You may notice in Windows 8 the Startup Folder is hidden by default, to get it back so that you can have applications or documents automatically run when Windows starts up:
1. Right-click a blank area of the Start Screen then click All apps.
2. Click Run.
3. Enter shell:startup in the Run Dialog that appears and click OK.
4. The Startup folder will appear.
You may put shortcuts of programs and documents you want loaded on startup into the folder.
