My PC is Windows 11 compatible. The Windows 11 Installation Assistant is a Microsoft approved method and I made no attempt to trick the installation program. I did however find shortcomings in the Microsoft program.

My first installation attempt was made with an incompatible graphics card (insufficient Direct X???). The Microsoft program ought to have picked this up in its checks before proceeding with the upgrade but I only found out there was a problem when the program crashed with some cryptic error number. A third party program (a checker built into aomei partition assistant) revealed the incompatibility the MS program should have detected.

I still had what I think were graphic card issues with the upgrades without the incompatible card installed but I was able to find my way through that. Again, I attribute this to failures in the MS program.

Sine then, I have used the same Assistant method on my new Dell laptop. That went through without issue.
