Most likely you just hit a semi-malicious web page or got redirected to one. The "messages" you might see vary alot and could look like anything from a BSOD screen to a more Microsoft inspired look always with a 1-800 number to call.
As far as I can tell the logs look ok as far as malware goes. Not really that familiar with W10 logs yet.
I would imagine being on the insiders release cycle is like getting a beta version everytime. I assume you get builds before the final release? Things may not work like they normally might.
