I have enabled fast boot in my copy of Windows 8 but I would like to be able to specifically instruct Windows not to perform a "fast shutdown" whenever I want (without disabling fast boot altogether).

I need to be able to do this because I dual-boot Ubuntu and therefore can't mount an NTFS partition as read/write if Windows has performed a "fast shutdown". (Well okay, I can force the partition to be mounted read/write, but then I could run into data loss/corruption problems.)

  • Check the arguments for shutdown.exe, and also see [this](http://superuser.com/questions/491150/what-does-a-hybrid-boot-do-and-why-wouldnt-i-always-enable-it), [this](http://superuser.com/questions/494861/how-to-add-a-shutdown-tile-windows-8-modern-ui) and [this](http://superuser.com/questions/468687/hybrid-shutdown-in-windows-8-rtm) among others. – Karan Oct 29 '12 at 07:11

An easier way then using the command prompt might be the following:

A full system shutdown is performed by pressing the Shift key at the same time as selecting the shutdown option.

You can run shutdown -s -t 0 for a normal shutdown and shutdown -s -hybrid -t 0 for a hybrid shutdown.

If you always want to do a normal shutdown, follow these steps:

  1. Press the Win + W.

  2. Type change power buttons and press Enter.

    S2

  3. Click Change settings that are currently unavailable.

    S3

  4. Uncheck Turn on fast startup.

    S4

  5. That's it.

    He said he didn't want to turn off fast startup. – Caleb Jares Oct 29 '12 at 19:24

    -1. Your answer does not provide any new information that the previous answer and does so in a less concise way. All you added was a copy-paste from [your other answer](http://superuser.com/questions/494965/wake-on-lan-doesnt-work-in-windows-8), which the OP wasn't interested in. – Caleb Jares Oct 29 '12 at 19:27
  • Your commands in your answer is incorrect. Check it properly. – Elmo Oct 30 '12 at 06:10

Use shutdown /s for a regular shutdown. Use shutdown /hybrid for a fast-boot shutdown.

More information on the shutdown command.

    Are you sure that /s does a full shutdown even when you have fast startup activated? I don't think that the documentation is perfectly clear. The /s documentation just says "Shutdown the computer", not "Full shutdown" like it says under /r. Also, when I measure shutdown times on my computer with a stopwatch, there is no measurable difference between "/s" and "/s /hybrid". – Klas Mellbourn Nov 04 '12 at 07:44

From the Charms bar:

Settings -> Power -> Shift + Shut Down

This disables the 'fast start-up' for the next Windows 8 Session.

Semantically, this tells windows Not to write a hibernation file to disk. Having a hibernation file saved on a Windows NT partition will cause partition mouing tools to fail (as to not corrupt the partition by accident.)

shutdown /s performs a full shutdown. I am not basing my response on having timed startup (versus shutdown /s /hybrid). Rather, I noted that every time I shut down normally, the PendingFileRenameOperations registry value is not processed. I just used shutdown /s with lots of files to process under PendingFileRenameOperations. After having started Windows 8 again, PendingFileRenameOperations has been emptied. This means a full shutdown was performed.
