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?

    Problem isolated...

    On my setup, it was the Qualcomm Atheros QCA9565 Bluetooth 4.0 + HS Adapter driver.  I disabled Bluetooth, and the problem went away.

    I will report the issue to HP, and ask for a fix.

    Thanks!

    Problem solved.  Uninstalling and re-installing the Bluetooth driver fixed the problem for me.

    Several applications broke when the 8.1 "upgrade" occurred.  My AV and VPN applications had to be removed and re-installed, and now we can add the Bluetooth driver to the list.

    I'm happy to be over this issue, but am very disappointed in the amount of trouble MS has caused with this very sloppy set of updates.  I have many Win8 clients that will eventually be forced into 8.1, and am not relishing the nightmare to come.

    The Bluetooth driver was the problem for me also.  Just go to the Device Manager (Windows key X).  Find your Bluetooth driver.  In my case it was "Dell Wireless 1703 Bluetooth."  Right click on the driver and choose, "Update Driver Software," then select "Search automatically for updated driver."  Your driver will be updated if it is out of date.  Worked for me!

    I've been following this thread since the beginning and I had the same issue months ago.  I finally decided to give 8.1 another shot since my laptop's wifi has been acting up.  Everything seems to be fine now.  Boots up in ~17 seconds and shutdown like normal.  Pretty happy with Win 8.1... they fixed pretty much all of the issues I had with it.
