[Important Notice]
We have identified an issue affecting the login screen in versions 1.16 to 1.28.
Specifically, using “Delete user” inside the “Advanced operation” menu may in certain cases delete an unintended user account.
(Deleting a user from “Change user information” in the title bar is not affected)
If you are using any of the affected versions, please update to version 1.29 or later as soon as possible.
We sincerely apologize for the inconvenience this may have caused.
If the deleted user folder still exists in the Recycle Bin, there is a possibility of recovering it using the new “Restoring a deleted user” feature available in version 1.29 or later.
As of November 22, 2025.
