Good news for Surface Pro 2 and Surface Pro 3 owners running Windows 10 Technical Preview, there is a new video driver available from Microsoft that will improve the stability of the OS. The update is available via Windows Update and is a new Intel graphics driver for the Surface Pro that should resolve the issues. I have a new Surface Pro 3 and while its shiny and new I am holding off putting Windows 10 on it but I am not sure how long I will be able to resist.
#WindowsInsiders using Surface Pros with 9926: there is a new graphics driver on WU that should improve stability for you.
