Whenever a new operating system is launched, there are numerous hidden features that one might not immediately discover. One such option in Windows 8 is to organize different Metro applications within groups on the Metro Start Screen. Creating groups can help you better organize your convoluted Metro Apps to identify them at a glance. While applications on the Metro Start Screen (known as Tiles) are auto arranged, you can give a name to Tile stacks to create separate groups for better organizing applications. This might be especially required when you install new applications in Windows 8 which might clutter the Start Screen.
To get started access the Metro Start Screen (e.g. by clicking the Windows key) or via the Charms Bar. The Metro Start Screen also appears when Windows 8 is logged in, unless you have disabled the Metro UI. To create groups for the Metro UI, scroll the screen towards the right-hand side until you see the minus sign (-).
This will provide you with a birds eye view of the Metro Start Screen. Simply right click on a Metro App (stack) to reveal the New Group option and click on it.
Once you right-click on a Metro App Tile stack, you will be provided with the option to organize apps by entering a name. Simply enter a name (e.g. Multimedia Apps) and click on the Name option.
This will give a name to the selected group of tiles (where the selected app stack was present). In case you would like to organize specific apps in separate groups, you can simply drag and drop tiles to organize your Start Screen. As you can see from the image given below, you can enter specific names after organizing tiles (after drag and drop) so that you can create groups that can better organize your apps.
