For the vast majority of users out there, upgrading to Windows 10 has been a relatively smooth process regardless of what hardware you're using. But for Sony Vaio owners, Sony is advising users not to upgrade to Windows 10 just yet as the company isn't even close to having drivers ready.

Over on the Sony Vaio support website, a large warning advises people to hold off on upgrading to Windows 10 until the company has compatible drivers available. For users who bought systems with Windows 8.1 or 8 pre-installed, these drivers won't be available until October or November respectively.

At least three months is quite a long time to wait to upgrade to Windows 10, especially considering those with devices from competitors have been able to upgrade from day one. Acer, Dell, Lenovo, HP and Asus are just some of the companies that are already providing Windows 10-ready drivers for their laptops, and many provide step-by-step instructions guiding users through the upgrade process.

While owners of some Vaio laptops previously running Windows 8 or 8.1 will eventually get drivers supporting Windows 10, those that purchased laptops running Windows 7 out of the box are out of luck. Sony doesn't provide any information on when these devices will receive drivers or upgrade instructions, which indicates Sony will not continue to support them into the Windows 10 era.

Sony's lackluster support for Windows 10 is disappointing, but not hugely surprising considering the company sold off their entire PC division to Japan Industrial Partners in early 2014. It's unlikely that Sony will continue to support their devices for much longer, so it might be time to look for an upgrade in the near future.
