Turn On or Off the Recommended Troubleshooting
For a while now, Microsoft has been working hard to add various built-in troubleshooters in Windows 10. In fact, there is a troubleshooter for almost every standard or common error in Windows 10. And now with the newly released Windows 10 v1903, Microsoft has added the Recommended Troubleshooting which allows Windows 10 to automatically fix a lot of critical issues on your computer, and in this post, you will be guided on how you can turn on or off the Recommended Troubleshooting in Windows 10. The Microsoft Diagnostic & Feedback data only provides two settings – Basic and Full. So if you want to turn off the Recommended Troubleshooting for some reason, the only way to do so is to stop it from collecting complete data from your PC. And to turn it on or off, you can choose to switch between them. To do that, navigate to Settings > Privacy > Diagnostics & feedback and from there, select Basic under the Diagnostic Data section. After that, go back to Settings and go to Update & security > Troubleshoot. Once you’re there, you should see a warning message saying, “Share Full Diagnostic data to get additional troubleshooting recommendations”. Based on the message, Microsoft will only offer the recommended troubleshooting based on the Full Diagnostic data which it collects from your computer. On the other hand, if you know how to navigate and use the Windows Registry, then you can enable or disable the Recommended Troubleshooting via Registry Editor but before you proceed, make sure that you create a System Restore point. Once that’s covered, follow these steps:
  • Tap the Win + R keys to open the Run dialog box and type “regedit” in the field and tap Enter to open the Registry Editor.
  • Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoft
  • From there, look for the key named “WindowsMigration”. If you can’t find it, just right-click on the left pane and create a new key and then name it “WindowsMigration”.
  • After that, create a DWORD “UserPreference” and double click on it to set its value to “0” if you want to turn it off or “1” if you want to turn it on.
  • Exit the Registry Editor and restart your computer to apply the changes made.
Note: The Recommended Troubleshooting functionality can look into the error logs sent back to the Microsoft team and use an algorithm to set up a solution for you and they’re nothing but Diagnostics and Feedback data that Windows collects and sends back to Microsoft. Moreover, the recommendations are only visible if you are connected to the internet, else it will show the same message.

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.

It could be that your monitor has these buttons without you knowing and you suddenly pressed them by mistake which caused your screen to rotate. Thus, you have to check your monitor for any physical buttons on the side and if you see a menu, navigate to its options and check if there are screen rotation options. To make it easier for you, you can simply search your monitor’s model online and see if these buttons exist.

Should you use the Faraday bag

Faraday bag is a new take on security and privacy for people using a lot of electronic devices and credit cards. So what is exactly a Faraday bag?

faraday bag

Faraday bag explained

Faraday bag is designed in the same manner as the Faraday cage which was invented by Michael Faraday, who was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism, and electrolysis.

The idea of the Faraday cage is that anything inside a cage that is made of specific grid size is completely isolated from outside current and magnetic fields since the cage itself will pick up everything upon itself. This means that for example, a human could be inside a cage that is struck by lightning and be perfectly safe and fine.

This idea led to the Faraday bag design, which takes this concept and places a wiring pattern inside clothing in order to isolate all magnetic fields from the outside so your devices and cards are completely cut off from any kind of influence and electromagnetic waves. If the pattern and quality of material for the bag are good, you have a fully safe placeholder for your stuff.

Advantages of Faraday bag

The main advantages, of course, are the privacy and safety of mobile phones and credit cards from outside influences and this is why this bag has been designed in the first place. If the bag is designed properly your phone would not be able to be hacked nor accessed from any outside source, GPS tracking will also be disabled and your phone location will not be visible. Credit cards will also be completely safe from any malicious attack via wi-fi signals.

Disadvantages of bag

Well, the disadvantage of using this bag is a very simple one, since your phone is isolated from outside influence that will also mean that you will not be able to take messages or calls on it while it is in the bag. Notifications from the internet would also be disabled so it is security vs usability deal.
