I am getting an error on updating to TH1 Professional 10240. I am not able to find any details about the error that I am getting it. I am doing this on my laptop. I am already using 10166 and that does not give any issue. But when I went ahead with TH1 Professional 10240 update I am getting this problem.

My system is no longer stable and performing well. I want some help here to resolve the issue. I had tried checking out but I cannot find any better solution for the same. What should I do to revert the old status back if this new update is not stable?
