For me it was the Microsoft intellimouse, the led one. It had 5 buttons, one on each side so it was also ambidextrous. Now I have a mouse graveyard box.

You’re not safe there either, they had almost the same issue on the Linux version of the product a few months ago.

One issue is that some people are still on windows 7 installs that were upgraded. Windows 7 had a large enough partition for then, but the upgrade now needs more. Unfortunately 2009 Microsoft didn’t anticipate that this should be bigger for 2023 installs. Making it larger is a hassle I wouldn’t want to code either.

Bad news, I have an AMD card and still got the copilot button. It’s probably a very specific version of the software that is an issue.
