Several Windows 11 21H2 computers will not upgrade to 23H2, error code 0xC1900101

Hello Andrew Leonard1

Welcome to the Microsoft Community.

The error code 0xC1900101 you're encountering during the Windows 11 21H2 upgrade process to versions 22H2 or 23H2 is generally associated with driver, firmware, or software incompatibilities. This error, especially in the context of the "SAFE_OS" phase, suggests that the system is running into issues when attempting to load or execute critical drivers or services during the upgrade process.

Several Windows 11 21H2 computers will not upgrade to 23H2, error code 0xC1900101

We have about 20 computers under management that will not upgrade their build to 22H2 or 23H2. They consistently produce the error code 0xC1900101. This is a failing of the "SAFE_OS" mode where it boots into a Windows PE instance for the purpose of finishing the update, but it apparently is crashing in that step. I've tried various methods of performing the update. We've used the ISO inside of Windows, Windows Upgrade Assistant, and booting the computer off the ISO and none of them have helped us move forward. I'd prefer not to wipe and reload these computers. Has anyone else run into this?

Thanks,

Andrew

Windows 11 Installation Error Error Code: 0xC1900101 0x4001

Hi MJBurns,

The setup platform crashed with error code 0xc0000005. This is a known issue with the recent Windows 11 setup modules.

Many users face this issue, and buggy acmigration.dll is to blame. Replacing acmigration.dll with a much older version seems to have helped some users.

SOLUTION/WORKAROUND

Step 1: You can use this batch script (GitHub) to download the Windows 21H2 version of the ISO.

Step 2: Download the Windows 11 23H2 ISO from https://www.microsoft.com/software-download/windows11

After downloading the two ISOs, do one of the following:

Option 1: Run setup.exe from the 21H2 ISO and point to the 23H2 WIM

Mount the 21H2 ISO and the 23H2 ISOs -- let's say E:\ and F:\, respectively.

Run Setup.exe from the 21H2 ISO, but mention the "/InstallFrom" argument and point it to the 23H2 install.wim.

From admin Command Prompt:

• E:\setup.exe /installfrom "F:\sources\install.wim"
  

(or)

Option 2: First, upgrade to 21H2. And then upgrade to 23H2.

Run E:\Setup.exe and install the 21H2 version.

Once done, upgrade to 23H2 using the 23H2 ISO.
