I can't update Windows 11 - Error 0xc1900101

Anonymous

Windows Specifications:

Edition Windows 11 Pro

Version 23H2

Installed on ‎13/‎05/‎2022

OS build 22635.4805

Experience Windows Feature Experience Pack 1000.22700.1071.0

** This problem has been fixed! I suggest following all of** [Ramesh Srinivasan**'s steps in the thread. ]**

Hello! I am currently a Windows Insider in the Beta channel. I received an optional feature update called Windows 11 Insider Preview 10.0.26120.3073 (ge_release_upr).

What happens:

-I download and install the update. My computer restarts, and an "Updates are underway" screen reaches 100%. It then restarts again. It then reaches another update screen, where it takes a while.

-Once it reaches a percentage (usually 68%~~ ish), the PC shuts down, turns itself on, and repeats again and again until it attempts to revert the update. I can then come back to Windows Update, and it shows me this error:

What I've tried to fix it:

-sfc /scannow. Does not find anything unusual.

-dism /online /cleanup-image /restorehealth. Does not complete and gets stuck.

-Secure boot (PC was already in secure boot by default)

-Restarting

-Updating drivers (GPU and CPU)

-chkdsk c: found nothing out of the ordinary.

-SetupDiag.exe does not run, and I can't find any solution.

-Install other optional updates. (the only one that remains is this problematic one)

-Windows Update Troubleshooter finds a "problem" but does not actually fix the error.

Another special thing to note: As said above, I was able to install other small updates just fine along with trying to install this problematic one. Only this update encounters an error, and all others that I've tried so far have been successfully installed. I am also aware that this is a generic error code.

Hopefully someone can help me with this issue. I would like to be able to update again without having to wipe my data. I'll only do so as a last resort.

Thanks community!

Please clean boot the system using msconfig. A clean boot is the process of starting Windows without loading third-party apps and services. Please see this Microsoft article for more information.

(Step 3 is very important. You need to first enable "Hide all Microsoft Services" before clicking "Disable all".)

Once done, please try to upgrade to 24H2.

Here you go! It was unable to be turned on as there were incompatible drivers:

Hi Skorper,

Please open Windows Security and enable Memory Integrity. If it shows a list of incompatible drivers, post the screenshot of that page.

Hi Skorper, This is Ramesh.

0xc1900101 errors are mostly drivers-related. Please share your setup logs to help me determine why the setup failed.
```
• Open the "C:\$WINDOWS.~BT\Sources\" folder.

• Select the two folders, "Panther" and "Rollback" (if present).

• Copy the two folders to the desktop.

• Delete the GenuineTicket.xml file, if exists, in the Panther folder.

• Zip the two folders and upload the zip file to OneDrive and share the link here. 
```
