I don't know. I only relayed the info available on the companies' web sites. The main thing to take from it is that the .NET Preview should be avoided if not already installed and uninstalled if it is installed.
KB4088875 seems to have been pulled from windows update, as my win 7 and server 2008 r2 machines are not finding it. its still available on catalog though. -andy-
I can confirm the issue, actuallyI only get KB4075211 first, then when installed, restarted and researched only KB4091290 and finally KB4088875.
yes i noticed that few days ago by trying to integrate that update using Simplix Pack, in fact, it can't be integrated but it is still executed by RunOnce during the install so people might think that it can be integrated but it's not the case.
