I am trying to install the new Windows 11 update from Windows Update, but I keep getting error 0xc1900101.
The installation starts, and after a couple restarts, it says:
" Attempting to recover installation "
" Undoing changes made to your computer "
And then I am greeted with error 0xc1900101 on Windows Update.

2021-08-08T01:32:00+00:00 Had the same issue with my Dell XPS 9700 running on latest windows 10, no matter I switch it to dev or beta channel, I got the same issue, it downloads the update successfully and then installed, asked me to reboot, then I saw the progress bar reach to 100%, then reboot, then I got this error, then recover back to windows 10.
I tried to disable some of the drivers, like intel and nvidia's video driver, but didn't take effect.

2021-08-07T21:59:32+00:00 My personal laptop does not have a network connection on it. At home I only use wifi. At work, where there are 6,000 computers, there are RJ45 connectors and network adapters.
I have been on the DEV track for many years. I dropped to the beta track when others recommended it along with Microsoft. I get to the network through Microsoft Wi-Fi Direct Virtual Adapters.
My technical skills are up there with the top 10%, but thank you for the suggestion I should get out.
Back to the original issue. One respondent said to check my network card. I did. I have. THAT is not the issue for me.

The issue with mine was that windows was installing a driver for a realtek network interface that was like 10 years old causing the upgrade to fail I just disabled it in the BIOS so it didn't think it had a driver to install and everything went smoothly.
