Windows login locked out after bios update TPM related?

Hey all, I am on windows 11 and updated my bios today and now I can't sign into my account, the pin isn't recognised and the account / email password is saying it's incorrect when it isn't.

When I updated the bios it asked about clearing tpm and gave the option of yes or no, I don't have bit locker so I pressed yes

I am really not sure how to get back into my account as it doesn't let me reset the pin either on that login page as it asks me to retry once it fails

I did try a regedit to try passwordless but that didn't allow me to get into my desktop unfortunately

CPU: AMD 5900X
Motherboard: ROG Strix X570-E Gaming
OS: Windows 11 Pro

Is this any help: -

I wonder if this link will help at all.

Hey thank you for your reply. Sadly I can't login to enable/ disable the TPM, I do believe the TPM was already wiped on the BIOS update as it did ask to remove it, although now I can't add a new pin back the login screen just has me in a loop retrying and failing

Are you saying that you can't get into the BIOS/UEFI by pressing some 'Function' key when switching on? Typically these include 'Del' key, F2, F9 as examples.

Sorry I can get into the BIOS just fine I will try to enable / disable the TPM setting in hopes it works here, I will report back with some pictures of what I'm seeing with this. I appreciate everyone's help with this so far, thanks!

I remember this topic on this or another forum. I'm don't remember what the solution was. Try doing a search on this forum. If you don't find it try searching on Windows 10 forum. I'm going to take it that you don't have the option to use your password. As you now know your Pin # is stored in the TPM. I'm bouncing back and forth from doing something and being on the computer. If I get a chance I'll try to find it.

I found this doing a quick search. I don't know it will work or not. Redirecting

Hey I have tried disabling TPM in the BIOS and then attempting to sign into windows 11, but sadly I couldn't log in it says the password is incorrect still. I did try enabling TPM also but this also stated the password is incorrect, although that password is correct as I can log into the account using the same password on another system

I just tried safe mode and it says the following:

"Your pin is no longer available due to a change to the security settings on this device. Restart your device to see if that fixes the problem"

Would removing the pin somehow help here so I can reset it if that is possible?

You can make an installer usb, boot it, “repair” and use Command Prompt. Run:

move c:\windows\system32\utilman.exe c:\

copy c:\windows\system32\cmd.exe

c:\windows\system32\utilman.exe



Then boot back into your windows. Click the ease of access icon in bottom right. It will open command prompt as admin. Run:

net user Administrator /active:yes

Then you can log in with the system admin acct and troubleshoot

Hey I actually do have a dual boot on this system so I can boot into windows 10 just fine on the same account, so I assume I can do this through the windows 10 install as I can see the drive with windows 11 on it

Yeah you can do that. Just use the appropriate drive letters when copying or it’ll wind up replacing ease of access with Cmd on your win 10.

Hey thank you for that, although sadly with that it still states "the user name or password is incorrect" It's quite the challenge to get back into this system

Sorry I have managed to get into the system administrator account on windows 11, although I'm not sure what to do from here to get into my main admin user account with my email on the system

@mysticninja
From the Admin account, you could try going to Settings > Accounts > Other Users and add another account, then log in using the new account.

Don't forget to check the rest of the account settings while you are there.

If that is successful, then you could delete the old non-working account.

Don't forget to move c:\utilman.exe back to c:\windows\system32\utilman.exe, if you moved it.

Hey I can get into a new admin account on windows 11 fine, but I really would like to get back into my main Microsoft account if possible. It seems impossible to get back into that account all of the attempts do far throw the incorrect password message

Does it give you password option at login or only pin?

@mysticninja
I doubt you will ever get back into that account since you wiped the TPM info when you updated.

Lots of things are encrypted by the TPM and the keys used for that encryption are now gone.

That's why I suggested creating a new account.

You could try a repair install:

I'm not sure how successful that would be though.

It gives me only a password option, the pin icon if I press that then it also asks for the password rather than the pin I had on this account before. The pin icon says "Want to sign in faster and more securely? enter your password to set up windows hello" both password fields show the password as Incorrect when it is correct

Try removing the pin and see if passwords works

*be sure you browse to the correct user’s appdata*
