was cruising my computer and found Vulkan Run Time Libraries in my programs.
I had never seen this before and I didn't think I installed it so I looked it up on the web.
It seems it's a Nvidia update for my Graphics card and was installed during my Nvidia Updates so I guess I did install it.
Anyway ,here's a conversation about it in the Microsoft Community Forum .
I'm posting this in case others find this on their computer and wonder what it is.
