Hi Ashi,
Thank you for upgrading to Windows 8. I see that you want to know where some of the basic applications are.
To show all apps,
1.You can press the Windows key to bring up the Start screen and then just type the name of the program you want to use.
2.You can also right click while on the Start screen and select "All Apps" on the bottom pane to show all the apps.
You can use this article to get to know Windows 8 better.
