These are actually just regular updates to fix bugs in the .NET July Updates. I did not come across them from my regular sources, so good catching! I'll be adding them to the repository.
These are just the Security and Quality Rollups of July 2018, and those are always superseeded by the newest ones available (in this case, the August ones, which I already have in the repository).
Thank you so much. Just having people using the repo is enough motivation to keep it updated from month to month. If this makes it easier for people to stay on anything that is not W10, it's a victory
