Get App History on Windows 8

This article shows how to determine what your Windows 8 or Windows 8.1 app has been doing.

Windows 8 and 8.1 is now a very smart operating system. It keeps track of apps for you and shuts most of them down when you don't use them. But some of the apps still run in the background and get data and updates regularly.

Do you want to determine what your app has been doing on your Windows 8 or Windows 8.1?
The new Windows 8/8.1 Task Manager has a new tab called App History. That shows all the app history and updates of their recent activity. It also shows when the last time tiles were updated of an app.
To launch the Task Manager, hit CTRL+ALT+DEL and select Task Manager form the list.
You will see Task Manager launched.
Click on the "App history" tab where you see name of the app, CPU time, Network activity and tile updates.
