One of the first things that was noted during the upgrade progress was that the system was still functioning, somewhat.
With that said, there may be cases where a system needs to be accessed without resorting to a backup restore point.

There are many causes, and probably the first version to troubleshoot with is by uninstalling your video card drivers and updating with the newest version from Intel, AMD or NVIDIA. One major point of this is that we used both AMD and NVIDIA video cards for this system so it is not necessarily driver related. One common issue was having a black screen and white cursor after passing the login screen in Windows 8.1. As the Windows 8.1 update was released, we saw many users upgrade directly from the Microsoft Store.
