Feature Request: Allow Custom User Profile Folder Name during Microsoft Account OOBE Setup

Currently, when setting up Windows 11 using a mandatory Microsoft Account (MSA), the operating system automatically generates a truncated 5-character folder name in "C:\Users" based on the first five letters of the user's email address.

For professionals using high-end workstations, this behaviour is problematic for several reasons:

1. Professionalism: Truncated names like "siddh" instead of "Siddharth Shankar" look unprofessional in file paths and environment variables.
2. Scripting and Development: Many automated scripts and terminal-based workflows rely on consistent, predictable naming conventions that align with the user's actual identity.
3. Accessibility: Users should have agency over their local directory structure without needing to resort to OOBE\BYPASSNRO hacks or post-install Registry edits, which can be risky and time-consuming.

Request: Please provide an "Advanced" or "Edit" option during the "Who is going to use this PC?" screen that allows users to manually define their local folder name while still signing in with their Microsoft Account.

This change would align Windows 11 with modern UX standards of personalization and user control.
