I didn't see where any of the tools would help me determine what happened August 2. I have not used my Jetpack since then. I did check all of my downloads and there was nothing large. I see no evidence that Windows 10 loaded. I did get a message asking me if I wanted to download it and I declined. I also just verified that I still have Windows 8.
I tried Glasswire, but it looks like it can only help with this point forward.
