Hi Pidgeonpost! It seems like you're in quite the predicament with the account migration from Windows 10 to Windows 11 Pro. This situation can be frustrating, especially with the PIN and phone verification issues.
From what you've described, you’re experiencing a classic case of catch-22 with the two-factor authentication system. Here are a few suggestions that might help you navigate this situation:
1. Access the Microsoft Account Recovery Page: If you haven't already, try accessing the Microsoft account recovery page. This might allow you to recover or change the registered phone number without needing to verify the old one.
2. Alternative Verification Methods: Check if Microsoft offers an alternative verification method for the account, such as email verification, which might allow you to update her details without relying on the landline.
3. Use Safe Mode: If you can boot into Safe Mode, you may be able to get into her account without going through the PIN verification process. From there, you could potentially make changes to the account settings or set a password instead.
4. Use a Different Device: If you have access to a different device (like a smartphone or tablet), try logging in to the Microsoft account through that. Sometimes, you can manage account settings more easily from the Microsoft website, which might bypass some of the restrictions you're experiencing on the new system.
5. Consider Waiting for the 30 Days: While it might be cumbersome, waiting for the 30 days for the registered phone number to be updated might be the safest route if all else fails. Once that time passes, you should be able to receive the verification code on her mobile number.
6. Restore Partition: Reinstalling Windows 11 might work, but you will likely face the same issues after the reinstallation. If possible, try to resolve the account access issues first as simply reformatting may not save any data.
7. Talk to Microsoft Again: Sometimes, speaking to another support agent can yield different outcomes. They might have additional options or could potentially escalate the matter.
To sum it up, avoid reinstalling unless necessary, and exhaust other avenues for verification first. Hopefully, one of these methods will help you break out of this loop! If you need further assistance or have updates, feel free to ask!
