This should make it easier to find the app you want. My favourite method is pressing Ctrl +Shift +Esc, alternatively type ‘Task Manager’ at the Metro-style UI. You can now search your apps which can be listed in alphabetical order, or grouped by category, most used or date of installation. If you want to close a Windows 8 app and all else has failed, then launch Microsoft’s built-in Task Manager. Click on the small downward facing arrow icon on the bottom left which will take you to the All Apps. Another way to find the apps you need is to just have Windows 8 show you the complete list of apps on your computer. Some of you may not like this system of desktop search, but it is the route that Microsoft has taken in recent years. The default for the new desktop search is for it to mainly show you apps, but you are able to set up the filter settings to also start showing you settings and even files.

When you begin typing a search in the desktop search bar then the results will show Apps and Programs that correspond with the letters you are typing. When you begin to type out a Windows 8 Search the results will appear on the left. Alternately, you can hold down the Option key and select File > Close All in the menu bar at the top of the screen. When you are on the desktop you can simply hit the WINKEY or even CTRL+ESC and you just start typing in what you need Windows 8 Search to find. To get rid of all of them quickly, press Option+Command+W on your keyboard. The Windows 8 Search will work almost identically to the Windows 7 Start Menu Search.
