Fix RTX graphics card shows black screen on client
Issue: Black screen on client which has RTX graphics cards
RTX Graphics cards use new drivers released from NVidia, which have some issues with Windows 10 1803 and any older build for it.
To fix the black screen problem, you need to use Windows 10 build 1809 and the Latest NVidia drivers.
Note: if your current image is an older build, then you need to make a new image for it.
Do not try to upgrade the OS from older build to newer build of Windows 10, as it removes all NIC drivers and CCBoot client applications from the OS and breaks the diskless booting capabilities on that image.
