I do have the same issue, the update keeps at 0% and not moving at all. There's no problem with my Windows Update and there might be some other thing which caused the problem since 25H2 is just a recent release. When I searched and found there are 2 different matters;

• 2025-09 Cumulative Update for Windows 11, version 24H2 for x64-based Systems (KB5065426)(26200.6584)
• 2025-09 Cumulative Update for Windows 11, version 25H2 for x64-based Systems (KB5065426)(26200.6584)

I'm glad if here's any .MSU which I can do manual updates (the above listed KB is not listed in Windows Catalogue).

Thanks alot !

If the issue persists, open Settings > System > Recovery.

Few things to check on the PC

• Unplug all external peripherals except for the Mouse, Keyboard, and LAN cable before starting
• Disable or uninstall any third-party Antivirus program to prevent it from interfering with the upgrade

Under Fix problems using Windows Update, click Reinstall Now

Once completed, your system will restart.
