If you've ever searched a computer's apps or settings, you know how frustrating it can be to guess the keywords you'll need to get a result -- why can't you just say what you want and let the PC figure it out? Microsoft must have asked itself that same question, as it's rolling out an update to Windows 8.1 that introduces natural language searches for common tasks. You only have to phrase your statement in a way that a human could understand to get useful links. Gripe that "my screen is too bright," for example, and you'll get a shortcut to the display settings. The new search feature won't help you find everything you'd want, but it could save you precious time when it reaches Windows systems this week.
