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 think it's an 8.1 issue.  As soon as I switched back to W8, everything is fine again.

    I'm thinking it's a W8,1  Pro only issue; anybody with plain W8  having this probelem? Anyway since so many variable between my wifes SSD Ultrabook and my old HP Desktop; can't be sure of anything; escept when I goat W8.1 pro back in January for the desktop; start up time wiere close to 70 seconds; now only 50 seconds with W8.1. Wifes regular W8.1 is 10 seconds; was  about the same with W8.

    I don't know about everyone else, but I tried uninstalling my third-party AV and it didn't help.  My issue isn't as bad as everyone else' (20 second boot vs 1min boot), but it's still significant enough that I went back to W8.  I ALWAYS keep my startup clean of any unnecessary processes, so that's not the issue either.

    Until Microsoft issues an update specifically fixing this boot issue, I am not going back to 8.1.  I honestly saw no benefit anyway.  Bringing back the start button was nice, but I have start8 anyway.

    Remove your 3rd party Security Suite . Windows Defender (comes intalled on W8.1) maybe in conflict. Check speed with ONLY Defender installed. see if that helps, and, if you still want to reinstall your 3rd party security; hopefull it will integrate with Defender like it should. If not, call Microsoft Security help desk.
