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?

I too am experiencing slow boot/shutdown processes on my work machine since the upgrade. Intel Xeon 3.07 GHz, 10gb of RAM. Startup and shutdowns are both in excess of 3 minutes. Mot sure the cause, but there is also constant disk activity during both.
Same problem here. Bootup is very slow. On Windows 8 it took 5 seconds to start the system, now I must wait over 2 minutes. Have a Toshiba notebook, i7, 16gb ram, win 8.1 pro, 128gb ssd + 1000g hdd, bitlocker encrypted.
Noticed the exact same issue here on 2 systems upgraded from Windows 8.0 Pro to 8.1. One has the ASUS P8Z68-V_LX with 8GB ram, etc. and another GIGABTE GA-X79-UD3 configured similar to original post. Used to take only 10 seconds to get to a login screen. Now takes about a minute. Not bad.... but definitely not as quick as it was before.
I have a "new" HP Envy and the startup is fine but the shutdown takes about 4 minutes. Have run also run ccleaner and superantispyware and the shutdown was fine for one time but then went back to the 4 minute shutdown. Also tried reinstalling a couple of the programs to see if that helped. Nothing.
This morning I did a reboot and it took 2 minutes to shutdown and 3 minutes to restart (( back with the long boot problem. I tried to see in the task manager what could be slowing down. I ran ccleaner, superantispyware, then did a shutdown, it took 5 seconds and when i started the PC it took about 30 seconds, it never booted that fast. The slow boot problem seems to be random in my case. Continue to do more investigation.
