Run Android Apps on Windows 7
BlueStacks has just released a software player (BlueStacks App Player) that allows Windows 7 users to run Android apps within the Windows environment. It is available for free and has some pre-loaded apps. You may encounter some problems installing it on older netbooks or tablets but it should perfectly install and run on any decent x86 Windows system. In addition, starting with Windows 8 release you would be able to run Android apps on ARM architectures as well.
With the BlueStacks Cloud Connect app feature users can sync apps between their Android devices and Windows. BlueStacks enables Android applications to run on Windows machines and its technology can be integrated into offerings for both the consumer and commercial (enterprise) market segments.
