What's Wrong?

After uninstalling Claude Desktop on Windows, the folder
C:\Users\<user>\AppData\Roaming\Claude\ remains with ~10GB of data
(mostly vm_bundles for Cowork).

This is not cleaned up during uninstall and most users won't know
to look in AppData manually.

What Should Happen?

Expected: Uninstaller should either remove app data automatically
or prompt the user ("Delete all app data including VM bundles?").
