Razer new table concept looks futuristic

Hello and welcome everyone, just a few years ago we had FLASH video content on the internet, we had FLASH games, full FLASH website experiences, and more, but then flash was shut down mostly due to security reasons meaning that in just a few months we have lost most of FLASH web content. However, there is still FLASH content on the internet even today, there are still FLASH videos and flash games, but we can not play any of that content since browsers do not support FLASH and you can not get the FLASH plugin for browsers. So what might be the solution for this situation?

Ruffle and FLASH emulation

Emulation of course. We will not be able to get the flash player working, well at least not the original and official one, but we can make flash content playable again inside our browsers. The first thing is first, we need to get an emulator package from the internet in order for this trick to work, one we will be using is RUFFLE. It is lightweight, it is free, it is open source and it is reliable, everything we need. Download RUFFLE from its official website here. For Chrome and Edge download the ZIP package, for Firefox, go to the Firefox section of the tutorial. There is also a desktop version of RUFFLE there so if you are keen on playing your flash content on your desktop computer you might well grab that as well, but for the sake of this tutorial where we are enabling flash in our browsers, we will not focus on that part since it is pretty straightforward. Now once you have downloaded the RUFFLE emulator, please extract it to the desired folder somewhere on your computer. Once it is extracted, start your browser of choice and follow instructions.

FOR CHROME:

1. Navigate to: chrome://extensions/
2. Turn ON developer mode in the top right corner
3. Click on Load unpacked
4. Navigate to the folder where you have extracted RUFFLE

FOR EDGE:

1. Navigate to: edge://extensions/
2. Turn ON developer mode on the bottom left corner
3. Navigate to the folder where you have extracted RUFFLE
4. Turn RUFFLE ON

FOR FIREFOX:

1. Go to the RUFFLE download page, we can not use the zip package we were using for Chrome and Edge
2. Right-click on the Firefox download link
3. Save link by clicking on Save link as...
4. Navigate to about: debugging
5. Click on this Firefox
6. Click Load Temporary Add-on
7. Select the .xpi that you have downloaded

BONUS:

If you want to enable FLASH content live on your website use:  <script src="path_to_ruffle/ruffle.js"></script>

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.

DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files. In this post, we will be discussing one DLL file called ntdll.dll. It is described as “NT Layer DLL” which means that it contains some Kernel functions that help in the normal functioning of the Windows operating system. It is created by Windows in the System32 folder when the OS gets installed. This file can serve different programs simultaneously by providing them with different Kernel functions which support the programs’ performance. However, if you encounter the ntdll.dll file error on your Windows 10 computer, read on as this post will guide you in fixing the problem.

Option 1 – Try to re-register the ntdll.dll file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

The error code 0X8019019A is shown when a user fails to add his Yahoo account to the Mail app due to the outdated or corrupt installation of the Mail app. Not using an App-specific but a normal Yahoo account password may also result in the error at hand. In this guide, we will show you how to effectively fix this error so you can set up Yahoo mail.

1. Reboot PC

   Perform a restart of your system to rule out a temporary glitch in the system. Also, check if you can successfully access your email through a web browser using the same credentials as you are using with the Mail app. Additionally, make sure that no VPN or proxy server is being used to access the internet (VPN/proxy may work fine with the web version of Yahoo mail but may hinder the access through a mail client).

2. Update Windows and the Mail App to the Latest Build

   If your system is not updated to the latest build it can create incompatibility between the OS modules. Updating the Windows and Mail app of your system to the latest build may solve the problem.

3. Re-add the Yahoo Account to the Mail App

   The Yahoo account issue could be a result of a temporary glitch in the communication modules of the system. The glitch may get cleared if you remove and then re-add the Yahoo account to the Mail app.

4. Reset the Mail App to the Defaults

   You may fail to add the Yahoo account to the Mail app if the installation of Mail itself is corrupt. In this scenario, resetting the Mail app to the defaults may solve the problem.

5. Generate an App Password and Use it to Add the Yahoo Account to the Mail App

   Yahoo has implemented tons of security features to its accounts. One such feature is the use of app-specific passwords for less secure apps like the Mail app. If your Yahoo username or password is not working with the Mail app, then using the App-specific password may solve the problem.

Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. On the settings screen, choose Apps. When the Apps screen opens on the left click on Default apps. On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.
