Windows 8 is here and Microsoft is all set to deeply integrate the operating system with its other devices. Making the first move, the software giant released a Windows 8 companion app to keep its Windows Phone 8, Windows 8, and Windows RT devices in sync.

The Windows 8 companion app is currently available in the Microsoft App store, and the Redmond-based firm is expected to unveil Windows Phone 8 operating system in a few hours. The app provides a Zune-style user interface allowing users to copy photos, music and videos to another device or vice-versa.

In the description on Windows 8 store page, the app is listed as tool. System requirements include a version of Windows 8 running on x86, x64, or ARM processor architecture. Unfortunately, it will not support mobile devices running older versions of Windows Phone.

The full list of features of the companion app, as listed on Microsoft's website are as follows:

• Get your music, photos, and videos from your computer to your phone (and vice versa).
• Quickly share things from your phone with Windows 8 apps (like Photos, or Search). You don't even have to open the Windows Phone app to move things around.
• Automatically save photos and videos you take with your phone to your PC.
• See at a glance how much space you're using for each type of content, so it's easy to make sure you never run out of room on your phone.
• Get to WindowsPhone.com to download apps, learn more about your phone, or find it if it's lost.

Microsoft promises predicted features with the app; however, the Windows Phone 8 devices are not available at the moment to test the functionality.

The Windows Phone 8 launch event is due to kick off in San Francisco later on Monday Oct. 29. However, Microsoft revealed the new features of its upcoming mobile operating system earlier this year.

Windows Phone 8 will land with stunning features including multi-core processor support, support for HD screen resolution and microSD memory cards, Near Field Communication (NFC), Wallet app, and a number of upgrades to core Windows Phone applications.
