In command prompt is said it successfully set up a temp user. I rebooted and it has the same pin error with my regular Windows name and login. No temp user option.

This is so frustrating.

Will this happen with every BIOS update?

I think I need to reload my whole Windows 11 system. I don't want to have to lose everything with each update.

Hello, this is Emily.

There are two issues to solve here. First, you need to figure out the Microsoft account password, whether by remembering it, or resetting it (we will get to that). Then it is just a matter of resetting your PIN, or force the password option to come up on the computer, so you can log in using password instead of PIN.

============

To address the password reset issue - it is very common sometimes text messages don't come through, but such issue is typically temporary due to communication issue between providers. You can try again later, or click on "show me more verification method", to see if you might have left a different contact method, such as an alternative email address, etc.

If you try a different time/day, and it still doesn't work, on the page asking you to enter your code, you can click "show more verification methods" , then select "I don't have any of those." This will start the process of adding another contact method. The only challenge is that it will require a 30-day wait before this change goes into effect. This 30-day waiting policy is intended to protect users whose contact information has been changed by someone else so that they have enough time to reverse the change. This is a security policy that no one can bypass unfortunately.

===============

Once you have the password reset, you can then try to reset your PIN, or use the following method to bring up the password sign in option instead of using PIN, and set up PIN later in Windows Settings.

On the sign in page you are stuck on, click on the power icon on the lower right, hold down Shift key while you choose the restart option. This should boot the computer into WinRe environment.

Now, choose Troubleshoot > Advanced Options > Command Prompt.

In the command prompt window, type in "regedit" to launch the Registry Editor.

In the Registry Editor, select HKEY_LOCAL_MACHINE.

Now on the menu bar, click on File > Load Hive.

In the pop up file selection window, go to This PC > C: drive > Windows > System32 > Config > Software. (Very imporant, it is C drive, not X drive). This should trigger a pop up box. Please enter "1234" for the Keyname.

Back to the Registry Editor, Go to this path:

HKEY_LOCAL_MACHINE\1234\Microsoft\WindowsNT\CurrentVersion\PasswordLess\Device

Now on the right pane double click on "DevicePasswordBuildVersion", and change the data to 0.

You can now restart the computer. And you will now find the "sign in options" to click on, and choose Sign in with Microsoft account, and please use the same Microsoft account you had been using and its credential to sign in.

For the language sign issue, adding another language will work since that's what worked for me. Or go to Settings > Personalization > Taskbar > Turn system icons ON or OFF > turn ON Input indicator.
