole experience stinks of it.
