My Windows 11 laptop suddenly froze, and when I restarted it, BitLocker automatically activated, which I never set up. Now, I'm being prompted for the recovery key but I don't have it. I attempted to log in to my Microsoft account at aka.ms/myrecoverykey to retrieve the key, but I'm stuck because I can't access the two-factor authentication (2FA) due to my old phone number that I no longer have. I also can't access the 2FA settings since my account is linked to that same old number. Unfortunately, the email for resetting this will only arrive after 30 days. Is there any way to resolve this issue, or will I be able to log in to my Microsoft account in 30 days to find my recovery key?

It sounds like something tripped the TPM (Trusted Platform Module), which might happen after hardware changes. If you can't get past the BitLocker lock screen, definitely reach out to Microsoft support. Just a heads up, a lot of their support now is AI-driven, so be prepared to specify your situation clearly. Hang in there!
BitLocker is usually enabled by default on Windows 11 unless you manually disable it. To troubleshoot, try doing a full shutdown by holding the Shift key while clicking 'Shut Down,' then restart your laptop. Once it's back on, quickly check the BitLocker settings to back up your recovery key if you can. If your laptop is managed by a workplace, you may want to contact your IT support team. For personal devices, check other devices where you might be logged into your Microsoft account to see if you can access the recovery key from there. If all else fails, waiting for the reset email or reinstalling Windows with backups could be your last resort.
Always remember, making any changes in the BIOS or your disks could lead to data loss, so ensure you regularly back up all important data before trying anything drastic! If you've tried everything else, just give it some time, and if necessary, plan on reinstalling your system once you can access your email.
