I am shifting to Windows 8.1 from Windows 8 so I have to reinstall Bluestacks. Will I lose all my WhatsApp and Viber and WeChat contacts? How can I save my contacts and chat history so I can add it again after I reinstall my new Windows?
There is an easy way to fix this. Go to C:\ProgramData\Bluestacks\UserData. Copy the entire folder to another partition then install Windows again. At the end of the installation, copy the folder back to its location and start Bluestacks and all your apps, contacts and settings will be as they were in Windows 8. If you do the Upgrade, the application will be preserved.
Thanks Julia :) by entire folder you mean the entire Bluestacks folder or just the userdata folder?
