Errors 0xC1900101 0x2000C while updating from 8 to 8.1 on Win-Store

Thank you for the updated information.  We appreciate you sharing this with us.  Good Luck.

I got it to work! I am almost certain the problem was overheating although there was nothing on the log about it. I propped my laptop up so it would have better air flow and the update went through. I had done an attempt a few hours before that failed so the only difference between the success and the fail was the airflow.

Did you uninstall Anti-virus software?

Did you empty SoftwareDistribution Folder?

Was there more to the message than error 2000c?  Ex:  analog input canot display this video mode,when the computer restarts I get error message 0xc1900101-0x2000c

I am back to the 2000c error. I had the 20017 error twice but I did again today and now I have this. My computer must have some weird issues.

Thanks for keeping us informed.  Did you see this article?
