How to Fix the “Someone Else Is Still Using This PC” Error in Windows

Did you run into a “someone else is still using this PC” pop-up window while restarting or shutting down your Windows computer? Was there a secondary message that any unsaved data will be lost for other users on the device? Don’t let these pop-ups alarm you. The warning pointing to simultaneous logins doesn’t necessarily mean that someone else has logged in to your PC. Mostly, the error results from invalid user login instances, but sometimes it shows up out of the blue with no traceable cause. It is easy to resolve, though, and does not require any advanced troubleshooting techniques. The following Microsoft-recommended fixes for Windows 11 and Windows 10 can get rid of the error message for you.
