Tried this today, there is a ton of stuff in that file and I have no understanding of it at all, I think it is all past updates and so I guess it would be ok to delete all of it. I did delete all of the updates in 2018. I'm afraid it might be too late as this morning when I looked I had restart options without the update. I'm afraid the box may have updated over night. is there a way to tell if you have the update that you don't want.
