Hello, Jaysing!
Thank you for contacting Microsoft's Community.
As we understand from your post, you need to change the legal name in your account to match your ID for your upcoming exam. We are happy to help you!
Currently you can complete the Legal Name change by following the steps provided to manage your certification profile:
Sign in to your certification profile.
Select the "Edit profile" button, then select the "Request change" link next to your legal name.
Provide the name from your identification (Latin characters only) to change to and submit the request for approval. You will receive an email with your support request number, and a second email within 24 business hours (Monday-Friday) confirming if your request has been approved or if a support agent needs additional validation.
Please note changes may take up to 72 hours to reflect across systems.
For further information and steps to update your information you can check the following link:
Since the Legal name can take up to 72 hours to complete the change of your name, we strongly recommend you to reschedule your exam to avoid inconviniences.
