Disable Speech Recognition feature in Windows
Speech Recognition is a technology used to control computers using voice commands. Through this feature, you can say commands that your computer will respond to, and aside from that, you can also dictate text to your computer which eliminates the need to type words in any word processing program or text editor. All in all, the Speech Recognition feature allows you to communicate with your computer and improves your computer’s ability to understand your own voice better as well as improve its diction accuracy. However, before you can improve its accuracy, you need to “train the feature” first. And if so far you are not satisfied with its performance, you actually have the option to disable it. So in this post, you will be guided on how you can disable the Speech Recognition feature in Windows 10 v1809.

To disable Speech Recognition on your computer, follow the steps below.

Step 1: Go to Settings > Ease of Access. Step 2: From there, go to Speech. Step 3: Now switch off the toggle button for Speech Recognition to disable this feature. On the other hand, you can also disable the Online Speech Recognition feature if you really don’t want to have anything to do with it. You have two options to do that – you can either do it using Settings or using the Registry Editor.

Disable Online Speech Recognition feature via Settings:

  • Click on the Start button and select Settings.
  • Next, go to the Privacy section and click on the Speech option located at the right pane.
  • Then switch the toggle button off to turn off the Online Speech Recognition feature.
Note: Speech services exist on your computer and even in the cloud since Microsoft collects essential information from these services in order to enhance user experience and if you want to stop this, you have to turn off the “Getting to know you” option under the “Inking and typing Personalization” section.

Disable Online Speech Recognition feature via Registry Editor:

Before you proceed, you need to create a System Restore Point first.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to the following registry path:
HKEY_CURRENT_USERSoftwareMicrosoftSpeech_OneCoreSettingsOnlineSpeechPrivacy
  • After that, check the default value of the “HasAccepted” key located in the right pane. As you can see its value is set to “1” which means that the Speech Recognition feature is enabled. And so to change it, you have to set “0” as its new value to permanently disable the feature.
  • Just double click on the key and change the value from “1” to “0”. Keep in mind that even if you are using a 64-bit Windows 10 computer, you still have to create a 32-bit DWORD value.
  • After that, restart your computer to apply the changes made.

Solution

Restoro box imageError Causes

Error code 0x80070490 might appear for various reasons but is most prominent in the following cases:

  • Attempts to install Windows 8 or 8.1
  • A corrupted Component-Based Servicing (CBS)

Further Information and Manual Repair

The solutions for error code 0x80070490 vary so users may need to attempt each solution to find the best results.

  1. Repair Corrupted Windows Files with System File Checker

The System File Checker (SFC.exe) is a Windows-based utility that enables users to check and repair corrupted or damaged system files. It can also restore missing systems files which can be the cause of errors such as error code 0x80070490.

To repair files, begin scan by swiping the right edge of the screen then opening the search box. Type Command Prompt, right-click this option, then select Run as Administrator. Once the scan begins, wait for the process to be completed then restart your device. Check if the error is resolved by reattempting updates. If error code 0x80070490 in Windows 8 or 8.1 persists on your device, proceed to the solution below.

  1. Perform Clean Boot

A clean boot is one of the best ways to reduce conflict among files – an issue that may arise whenever users update, install or run programs on their Windows device.

To run a clean boot, your device reboots using limited drives and programs. The process allows you to identify which conflict among programs is causing errors on your Windows device.

You can access the clean boot tool by entering msconfig in the search box. Select Services, then System Configuration. Check the Hide all Microsoft services checkbox then select Disable all. Next, go to the Startup tab, click and open Task Manager. After selecting the Startup tab, make sure you right-click each startup program. Click Disable from the context menu then close Task Manager when done. Select OK on the System Configuration menu then restart your machine to clean boot Windows 8 or 8.1.

If the clean boot successfully identifies and resolves issues with corrupted files, you will be able to access updates using Windows Update or Microsoft Update. Error code 0x80070490 will no longer occur. But if that proves unsuccessful, other options are available below including running Windows Update Troubleshooter.

  1. Run Windows Update Troubleshooter

This method can provide a simple solution for users as it verifies whether your Internet connection, network adapter and Windows Update services are functioning properly. However, if you are uncertain as to whether you will be able to troubleshoot, seek assistance from a qualified Microsoft technician.

To run Windows Update Troubleshooter, simply download from Microsoft’s website. Be sure you are downloading the tool recommended for your operating system, in this case Windows 8 or 8.1. After you download Windows Update Troubleshooter, run it to enable the tool to check for and resolve update issues on your device.

  1. Use DSIM or System Update Readiness Tool

The System Readiness Tool or DSIM is another method you can use to correct issues related to error code 0x80070490. This tool checks problems on your system that might prevent your computer from performing Windows updates including issues related to damaged system files.

Once you download and install this tool, it will be able to run automatically. The process may be technical, however, requiring specialized knowledge to successfully download and run the tool. Consider getting assistance from an IT professional in this case. Also, check Microsoft's online resources to download the tool.

  1. Use an Automated Tool

Having an automated tool at hand will enable users to always be prepared. Download a powerful automated utility tool to provide solutions whenever error codes or other problems affect your Windows 8 device.

Fix Hello Errors 0x801c004d or 0x80070490
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:
  • 0x801c004d – Unable to enroll a device to use a PIN for login”
  • 0x80070490 - Not recognized, Pin and fingerprint are no longer options for signing in”
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.

Option 1 – Try checking for any available Windows Updates

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.

Option 2 – Try creating the PIN again

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.
  • Remove the PIN by going to Settings > Accounts > Sign-in options.
  • From there, go to the PIN section and click on the Remove button.
  • You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
  • Restart your computer and then set up a new PIN.
  • Once you’re done, restart your computer and check if the error is gone now.

Option 3 – Try checking the CNG Key Isolation Service

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.
  • Tap the Win + R keys to open the Run dialog box and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
  • Next, locate the “CNG Key Isolation Service” and once you find it, double click on it to open its Properties box.
  • After opening its Properties, check its Startup type and select Manual. This is the default setting and if it is Disabled, then it’s no wonder why you’re getting errors with Windows Hello, thus, you need to enable it.
  • Once done, restart your computer and check if you can now add the PIN to Windows Hello. If you still get the error, then you might want to try setting the CNG Key Isolation Service from Manual to Automatic and then click on the Start button and see if it fixes the error or not.

Option 4 – Try to reset the Trusted Platform Module or TPM

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.

Option 5 – Try to create a new User Account

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.
