Many of us are still waiting for the release of Windows 11’s annual major update, version 24H2, which is now available for new PC Copilot+ devices, and with it, Microsoft has introduced smaller “cumulative checkpoint updates” or ‘differential updates’ intended to make monthly updates smaller and faster by downloading only the missing files to your computer – and it looks like it could already be causing problems.
Basically, your PC will only download the new or modified parts of newly released updates instead of downloading the entire update every time.
These updates will begin with the September 2024 checkpoint update, KB5043080, which is now available for Copilot+ PCs. Copilot+ PCs are the next generation of Windows 11 computers from Microsoft, which are designed to take advantage of advanced AI capabilities (most of which are still in development).
An obstacle in the way of Windows Update
Unfortunately, it seems that Microsoft's efforts are being a bit shaky, as after installing update KB5043080, some users are reporting issues.
According to Windows Latest, users have taken to Microsoft’s Windows Insider Feedback Hub to voice their frustrations. One user detailed how their update installation would get stuck at a certain percentage and then begin a rollback procedure. Some users have encountered an “Operation not supported” error, and while Microsoft has not responded to users’ claims about KB5043080 failing to install, it has published a support document on potential issues users could encounter if they have installed the recent September 2024 Patch Tuesday update.
The issue appears to primarily affect people using PCs with certain Intel or AMD chips and users who choose to install the update manually (via the Windows Insider Program or with installation files from the Microsoft Update Catalog).
I imagine Microsoft will acknowledge this issue and release a fix soon, but in the meantime, you'll have to manually resolve this issue if you're affected by downloading and reinstalling update KB5043080 or a newer one.
You can do this by searching for update KB5043080 in the Microsoft Update Catalog. I would recommend checking out Windows Latest's advice on how to make sure you download and install the correct version for your PC (depending on the type of hardware you have). You'll need to follow those instructions step-by-step carefully or use a special Windows command-line tool.
I hope Microsoft releases a fix that’s automatically available soon and that the rest of the 24H2 rollout goes more smoothly. Many of us are still waiting for the update to hit our non-Copilot+ PC devices, and Microsoft doesn’t have the best reputation when it comes to smooth rollouts of major Windows 11 updates. We hope Microsoft continues to fix issues as they arise to make the transition to Windows 11 24H2 as painless as possible.
