Hello Samira,
Thank you for contacting Microsoft’s Community.
As we understand, you wish to change your name.
Please keep in mind that your Certification profile must match your ID, so we highly recommend you use the name that appears on your international passport in case you are required to verify that information with an official ID.
Also when filling out any personal information for the Certification Profile, the system only allows the use of Latin basic alphabet, please avoid special characters such as: ă, â, á, é, í, î, ó, ẹ, ị, ł, ọ, ụ, ã, ả, ẻ, ỉ, ỏ, ủ, ñ, č, ď, ě, í, ň, ř, š, ș, ş, ť, ț, ú, ů, ž, đ, \, /, ., *, ?, :.
If you wish to proceed with the legal name change, please fill in this form: Microsoft Certification Profile Name Change Request Form and share with us your Ticket ID through Private Message.
To use the Private Message Feature please look at the right side of the page and click the icon seen in the image below:

We are looking forward to your response. Please keep in mind, if no response is received, we will close the case in the next two business days.
Best wishes,
