06. Adobe Photoshop Express
It's a little basic at the moment, but at least Adobe has got its foot in the Windows 8 door with the free Photoshop Express app - you can easily crop pictures, adjust brightness, contrast and colours via on-screen sliders, and add a range of instant filtered looks to your photos.
Everything is mapped out to make the most of a full-screen touch-enabled interface, though the reduce noise tool is a paid-for upgrade, which is a shame. You can import pictures from disc or sync them over the web.
Not only does the Windows 8 Google Search app enable you to type (or speak) your queries, it includes a rudimentary web browser to enable you to see the results within the app, as well as access other Google tools such as Gmail and Maps.
08. Google Search
Like many Start screen apps, it suffers from too much blank space, but it's an intuitive tool that will be of particular interest if you're heavily invested in the Google ecosystem (you can easily call up your Google search history, for example).
