As announced by Microsoft on June 1, Windows 10 - their latest operating system - is scheduled to launch on July 29.
Please refer to Microsoft website for details.
WARNING: There is a risk of software/driver corruption. We therefore strongly recommend that you do not upgrade to Windows 10 when it becomes available on July 29.
Sony is now testing Windows 10 and will be providing compatibility information after July 2015. The release schedule will vary according to the different products.
With regards to Sony VAIO personal computers, we are preparing a Windows 10 upgrade procedure - together with the necessary drivers and software* - for compatible models released after October 2012 (which were delivered with the Windows 8 or Windows 8.1 operating system preinstalled). Please note that Sony is currently not planning on providing an upgrade procedure, nor drivers and utilities, for older models which were released with Windows 7 or previous versions of Windows preinstalled.
Please wait until the upgrade information is released by Sony. Visit our support website regularly for the latest information and update about this topic.
*Note that some of the functions, utilities or other software on your computer might be missing or not working properly after the Windows 10 upgrade.
