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?

    Same problem here. Running an i7 Fujitsu T902 that used to boot in seconds, now takes well over a minute or two. Lots of "Please Wait" and blank screen. Safe mode has no effect, all drivers are up to date.

    Same problem here - upgraded to Windows 8.1 same day I got my laptop with Windows 8 and loading times are very disappointing.

    Each load and shutdown were taking about 3-5 minutes, rotating circles are going fast as they should, but before them (in case of boot) and after (in case of shutdown) there was 3-5 minutes of black screen with laptop fan and power indicator being on.

    I've managed to fix boot time and reduce black screen to 10 seconds by removing Intel HD graphics and Nvidia drivers pre-installed by Acer and installing fresh ones from Intel and Nvidia websites, but this did not affect shutdown time, it is still taking 3-5 minutes of black screen to shut down.

    Now I just hold power button and force shutdown as soon as screen goes black, this does not affect anything and Windows does not see this as a crash.

    Still, would be nice to fix this.

    Thanks for that. I have now updated all drivers and the first time shutdown was quick but now it has just reduced from over SEVEN minutes to five mins 30 seconds. Startup is now faster at about 1 minute. Thanks for the tip about just holding down the button after black screen.

    Microsoft need to fix the base causes.
