Update Issues

The two Windows pages are reporting different states: Windows Update says build 26220.8079 is current, while the Insider page advertises another build. First run winver, then confirm the selected channel and linked Insider account under Settings > Windows Update > Windows Insider Program. Compare that build with the latest build published for that exact channel; a build offered to another channel will not appear for yours. Next, restart Windows, run the Windows Update troubleshooter through Get Help, and check again. Confirm Windows is activated. Avoid switching channels solely to chase the banner, because some channel changes require an in-place upgrade or clean installation. If 26220.8079 is current for your channel and the warning remains, report it through Feedback Hub under Install and Update, including reproduction data and screenshots; the banner is then likely stale rather than evidence of a missing update.
