New CMD switches for shutdown.exe in Windows 8 - Includes /hybrid but not /full

[HappyAndyK]

MSDN says that Windows 8 introduces a new /full switch on shutdown.exe, which performs a full shutdown of Windows 8 computer.

You can use the new /full switch on shutdown.exe. From a cmd prompt, run: shutdown /s /full / t 0 to invoke an immediate full shutdown

But if you use it (or even the corrected shutdown /s /full /t 0 - after removing the space before t) it does not work.

Now if you type shutdown /? in an elevated command prompt, you don't see /full as an available switch... you see only the following switches or parameters for shutdown.exe:



Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.

C:\Windows\system32>shutdown /?
Usage: shutdown [/i | /l | /s | /r | /g | /a | /p | /h | /e | /o] [/hybrid] [/f]

[/m \\computer][/t xxx][/d [p|u:]xx:yy [/c "comment"]]

No args - Display help. This is the same as typing /?.
/? - Display help. This is the same as not typing any options.
/i - Display the graphical user interface (GUI).
This must be the first option.
/l - Log off. This cannot be used with /m or /d options.
/s - Shutdown the computer.
/r - Full shutdown and restart the computer.
/g - Full shutdown and restart the computer. After the system is
rebooted, restart any registered applications.
/a - Abort a system shutdown. This can only be used during the time-out period.
/p - Turn off the local computer with no time-out or warning. Can be used with /d and /f options.
/h - Hibernate the local computer. Can be used with the /f option.
/hybrid - Performs a shutdown of the computer and prepares it for fast startup. Must be used with /s option.
/e - Document the reason for an unexpected shutdown of a computer.
/o - Go to the advanced boot options menu and restart the computer. Must be used with /r option.
/m \\computer Specify the target computer.
/t xxx - Set the time-out period before shutdown to xxx seconds.
The valid range is 0-315360000 (10 years), with a default of 30.
If the timeout period is greater than 0, the /f parameter is
implied.
/c "comment" - Comment on the reason for the restart or shutdown.
Maximum of 512 characters allowed.
/f - Force running applications to close without forewarning users.
The /f parameter is implied when a value greater than 0 is
specified for the /t parameter.
/d [p|u:]xx:yy - Provide the reason for the restart or shutdown.
p indicates that the restart or shutdown is planned.
u indicates that the reason is user defined.
If neither p nor u is specified the restart or shutdown is
unplanned.
xx is the major reason number (positive integer less than 256).
yy is the minor reason number (positive integer less than 65536).

There is no /full mentioned.

But I do see some new switches like:

/r - Full shutdown and restart
/g - Full shutdown and restart, followed by restart of registered applications
/hybrid - Shutdown of computer and prepares it for fast startup
/o - Go to the advanced boot options menu

So does this mean that the following will fully shutdown the Windows 8 computer:
/s Shutdown the computer

The correct syntax thus for a full shutdown of Windows 8 should be: shutdown /s /f /t 0
And for Hybrid shutdown should be: shutdown /s /hybrid /t 0

Is my understanding correct, or am I wrong? :|

Did things change in Windows 8 RTM? Or did the said MSDN post err!?

That post was from over a year ago. Maybe they pulled the functionality from the command?

One way to check is if you still have a running VM or machine running the developer preview. I know a lot of stuff has changed since then (some stuff added, other stuff removed).

I don't think I have a machine still running the DP to check. I don't even think I kept the install media for it, either...

Yes, even I see the same screen and the command fails to perform a full shutdown for my Windows 8 computer. Fully contradicts the MSDN statement!

[Arun Kumar]

That is an old post. I do not find /full either. Maybe they just forgot to update that post.

[GMB]

Actually there is a full shutdown, when you type shutdown /p, it occur a full shutdown.

I'm using Win 8 Pro (x64) and haven't got the "Turn Off Fast Boot" tick box option in Power Settings.

Can someone please confirm it seems to been removed from Power Settings, and if so, is there any other (non command prompt) way to force a full shutdown every time?
