I had the same problem with a recent update. I persisted (downloaded update several times) and finally got it to take, and thought well I'm finally past the Creator's update. Once the update took my puter was too unstable to run much of anything. So I tested for all kinds of non-Windows issues, like hardware, finally rolled Windows back to pre-creator's update and now the puter is much more stable and working well again.
My puter engineer son spoke with a friend (a couple weeks ago) who works for Microsoft; apparently they were having widespread stability issues with one of the updates. I'm holding off for now, just trying to let antivrus update. Hopefully by the time I update again Microsoft will have things ironed out.
