Microsoft Edge may be about to win a lot of fans by introducing a new feature that it says could prevent one of the most annoying things about being online. A new update to the browser suggests it is looking at a way to block auto-playing videos by default when a user navigates to a website. People spotted a new entry to the Microsoft Edge Canary browser where the company tries out its in-progress updates, that suggests auto-playing videos may have had their day at last. The new addition, for Mac, Windows, and Linux systems, is called “Autoplay Limit Default Setting”, with the description suggesting that Microsoft Edge would set the media autoplay setting to "Limit" as a default - stopping videos from starting up when a user lands on a website. Currently, Edge offers two options for users to control media autoplay - "Allow" (the current default setting), where all videos on a website will play automatically with sound, and "Limit", where media won’t be autoplayed on sites that a user has previously visited. It appears that Microsoft is looking to test the feature in Canary before rolling it out to a wider user base - as blocking autoplaying videos can cause issues for some websites. The same Canary entry also hints at a future "Block" option, which would presumably stop any videos or media from playing when a user lands on a website. However, this feature, which is also listed as being available for Mac, Windows, and Linux systems, doesn't appear to be enabled as yet.

In case you don’t know, a teletype network, also known as Telnet, is a protocol that is meant for internet or LAN communication which is used primarily to control other computers effortlessly. And it is available as a command-line utility in Windows and helps users in opening a command-line interface for the remote computer. However, a lot of users have reported an error that states, “Telnet is not recognized as an internal or external command, operable program, or batch file” when you try to use it. If you are one of these users, then you’ve come to the right place as this post will guide you on how to fix this error in Windows 10. This kind of error means that the Telnet utility is not installed on your computer but Telnet is a default feature in Windows 10 so the protocol mainly is not enabled yet. The Telnet client is disabled by default in Windows 10 and to fix this error, you can try to enable the Telnet Client via Programs and Features or try to install Telnet using an elevated Command Prompt.

Option 1 – Try to enable the Telnet Client via Programs and Features

The first thing you can do is to enable the Telnet client using Programs and Features since it is disabled by default. To do that, follow the steps below.

• Tap the Win + R keys to open the Run dialog box and type “appwiz.cpl” in the field and hit Enter to open the Programs and Features window.
• Next, select the “Turn Windows features on or off” from the options given on the left-hand side.
• After that, look for the Telnet client from the list and check the checkbox next to it and then click on OK to save the changes made.
• Now restart your computer.

Option 2 – Try to install Telnet via an elevated Command Prompt

If enabling the Telnet client using Programs and Features didn’t work, then you can try to do it using Command Prompt instead. To get started, follow the steps given below.

• In the Windows Search bar, type “command prompt” in the field and right-click on Command Prompt from the search results, and select the “Run as administrator” option.
• Next, execute this command to enable the Telnet client: dism /online /Enable-Feature /FeatureName:TelnetClient

Error Code 40 – What is it?

Error Code 40 is a device driver error that users encounter on any Windows 2000 and later operating systems. It occurs when the peripheral device that you connect to your PC cannot be accessed due to a change in the system registry.

This is due to the presence of invalid sub-keys of the device driver in the system registry. It is a common error that users come across and appears on your PC with either of the following messages:

“Information in the registry entry for this driver is invalid”

OR

"Windows cannot access this hardware because its service key information in the registry is missing or recorded incorrectly. (Code 40)"

Solution

Error Causes

As mentioned above, the error code is triggered when the device driver’s invalid sub-keys appear in the registry, effectively changing it. This happens when the windows system files get damaged due to the following factors:

• An incomplete program uninstallation
• An incomplete program installation
• Hardware is not removed properly
• System recovery from viruses
• An improper system shut down

Factors such as incomplete installations or uninstallations or an improper system shut down can cause files to become damaged that threaten the health of your computer.

Removing viruses from the computer is also another factor as it removes the entries in the Windows system files which contain the viruses including spyware or malware

Further Information and Manual Repair

Fixing Error Code 40 is similar to fixing other device manager error codes. Here are a few methods you can try.

Method 1 – Use System Restore

You can use system restore to eliminate the problem. Here is how you can use it:

• Log in using an Administrator account
• Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
• Click ‘Restore my computer to an earlier time’ and click ‘Next’
• Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
• Click ‘Next’ on the confirmation window to proceed
• Restart your PC after restoration is complete

By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system registry files that can help avert the error code.

Method 2 – Manually uninstall then reinstall the device driver

If using system restore also does not work in removing the error code, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.

This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what contributes to the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.

You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC. Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’.

Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 3 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick, however, it may be time-consuming especially when you would have to resort to your hardware user manual.

Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

It further ensures that your drivers are installed in their entirety leaving no room for any incomplete files to remain that create Error Code 40.

It also has the added advantage of being able to backup and restores your files should there be the slightest possibility of system file damage.

Thus, registry damage can be averted by letting the software roll back the system files to an earlier healthy checkpoint. Driver Assist is the answer to fixing your PC error codes accurately and quickly.

We are all waiting for the release of Intel’s Alder Lake series of processors and real-world results on its performance. Sadly lately it came to our attention that some games might have issues with the processor. Now before you go on the bandwagon on bashing Intel itself take note that it is not Intel’s fault at all. The issue that arises is mostly due to DRM software and how it works. As you might know or not, Alder Lake has two sets of cores, standard performance cores, and power cores, and with Intel’s Thread Director on-chip right cores will be used for the right tasks, and here lies the issue. DRM software might detect Thread Director as something suspicious and malicious, and then cut access to the game because of this. Intel, of course, has reached DRM manufacturers and places documentation about how software should be developed with this hybrid technology in mind. Of course, newer games will be updated if needed and everything will work fine, also games on GOG will work fine because of GOG’s policy of no DRM store but some older ones might be left in limbo. They could work fine but DRM might be triggered and prevent them from loading, usually, game developer itself removes DRM protection after some time but that is not really always the case and there is a chance that some games might simply just not work on Alder Lake CPU only because of DRM protection.

Conclusion

I will admit that I have not been a great fan of DRM in general, I understand that game developer want to protect themselves from piracy but how it looks they were not really successful with it. Even today single-player games get pirated on the day they are released and legally bought ones always make trouble for people that actually paid for them. I remember times when DRM was awful and you could install a game a limited number of times, luckily this was removed but it seems that many old habits still remain sadly and DRM is present even today in various forms. GOG is proof that people will buy DRM-free games and that they will support this kind of model. Maybe it is time to forget about fighting against piracy, you will not make it go away and people who do not want to buy games will not buy them, on other hand many users that do buy games, if they cannot use them they will rest to pirated version since that one will work. It is sad to see that pirated software can work better than a legal one and offer a more pleasant experience.
