I have reserved Windows 10 for my Sony Vaio laptop running Windows 8.1. I understand that after 29 July it will download to my machine and I will be given the option to upgrade immediately or do so at a later date. I have today received a notification from Sony advising me not to upgrade to Windows 10 until the drivers are ready as below Microsoft is offering a free upgrade* to Windows 10. • The offer applies for qualified Windows devices which are upgraded during the first year*.

Although Microsoft is offering the Windows 10 upgrade, it is strongly recommended that you wait to install it until the drivers & installation instructions are available for your VAIO PC. My question is do I need to cancel my reservation for Windows 10 completely. Dell Vostro Drivers For Windows 10.
