Additional Information

With Claude Desktop app this happens when it closes, I get another program is currenlty using this file error. Nothing fixes it except restart.

Last 2 updates have caused this. I just updated to your exact same version.
It would be nice to have a list of items to display so I don't have to kill processes using a file.

If it is not the intent to allow the user/claude to continue working on what they were previously doing, then a user confirm window popup should be displayed that informs the user that any work in progress will need to be killed and resumed post update.

I get this all time, each update in Windows 11 Desktop is hit or miss

Exactly the same, different computers, same problem.

[alexkalner]

the same on each update.
it is annoying a lot.

It's caused by the Cowork service, I believe. Killing processes and stopping services doesn't help. Super annoying. Please fix.

"Can this be fixed ASAP? Doesn’t anyone at Anthropic actually use this? Or is everyone there on a Mac and nobody uses Windows?"
