Hello Medipally Rishitha, Thank you for posting in Q&A forum. May I ask what name you have changed? Is it the user name of the Windows system? You can send screenshots of the problems you encounter on the forum. If the issue you are facing is related to the username of the Win11 system, it may be because you are using a digital ID associated with a Microsoft account, rather than a username. Usually, this situation occurs when logging in with a Microsoft account. I hope the information above is helpful. If you have any questions or concerns, please feel free to let us know. Best Regards, Daisy Zhou
