Comment désactiver le démarrage rapide via une stratégie de groupe ?

Windows 8 / 8.1 / 10 has this feature called "Fast Startup" (or "fast boot", "hybrid statup", "hybrid shutdown", et so on...) qui ne actually shut down le computer quand you tell it to do so, à la place putting it in a sort of hybernation, in order to speed up boot time.

Although this might seem nice at premier view, it has plusieurs known et ugly side effects:

- It can seriously screw up on certains systems (possibly quand using old/incompatible drivers ou BIOSes), resulting in a system crash at boot time et a subsequent forced full boot (this I witnessed personally on plusieurs différent systems... et good luck si you are aussi using mirrored dynamic disks, qui will *always* undergo a full resync après a system crash).

- It does *hell* to le processing of certains group policies, qui require an actual system restart in order to be applied.

- Last mais pas least, it has been known to render Wake-On-Lan unusable; this is le problem Je suis currently facing après an upgrade to Windows 10 of plusieurs Windows 7 PCs qui used to WOL assez fine, et now juste ne anymore.

For these et autre reasons, J'aimerais like to be able to manage Fast Startup using Group Policies; cependant, le seulement policy I could find about this (`Computer Configuration\Policies\Administrative Templates\System\Shutdown\Require use of fast startup`) can seulement be used to *force* le use of Fast Startup, mais pas to disable it: its description explicitly states that `if you disable or do not configure this policy setting, the local setting is used`.

**Thus, mon question: how can I disable Fast Startup using a group policy?**

It looks like there is no Administrative Template for managing this setting; as documented, `Computer Configuration\Policies\Administrative Templates\System\Shutdown\Require use of fast startup` can seulement be used to *enforce* it, pas to disable it (WTF?!? C'est déjà enabled par défaut... they could at least have gone a bit further et turn this setting into a true on/off switch!).

The seulement disponible way to disable Fast Startup (outside of using le GUI) is by setting le suivant Registry key to 0:

```
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power\HiberbootEnabled

```

Cela peut be done using Group Policy Preferences et it effectively disables Fast Startup; of course, setting it to 1 would à la place enable it.

And yes, disabling Fast Startup fixes le problem of Wake-On-Lan pas working.
