Thanks for the input Radouch. I'm not going to run a binary from a recent member as I don't have an isolated environment for testing right now, but perhaps that helps others.

I didn't manage to fix whatever issue is causing me grief with my regular Windows box, but I was able to compile the binaries on a freshly installed Win 10 VM. The binaries created on the Win 10 VM did work fine on my usual PC (Win 8.0). 

For anyone else that might want to test these, do understand that I'm a relative newbie at compilation (most of my experience is with cudaminer/ccminer), so I doubt I'd be able to fix any issues one might find. The following link has binaries from the current code on git, and were compiled using a clean/fresh Windows 10 x64 VM with VStudio 2015 and Boost 1.59.
Aeon-Win-x64-0.9.2.0-git.zip

@smooth:
I see my hashrate restored while solo mining on the daemon (about 640h/s now), so thank you, looks that the issue is fixed!
Side note, please update the OP with the revised compilation instructions as per the following post:
