I ran an update to windows 10 (I got a message box to schedule the update) and now boot gets my home page but when I log in I get a black screen. I have been through many of the "fixes" on line, even going to SAFE MODE, but when I get to the point where I can take action, the cursor disappears and the keyboard does not work. Online, folks speak of having the same problem after an update, but their fixes do not work. Have you seen this issue? Know of a fix?
