Windows 8.1 Upgrade Failure

I just put W8 on my main system and then tried the 8.1 upgrade and got an error saying it ran into problems and gave me this code: 0xC1900101 0x40017. That happened to me on my laptop as well and all it required was for me to install one security update and then it was fine. Well, my computer this time shows all updates are current. I didn't have time to research the error and so I thought I'd post it here and see if I can save myself some time. If you need the specs of my system, I'll have to post them later as I won't be home until late this afternoon.

Thanks and have a great day!

Mike
