Q. Just now I ended up with a blue screen (BSoD) “UNEXPECTED STORE EXCEPTION” with a :(. and restarted by updating to 100% in few seconds.

Lenovo Yoga 2 Pro upgraded from Windows 8.1 to Windows 10 couple of days ago!

I do use my laptop for 5 to 8 hours in a day.

Is this happened to you? Why did it happen? How to fix it?


There were three McAfee drivers showing up on the “raw stack” such as:

So there is a good chance McAfee is causing the crash.

I would suggest to uninstall, at least temporarily, McAfee and use Windows 10 built-in antivirus (Windows Defender) and firewall and see if the error resolves.
