Windows 10: Long wait before seeing login screen, began after power outage. Solved

  1.    15 Jun 2017 #1

    Long wait before seeing login screen, began after power outage.

    Hi guys. I've got a Windows 10 machine, build 15063.0, x64 booting off UEFI on a custom built PC with an ASUS motherboard and AMD processor and graphics. Until yesterday, whenever I booted up my machine, it would be under 10 seconds from the pressing of the power button to the login screen -- pretty good. However, last night, when I was using my machine, I had a momentary power outage and my machine (obviously) shut off. I turned it back on, and it wouldn't boot, so I booted off my installer USB stick and ran chkdsk on my disk. This resulted in a number of errors being repaired, according to chkdsk.

    Next, I ran memory check --- all good.

    I have also uninstalled and reinstalled drivers for graphics cards, run sfc /scannow, run DISM clean up image and defragged my HDD.

    Nothing, however, has fixed this problem:

    When I turn on my computer, it waits ~30sec to 1 min on a black screen (where I can move a cursor with the mouse) until it will display the login screen. Even when the login screen does appear, it takes a few seconds for the password entry prompt to show up after I click in. None of this occurred before the power outage.

    I can confirm that my hardware works otherwise and once I log in, everything works fine.

    Anybody got any idea what it could be?

    PS --- I have disabled integrated graphics and multi-monitor in bios, turned on and off fast boot and have tried legacy boot mode as well.

    Try setting EnableUlps = 0
    Use regedit and search for EnableUlps ... It's usually located in 2 places in the registry.
    Close regedit and reboot.

    Note: Do NOT change the EnableUlps_NA

    Thanks! That worked, now it's all working as it did before.

    I actually had like 10 values of that name in the Registry -- one was set to 1, the rest 0. Changed it to 0 and now it works. Go figure.
