Charm Bar

Windows 8 operating system has a new feature known as Charm Bar using which user gets access to various operating system functions / charms like Search, Share, Start, Devices, and Settings .

This feature is available across all the screens in Windows 8 including ‘Desktop’ app.

The five charms

Search, Share, Start, Devices, and Settings are always available on the Charm Bar.

Lets understand the functionality of each of these charms.

  1. Search

    As the name suggests, this charm allows user to search for anything including apps, files, folder, settings. This is a context sensitive charm i.e. it performs intelligent search depending on the active application. For example, if the active application is ‘Start Screen’, it searches for files, apps etc. If the active application is ‘Mail’, it searches for specific messages in Mail.

  2. Share

    It allows user to share the information from one application to other applications or with someone else. For example, user can easily share photos with other users using ‘Mail’ or ‘Facebook’ App. Similar to Search charm, this charm is also context sensitive. For example, if the active application is ‘Start Screen’ user don’t have anything to share with other apps or users, however if the active application is ‘Weather’, user can share weather information using this charm.

  4. Devices

    This charm allows you to connect to all the external devices connected to your PC, including both wired and wireless. This is particularly useful if you want to share the information on network PC or if you want to print a document.
