    Critical Error message on boot up - new 10103 install on laptop

    I just upgraded my Dell Latitude E6400 from Win7 to Win10 1030 (not clean install). Everything looked good a first and I did the first set of Windows Updates. Shutoff laptop and set aside.

    I just cam back to it and upon restarting I get an error message.

    There is a window/box in the middle of the desktop that says:
    A critical error has occurred in the Shell Infrastructure Host. Start Menu, Cortana, and some Apps may not be available. Please save your work and sign-out to recover.
    The box with "Sign-Out Now"

    I have tried three times to reboot (cold restart too) but it keeps coming back with this error. Has anyone seen this before?

    I can open Task Manager and third-party media player on my desktop (but the Error message stays on top). I can not access anything from the taskbar and most taskbar icons are not loaded.

    I'm going to try to boot into safe mode.

    Still trying to figure this out. Did a system "Reset" which basically reinstalled Win10, but I'm still getting the critical error.
    I'll go back into Recovery Mode and see what other options are available.

    One frustrating part is that I switched over to a Microsoft account and now I have to type in my full 12 digit password everytime this thing boots up. I should have left it as a local account until I was sure everything was working.

Error Message on restarting PC
I formatted and installed 10041 yesterday and I'm getting this error when I tell the PC to restart. Windows seems to be functioning properly and its probably just a quirk of the development which should just disappear in final build.
