Bluestacks is a free software that allows you to use your favorite Android apps on a Windows PC or Mac. You can download apps like Angry Birds Space, 2go, Whatsapp or BBM to Go directly into Bluestacks, or sync the apps from your phone using the Bluestacks Cloud Connect Android app.
Using Bluestacks is similar to using an Android tablet: It works a bit like a widget. When clicked, the BlueStacks App Player will display the ten apps that have already been pre-installed and application suggestions which can be installed using Google Play Store. You can install more application by clicking on More below the big + sign. Bluestacks can be viewed in minimized or full screen.
Please note that Bluestacks is currently in beta stage: Beta or prerelease software is not intended for inexperienced users, as the software may contain bugs or may potentially damage your system. I strongly recommend that users exercise caution and save all mission-critical data before installing or using this software.
I have personally tried this software on Windows XP, Windows 7 & Windows 8, the performance is great and it is worth trying!
