Microsoft has brought its new feature called checkpoint cumulative updates starting with KB5043080. However, the error operation is not supported after KB5043080 appears, blocking from installing updates for Windows 11 24H2. In this tutorial, MiniTool introduces much information including the workaround to address this issue.

About Checkpoint Cumulative Updates

Before introducing how to fix operation is not supported after KB5043080, let’s know what Windows 11 checkpoint cumulative updates are first.

In July, Microsoft announced that it would offer a new delivery of continuous innovation – checkpoint cumulative updates on Windows 11 24H2 and Windows Server 2025 with the purpose of reducing the size of monthly updates.

To be specific, the new type of update delivers features and improvements through smaller, incremental differentials. That way, your device only gets the changes since the previous checkpoint cumulative update instead of installing the whole update each time.

This new update way saves bandwidth, time, and disk space. Beginning with the September 2024 update KB5043080, checkpoint updates are available for Copilot PCs. However, there is much buzz about the update issues including the common error operation is not supported after KB5043080.

Windows 11 Operation Is Not Supported

Although the checkpoint cumulative updates feature streamlines the update process, some potential issues will happen, just like the proverb states “With great power comes great responsibility”.

When trying to install KB5043080, the update process gets stuck, followed by a rollback but this leads nowhere. This case was reported by a user in Microsoft’s Windows Insider Feedback Hub. While some users reported the error operation is not supported after KB5043080.

In a support document, Microsoft has not acknowledged the failure of installing Windows KB5043080 but confirmed that error. If you have installed the latest checkpoint cumulative update KB5043080 on a PC, then you try to double-click the .msu package to install a post checkpoint cumulative update, a failure appears with the error message “Operation is not supported, learn more about how to achieve this”.

The reason behind this may have a connection with the FoD (Feature on Demand) or LP (Language Pack) that cannot be updated to the latest update. This problem happens in case you have installed FoD or LP from a local source without connection to Windows Update (WU) or Windows Server Update Services (WSUS).

2. Hit on the Download button depending on your device architecture.

Step 2: Install the .msu Packages

You can choose to manually install these downloaded packages in order from oldest to newest: Just go to C:\Packages and double-click the earliest .msu file to install. Then, install the next .msu file in sequence until you install the latest .msu file.
