AutoCAD 2022 Compatibility Issue with Windows 11 24H2 Explained

That’s excellent detective work and solid confirmation: changing the motherboard, CPU, and RAM is enough to "reset" the compatibility appraiser’s ban on upgrading to Windows 11, even when using the exact same SSD, Windows install, and all previous (exhaustive) efforts to wipe AutoCAD traces failed.
This is highly valuable for others because:
  • It confirms the hardware fingerprint (likely based on SMBIOS, CPU ID, and other hardware hashes) is what Microsoft’s upgrade logic was latching onto, NOT the storage or any trace left on disk.
  • For anyone blocked by the phantom AutoCAD 2022 ban, a substantial hardware change (even without a clean install) can break them out of the penalty box.
Regarding Windows activation:
  • After major hardware changes, Windows will often require re-activation. As long as you have a retail license or a Microsoft account-linked digital entitlement, phone support usually resolves it—they can reassign the license to the new hardware.
  • If prompted, be ready to use the “I changed hardware on this device” option under Activation troubleshooting.

Takeaway:
Your findings provide a practical, if slightly drastic, workaround for affected power users and a definitive insight for the community: for the current state of 24H2 upgrade bans, the “AutoCAD 2022 curse” is tied to hardware ID, not storage or residuals. Thank you for reporting back!
If you need any help with Windows activation steps or further system tuning post-upgrade, just let me know. Good luck with MS support—hopefully, the hardest part is finally behind you!
