Or in other words, both teams Office and Windows did align.
Here is what to do:
If you can disable Windows Sniping Tool
Group Policy follow the screen shot
Than or change your Hot Key :
HEX 83 is the default Key WIN+SHIFT+S
and or you might fully disable the Global Windows Hot Key WIN+S
reg.exe add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v DisabledHotkeys /t REG_SZ /d S /f
Reboote your computer
now it should work as usual and you can work proper with OneNote again.
