Make the most of your time with the new Windows 10 update

With Windows 10, we’ve focused on delivering the most modern and most secure operating system. Since its initial launch, we delivered two updates with features designed to enable the creator in each of us. With our latest major release – the Windows 10 April 2018 Update – we want to give you back some of your greatest currency, your time. Our hope is that you’ll have more time to do what matters most to you –  create, play, work or simply do what you love.
