First you will have to create a short cut, for that on your desktop right click and select New from the popup menu. From the sub menu, click on the Shortcut option. This is relatively easy to do as it is almost the same method that was used in previous versions of Microsoft Windows.
Next you will be asked about the location of the item, for which type the address mentioned below:
Be sure to carefully put in all the characters without making any mistakes.
Give an appropriate name to the shortcut folder that you have created. Be sure to use a name that makes sense and that you can easily remember.
In the end click the finish button. This will complete the shortcut creation process.
When you open your folder which was created earlier, you will notice that all Metro apps are present in that folder. This will help you in selecting an app that you are looking for easily without any hassle. This is a great feature of Windows 8 as the folder is automatically populated with what you are looking for.
Just drag your cursor towards the desired app and double click it, in order to launch it. This is relatively easy and you will be familiar this step as it resembles previous versions of Windows.
