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 : Boot is now X4 with Win 8.1 compared to Win8 !! (Dell XPS i7, Win Pro 64bits)

    I have tried different tests (with and without TuneUp, Bitdefender, etc... looking for a new user profile, changing advanced parameters in boot via msconfig...) no major result to decrease boot time.

    A lot of people are claiming (english, french...) on this incredible problem which is "indigne" (i am french) of Microsoft without any answer from their side.

    I am very angry again MS !!

    The thing that boggles my mind is, if it IS processes/services hanging on shutdown, what is causing this problem? Surely it's not an I/O issue with all these SSD users. So maybe it's registry related? Windows architecture isn't my forte (CCNA student) so If anyone's the wiser here maybe it would be worth poking around and seeing what's changed between 8.0, 8.1 and even 8.1 to 8.1 Pro?

    PDTScully,

    That did a great job at increasing the boot time!  I think it might be booting faster; 5 to 6 seconds!! Thank you!!

    The shutdown process is still really slow.  The fix for that will take some time.  Since Microsoft has been just giving out the same advice.  I can assume they do not know what is wrong and that it is probably something to do with a process hanging; a driver I bet.  My next move will be to see if there is any software that can log the shutdown process and the time it takes to store or remove resources.

    I made the 2 changes as you had suggested (# of proc's & max memory), but just making those 2 changes did not have an impact for me. Guessing it probably is a combination of all the other changes along with this one that made the difference.
