This pretty much qualified as an unusable system in my opinion. By "no longer worked" I mean either the application or device would no longer execute at all or an attempt would generate an error message about missing DLLs which were not missing. After spending an entire very long day trying futilely to correct these problems, I decided it was much better to cut my losses and roll back to the original Windows 10 release. Thereupon everything worked as it had done, and I could get on with life.
A quick search revealed that there are hundreds of problems with Windows 10 build 1511. As I said in my original post, the affected system was fortunately not the one I use for astronomy. Had it been, I might have mistakenly thought the problems were hardware related.
From what I have read and from what I experienced, Windows 10 1511 is very far from being ready for prime time. I am happy for those that have upgraded without problems. But, I will not voluntarily upgrade any more systems to 1511.
