Fix Windows 10 Update Error 0xC1900101

[philipnelson]

Tried unsuccessfully to upgrade to windows 10 from windows 8 three times. Yes its still available for free! It got as far as working on updates, but would bow out at 30% each time with the message failed at first boot.. Was about to give up, but then I came across your video, and it worked first time. Just needed to do the first part of your video. I now have windows 10 in all its glory. So thank you so much, and keep up the good work. Philip.

Did everything you said. The result was We've set your pc back to the way it was just before you started the Windows 10 installation

if anyone still has this problem, I too was struggling with those kind of error codes, trying to update my windows for months, until today i was still running on 19h2, trying it over and over again every once in a while and nothing helped

the fix that solved it for me, i didnt found anything about that online, a friend helped me out because he had similar issues, he told me i could just try updating my bios and apparently that was the problem or solved the problem, anyway it worked

might not be your fix but it is another possibility

I fixed this error by updating my BIOS and then installing Windows 10 with the ISO file. Took me hours and was solved thanks to a YouTube comment. THANKS ALEX!

I don't have a "Provisioning" folder in my Registry. I'm running Windows 7, is that why?

It dosen’t even let me run as administrator 😢

[rohitbankar]

When I type first command in command prompt it says access denied and operation failed

[rps]

1. Open Command Prompt as Administrator.
2. In command prompt give the following command and press Enter:

DISM.exe /Online /Cleanup-image /Restorehealth

3. When the DISM operation is completed, type the following command and hit

Enter:

sfc /scannow



This worked for me! If you have messed up with command prompt as administrator this error will occur so, follow above one to repair your system! Ggs
