If you don't have a desktop shortcut to any Office 2013 products on your desktop you may need to access these programs from the start menu. Select Start and choose All Programs and browse to Microsoft Office 2013. Here you can launch any Office 2013 application installed on your computer (Word, Excel, Outlook,...)
Creating a Desktop Shortcut
Open the program menu to show the item you wish to have a shortcut for. Right click the item and select "send to" then "Desktop (Create a shortcut)"
Windows 10 utilizes a slightly different start menu than Windows 7. In Windows 10, you rather than creating shortcuts to your desktop, you can pin them to the "metro" screen section of the start menu. This allows for quick access without cluttering the desktop.
Click "ALL APPS" to view a full list of programs on your computer.
Pinning a Program to the Metro Screen
By right clicking on a program in the "ALL APPS" list, you can choose to pin the program shortcut to the metro screen (those tiles on the right hand side of my menu) or to the taskbar (the section along the bottom of the screen). This allows for quick access without unnecessary messiness of the desktop.
