Erm, please get your facts straight before you start throwing around accusations. I am an Insider Previewer using the Release Preview option only and I got the cumulative and other updates on Thursday through the Windows Update as normal. I initially thought the tile issue was due to the cumulative update and reported it via the Feedback tool. However, it turns out that the issue is due to the latest driver; there are now numerous reports of it on the forums and NVIDIA have already confirmed this. They are going to release a hotfix driver soon.
