"Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017"

Hi,

I purchased widows 8 a while back and everything has been horrible. I know my pc was a little old but before I purchased the software i downloaded the upgrade assistant and followed the instructions given. I contacted support so many times with issues, i even purchased a subscription from iyogi, anti virus software, everything. But my computer still crashed, so finally i sent it to a local computer technician. Which he informed me that my desktop cannot run windows 8. Now, i know microsoft technicians helped me reinstall this software several times and say good-bye. It worked a little while but when i tried to send emails same problem. So, my warranty on the software is expired. So I contact them again to ask for help with reinstalling, the technician finally told me i couldnt use it because of my monitor. Out of all the previous times i had them help me, no one said anything about that. So now i have purchased windows 8 and i cant use it now my windows 7 is screwed up. What must I do.

I'm not using any virus protection. This is on a clean SSD that I just bought that I wanted to load Windows 10 onto. 

I am starting to suspect that the ASUS Motherboard isn't compatible.

Don't know how many of the threads you've seen, so I'll just repeat my experience. Maybe it will help others. I don't remember the person who posted it so I can't take credit, but I was getting these same messages. For me, it turned out that my Avast virus protection program was preventing the install. I temporarily uninstalled Avast (and activated Windows Defender just in case). With Avast uninstalled I was able to go through the upgrade to 8.1 successfully, then reinstalled my Avast. One previous reply to this said they had Norton - which I also had in the beginning - and 8.1 installed without any problem with Norton, so I'm not sure what the other issue might be there. Good luck.

I have Norton Security Suite, and have not seen it listed at a problem. As I noted earlier, the major annoyance of this issue is the MS msg saying the upgrade failed, but does not list reason[s].

Ergo: After many tries, I give up. Will simply stay with 8.0. Not worth all this frustration.

You don't say what virus protection program you're using. I am not a technician so all I can attest to is the temporary removal of Avast to install 8.1. That worked for me, but I can't offer any other remedy. Good luck.
