Hi, I was facing shutdown issues on Windows 10 Insider Preview (always latest versions).
I've got the long way to troubleshoot (sfc /scannow, dism, power troubleshooter from Microsoft, etc.).
Then I realize that I need to test the default Windows 10 buttons. All of them work: shutdown, restart, hibernate and sleep.
But when I use Classic Shell ones:
Sleep does not "turn off" the computer and does not keep only the blinking led. In other words, the notebook seems to be on (hot, fan...) but screen always black.
Hibernate does the same: computer does not turn off, power led kept on and computer seems to be on.
Restart was shutting down the notebook
When I turn off the "Hybrid mode" into Classic Shell settings, everything works again.
Weird is that the "hybrid mode" is enabled into Windows 10 power settings.
Hope it helps troubleshooting this...
