As you know, Windows Hello offers you quick access to computers since you can log in to your Windows devices three times faster compared to passwords with the help of the camera via Face recognition and fingerprint reader. This way, Windows Hello will recognize you right away. However, there are also times when you might encounter some problems when using Windows Hello. For one, if you are trying to add the PIN method to Windows Hello on your Windows 10 computer but you suddenly encountered an error code of 0x801c004d or if you are trying to use your existing pin and you encounter an error code of 0x80070490 along with an error message that says, “Not recognized”, then read on as this post will guide you on how you can fix both of these errors. Here is the complete content for both errors:
If you got any of these two errors, there are several potential fixes you can check out to resolve them. You can try to check for any Windows Updates or create the PIN again or check the CNG Key Isolation Service. You could also try to reset the TPM or create a new User Account. For more information, follow the instructions provided below.
The first thing you can do is to check for any available Windows Updates. It is possible that your computer may be outdated and is the reason why you’re having troubles with Windows Hello. To check for Windows Updates, just go to Settings and from there, head over to the Update and Security section and click on Windows Updates located on the left pane, and then click on the Check for Updates option. Wait until the process of checking updates is completed and if it finds new updates, install it. After you install the new Windows Updates, check if you can now add the PIN on Windows Hello or not.
The next thing you can do is to create the PIN again by signing out and signing in again and then try creating the PIN once more. If this does not work, you can try restarting your computer and creating the PIN again. You could also try removing the PIN and then change it.
The CNG Key Isolation Service is the one that stores and uses long-lived keys in a secure process complying with the common criteria requirements and it is possible that the error could be related to this service. This service is hosted in the LSA processes and provides key process isolation to private keys and associated cryptographic operations as required by the common criteria. Thus, you need to check this service to see if it’s the one that’s causing the error.
You might also want to try resetting the Trusted Platform Module or TPM to fix the error. You can do this by opening Windows PowerShell and then executing the “Clear-Tpm” command. After that, check if the error is now resolved.
You could also try to create a new User Account on your Windows 10 computer to fix the Windows Hello error. Once you have created a new local user or administrator account in Windows 10, check if you are now able to add the PIN from this newly created user account.
Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.
The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.
The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.
In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:
ping <DNS Server IP address>
If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.
After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:
cscript windowssystem32slmgr.vbs -ato
If the steps above did not work for you, you may want to try the steps found in method 2.
If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.
Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:
slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
After completing the product key change, use the following command to initiate the phone activation wizard, thereby completing the activation of the system:
slui 04
The activation wizard should be able to walk you through the remainder of the process in a step-by-step manner. In addition to appearing as an error code in Windows 10, this particular error may apply to multiple versions of Windows, including:
Steps to address the error code may be different in any of these other versions of Windows. If you have difficulty in resolving the error effectively, seek professional technical help.
