Call Microsoft. They are very well aware of the issues (I spent a long time on hold though until I spoke to someone). Google their help number on here. Put the kettle on and wait. Try to be patient, because the agents who you talk to didn't cause the problems, but they're taking the flack for it. One alluded to me (a manager) that at least one of the developers who signed off the update for release would likely be fired.
The latest update (build 1803) works with some comps and not others depending on the build already installed (1603 too old, as mine had) or 1703, 1709, those two are okay) AND BIOS update (from the comp manufacturer) none of which MS tell you the comp should have first before the latest update. That is the screw up. They make too many assumptions.
Call them. You might get lucky.
