A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I found that process too. It was called Clipboard User Service_96a2841. The 96a2841 is an instance ID. It changes every time you boot up. I found out how to disable it in the registry because it can't be disabled in services.msc. The latter gives an invalid parameter error if you try and disable it there. After a couple times of doing it and just closing the dialogue with the X in the corner, it does disable, but only for that boot-up.
After all that, Clipboard User Service isn't the problem. The error just continues and continues with that disabled. The error is 100% caused by Microsoft incompetent programming, not this Clipboard service or Logitech - which I don't even have. It always says the clipboard is locked by another user. That means that in something with Microsoft 365 working with OneDrive, Microsoft has set up another user to do all its useless shenanigans and, for no reason whatsoever, lock the clipboard while it's doing them.
