Cannot log into window error code:0x8009002d

[Pingpong226]

Ever since I tried to upgrade BIOS on Windows 10 (I did it because it was on one of the update list), I cannot log into Windows.

When I put in my password to log in, it shows an error message (code:0x8009002d). I do not have a guest log in as an option. I have to put in the passwords.

What should I do?

Would doing a system restore help? How can I do it when I cannot log in and the computer won’t accept the password even it is correct?

Thank you for joining HP Forums. 

I'll be glad to help you 🙂 

As I understand you cannot log into window error code:0x8009002d,

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Do you have a local account or is it a Microsoft live account?

Have you attempted to reset the password, if it's a Microsoft account, using another device?

While you respond to that, Click here for steps on resetting the password,

Also, here's more assistance related to the same:

A system reboot will help, but only temporarily. It’s only a matter of time when you will get the 0x8009002d error again. Therefore, as soon as you get access to your PC’s desktop, you should turn off the Sleep Mode and reset the PIN password.

• Right-click on Windows key and select Control Panel.
• Select Power Options from the list and click the Change plan settings.
• Find the Put the computer to sleep option, expand the drop-down menu and select Never.
• Then click Save changes.
• To restart your PIN password, click Win key + I and open Accounts.
• Select Sign-in options and find the PIN section.
• Select Remove.
• You should receive a confirmation window, which double checks if you are sure to remove PIN password. If you are, click Remove.
• Finally, enter your account password to approve your account and press OK.
• After that, find Add button under PIN section and click it.
• Enter your new PIN password twice and press OK. That’s it! Not the error 0x8009002d when trying to log in to your Windows 10 account should be gone.

Let me know how that pans out

feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon,

followed by clicking on 'Accepted as Solution' as it would help the community gain more knowledge,

And Have a great day Ahead!

This worked for me.  Been frustrated by it since the HP bios update some weeks back.  Thanks.
