An easy way to keep track of videos on your computer is to use the Videos library. By default, the Videos library shows all the videos located in the My Videos folder, but you can include other folders in your Videos library, too. For more information, see Include folders in a library.
To watch videos in Windows, you need a program designed for playing video files. If your computer didn’t come with such a program, you'll need to install one before you can watch videos on your computer.
Open the Videos library by clicking the Start button , clicking your user name, and then double-clicking Videos.
Open a video in the default program for the file type
Double-click the video file.
Open a video in a different program
Right-click the video, point to Open with, and then click the program that you want to use.
Arrange videos by year, rating, or another property
In the library pane (above the file list), click an item in the Arrange by list.
In the Arrange by list, click Clear changes.
Find a video by file name or property
In the search box, type the file name or property. You can type the entire name, or just the first few letters.
For information about adding properties to a file, see Change the properties for a file.
Return to the Videos library after searching
Find a video by length
Click in the search box, click Length, and then click a length range to view all videos in that range.
Find a video by the date it was created
Click in the search box, click Date created, and then click a date or date range.
Find a video by file type
Click in the search box, click Type, and then click a file type.
You can change the items that appear in your Videos library by including folders. This is convenient if you store some video files in a location other than the My Videos or Public Videos folders.
In the library pane (above the file list), next to Includes, click Locations.
In the Videos Library Locations dialog box, click Add.
Click the folder or drive containing video files, click Include folder, and then click OK.
