Apparently, in Windows 10 doing a SHUTDOWN from the Windows Start Menu, in reality performs a hybrid shutdown instead of a full shutdown! This sometimes seems to create problems when running Windows 10 in a Parallels Virtual Machine.
Where can I activate a setting for doing a FULL shutdown each time I shutdown from the Windows Start Menu?
Disable "fast start-up" under:
Control Panel > Power Options > "Change what the power buttons do"
If you always use the start menu, you can also hold shift while clicking the power icon and then "Shutdown".
To quote Microsoft:
The Fast Startup feature in Windows 10 allows your computer start up faster after a shutdown. When you shut down your computer, Fast Startup will put your computer into a hibernation state instead of a full shutdown. Fast Startup is enabled by default if your computer is capable of hibernation.
Fast Startup results in a "Hybrid Shutdown", where system/kernel level processes are hibernated, but user level programs are closed as normal. This creates the illusion of a full shutdown, but enables the system to be ready for use faster.
all running programs are saved in their current state and then resume. Strictly speaking this is not the case with a hybrid shutdown, windows still closes all user-level programs. Only kernel-level and similar programs are hibernated, which reduces boot time. This is true with a windows "hibernation", which you can perform manually.

You can also disable the fast startup through the Registry:
in HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power key set
HiberbootEnabled value to 0 (type REG_DWORD).
This method is useful in corporate environment if you need to do it on many machines.
Setting the value to 1 enables fast startup.
