About this tag
The upgrade errors tag on WindowsForum.com covers issues encountered when attempting to upgrade Windows builds, such as moving from one Insider Preview build to another. Users report multiple errors during the upgrade process, whether using Windows Update or an ISO file, and may face complications like being unable to perform a factory reset. Troubleshooting often involves checking disk space, as insufficient free space on SSDs can contribute to failures, and following various recommended steps to resolve the errors. The tag also touches on concerns about certificate expirations and the urgency of completing upgrades before deadlines. Discussions focus on practical solutions and shared experiences for overcoming these upgrade obstacles.

    Windows 11 Trying to upgrade from 29617 to 29639 and getting multiple errors I can't fix

    Getting the following errors using both WU and ISO. Can't factory reset either. Have two SSDs and both have 1.64 TB of 1.86 TB and 1.51 of 1.86 TB free. I've followed all kinds of steps and can't get this fixed. Not sure what else to do and worried about the certificate expiring on 8/11.
