Windows 11 25H2 Update Not Showing in Windows Update on Parallels 26 (M4 Max Macbook Pro)

I have seen a similar question asked several months ago. Windows 11 25H2 has now been out quite some time. I don't see any settings which would prevent me from receiving any updates. I reboot the VM every time I use it. I am up to date on all Windows updates that I see are available. Parallels software has been updated to the latest version and Tools is up to date.

Is there something delaying the rollout to Parallels VMs?

    I finally found the URL for Windows 11 for ARM 25H2 ISO download. I don't see any mention that Windows 11 for ARM update should appear in Windows Update. Why nobody seems to be able to answer this question amazes me.

    I downloaded the ISO, mounted it, and ran setup. It completed the installation in the VM without issue. When I look at the System About information it states I am now running 25H2. I ran Windows Update again and there were a few more updates.

    If the Windows 11 25H2 update is not showing up in your Parallels VM, there could be a few reasons for this. It's possible that the rollout of the update is staggered and may not yet be available for all users or specific configurations, including virtual machines. Additionally, ensure that your Windows Update settings are properly configured to receive updates and that there are no pending updates that might be blocking the installation of new ones.

    You can try the following steps to troubleshoot:

    1. Check for Updates Manually: Go to Settings > Windows Update and click on "Check for updates" to see if the update appears.
    2. Use Windows Installation Assistant: If the update still does not show, consider using the Windows 11 Installation Assistant or downloading the latest ISO from the Microsoft Software Download page.
    3. Contact Support: If issues persist, contacting Microsoft Support may provide additional assistance specific to your setup.

    It's also worth noting that updates can sometimes be delayed for virtual environments due to compatibility or testing requirements by Microsoft.
