Sony does not recommend installing Windows 10
Every new Windows OS release requires that computer manufacturers prepare new driver versions for the new OS in advance and that’s why the release date of the new OS is announced well before so that PC makers can prepare. While most companies have done just that, Sony hasn’t.
That’s why the Japanese company urges owners of Vaio notebooks not to upgrade to Windows 10 with the reason being very simple – Sony cannot provide new drivers as of now. What’s even worse is that you will have to wait – drivers for owners of Vaio notebooks with Windows 8.1 will appear in October of this year, while owners of Vaio computers with Windows 8 will have to wait until November. Things are much worse for users of Windows 7 – there isn’t a specified time period for drivers to become available.
Well, this is what you can easily call “bad customer support”.
