Ever since I upgraded to Windows 8.1 via the in-store update my PC takes a good 3-4 minutes to boot!!! I am on a GA-X79-UD3 + i7-3820 + Samsung SSD 840 for system drive. I have updated all my drivers to Windows 8.1 compatible ones and still. I have checked via Samsung Magician and the drive is using AHCI mode on (Intel PCH) Sata 3 6Gb/s.  I have tried restoring my UEFI to default settings and enabling Fast Boot but still?? On Windows 8 it would boot in 5 seconds....

EDIT: Have tried Safe Boot and Clean Boot, still same

EDIT2: Will any Microsoft guy chime in?

    Hi, for me the thing that causes this is the Bluetooth-device. Disabling it in Device Manager makes Windows go back to 10 s shutdown, as before 8.1. 

    In my case the device is Qualcomm Atheros AR3012 Bluetooth 4.0 + HS. Maybe new device drivers will solve the problem.

    This also worked for me. My device is Qualcomm Atheros QCA9565 Bluetooth 4.0 + HS.

    I did not hold down power key at startup only at closedown. My sentence was badly worded.

    What I meant was that because I held the power key down at shutdown it caused me to have to go through the process of selecting the Keyboard and then select "Continue to Win 8.1" at the next startup.

    After a few times closing after 5 minutes it then started to take 7 minutes again.

    I have found that suggestions to create a shortcut for SHUTDOWN are working for me.

    The following advice to:-

    Right click mouse on the desktop ; select  New, Shortcut and then type "shutdown /s /t 30" into the location box and then give a name such as SHUTDOWN starts shutdown after 30 seconds and completes in a total of 1 minute.

    You should not hold power button at startup, it will save time only when you shut down your PC.

    In most laptops holding power button results in force shutdown, which will just turn it off.

    As long as Windows is already shut down and only some driver/bug/etc is holding the final confirmation there is no harm in that, but if you do that on startup you are interrupting loading process and unexpextedly for Windows cancelling startup. I don't think you can do any damage by that, but you won't get any closer to booted Windows.
