It's like you're not reading to the description of the problem. Link to Windows comes preinstalled on many devices. You can't uninstall it on those devices. You can sign out and clear the data. As soon as you sign back in, the old computers reappear. As shown in the original poster's screen shot of his https://account.microsoft.com/devices the problem computer does not appear there, so obviously there's no way to do anything on the PC itself -- it no longer exists. Same thing for me.
There must be data stored on an MS server specific to the Link to Windows app for Android. How do we alter THAT data and remove a no-longer-in use PC (or duplicates)?
This is a problem affecting many users. Almost 100 people have reported the same problem at this thread: https://answers.microsoft.com/en-us/windows/forum/all/remove-inaccessible-computers-from-link-to-windows/b818db1f-96bd-4168-b834-95063e83a6dd?page=3
There is no resolution there either. But the one thing that's worse than not getting an answer is something like this response that shows the responder didn't even bother to read the symptoms before posting a response that obviously on its face can't work based on the problem description (the parts about uninstalling Phone Link on the computer).
People who don't know better may spend their time trying to do these things, possibly causing additional problems. Microsoft should ban people who post responses like this who show they have not even read the description of the problem and give answers that obviously can't work. Bad, wrong information is worse than no information (plus, with all the AI stuff, it fuels wrong responses from the AI too.)
