No upgrade path from Windows Phone 7 to Windows Phone 8
Microsoft has unveiled its new Windows Phone 8 mobile operating system for smart phones. Several major changes have been introduced in Windows Phone 8.
The OS will be based on the NT kernel and will support multi-core processors. All Windows Phone apps that are currently there will also run on Windows Phone 8.
However, the existing Windows Phone 7 users won’t be able to upgrade to Windows Phone 8. They will have to install the Windows Phone 7.8 update. It will include some of the features of Windows Phone 8.
According to Microsoft officials, Windows Phone 8 requires different hardware specifications as compared to the older version of the OS. In other words, Windows Phone 8 is not backward compatible. But with the Windows Phone 7.8 update, users can enjoy the new interface of Windows Phone on their mobiles.
Windows Phone 8 and the desktop operating system Windows 8 will share the same kernel, file system, and apps. The two operating systems are scheduled to be officially launched in October or November 2012. On Monday, Microsoft had announced its Surface tablet with Windows 8.
