Windows 11 upgrade aborts and roll back all changes made, how/where can I find out why?

Solution 1:

The Windows 11 upgrade will only roll back if the machine is deemed to be incompatible with Windows 11 at the time it tried to upgrade.

  1. Make sure no Dual Boot (at least for the time being).

  2. Make sure the disk is GPT and you are using UEFI.

  3. Make sure Secure Boot is enabled.

  4. Make sure the machine is equipped with Hardware TPM version 2.

  5. If Windows 10 Home, make sure you are using a Microsoft Account.

Make sure of the above settings and try again.

You may have some software installed that is not Windows 11 compliant. Go through your various software upgrades to check. Make sure IE is not trying to be used. Upgrade to Chromium Edge will fix that. Make sure Office and Adobe are all up to date.
