One of the really nice things in Windows 7 (and Windows Vista) is the way that the search box works on the start menu: that is, open the start menu, type stuff until you get what you need, hit enter...
It's stopped working properly on my principal box.
If I type a file path (for example,
c:\data\) it works exactly as you'd expect, listing matching folders.
If I type an application name (for example, Excel), instead of the link to Excel appearing, I get a blank icon and "Programs". Similarly for files I know to have been previously indexed/remembered by the system and indeed anything that isn't a file. The most obvious other "broken" elements are URLs - normally if one types
http://superuser.com then hitting Enter will launch the browser. Now I get nothing (hitting Enter has no effect).
I'm at a complete loss here as to where even to begin to look to sort this out (which is scary, because I'm supposed to know what I'm doing).
