In Windows 8 - Bypass Windows’ Default App Choices

Some of the new apps built directly into Windows 8’s Metro UI are less than pleasing when it comes to actual usability – here’s looking at you, Video app. But it’s equally frustrating to have to use an “open with this app” command whenever you want to pull up a new file format.
Our solution? Edit your file-opening preferences in one big batch. Type “default programs” within Windows 8’s Metro UI and click on the corresponding link that appears. Select “Set your default programs” and have at it – each program will tell you how many extensions it can open versus how many it is opening, just to give you a sense of your batch-processing power.
