Hi Ruchika,
Thank you for the information provided in your private message.
I'm pleased to inform you that your legal name has been successfully updated as requested. The changes should be reflected on your Learn profile within the next 24 hours.
Kindly review the private message I have sent and confirm that the changes are visible. Please note that it may take up to 24 hours before you can attempt to register for any exams. Should the changes still not be reflected on your profile after 24 hours, please respond to the private message with a screenshot.
To ensure that your name has been updated also in your Pearson VUE profile, kindly follow the work around provided below to view the changes:
Visit the Browse Credentials | Microsoft Learn and select any exam.
Click the schedule button. You may be prompted to sign in or create your Learn Profile. We recommend using your personal Microsoft account (MSA).
