I would like to prevent them from even coming up if possible. I don't know why Windows doesn't use the %system root%\temp folder for these. :(
Looks like there have been a couple others asking about the same issue but the answer is just take ownership and delete, which would be fine if it were just 1 or 2 stations but I'm looking at possibly hundreds of them. Would there be a way to script a removal of these and force Windows into using the Temp folder?
Similar issue, How do I delete left-over Windows Update folders?
