How Can I Fix Error 0x8007042B – 0x2000D When Upgrading Windows?

It sounds like the issue might be due to corrupted user profiles. A common fix is to delete all but the primary user profile. Just make sure to keep your main account intact. Also, since you're running 24H, remember that the update should work even on older Intel processors. Give that a shot and see if it helps!

In my experience, skipping updates initially can actually help speed up the upgrade process. It’s worth trying to check for updates at the start before proceeding. If that doesn't resolve your issue, you might want to use a tool from Microsoft called setupdiag.exe to gather detailed logs. Run it with the command setupdiag.exe /verbose and look through the APPRAISER_SetupOutput.xml file for any lines that say blockmigration=true. If there are additional blocks showing, use the command pnputil /delete-driver oemXX.inf /uninstall /force to remove them, then try upgrading again.
