How to Fix Error 421

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.

Recently, a number of Windows 10 users reported an issue wherein they try to print from their PCs but were unable to and got an error message instead that states, “Port in use, please wait”. However, no matter how long they waited, nothing changed and they were still unable to print from their computers. On the other hand, when some of the users attempted to print wirelessly from their mobile devices, the printing continues which indicates that there is some issue between the computer and the printer. So if you are one of the users who are currently facing this problem, then this post should help. To fix this issue with your Printer, here are some possible fixes you can try that might work.

Option 1 – Run the Printer Troubleshooter

The first thing you can do to fix the “Port in use, please wait” error is to run the Printer Troubleshooter. This built-in troubleshooter in Windows 10 can help you fix most print issues. It checks if you have the latest printer drivers and then tries to fix and update them automatically. Aside from that, it also checks if you have connectivity issues or if the Print Spooler and the required Services are running fine. To run it, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the USB Composite Device option and right-click on it, and select the Update Driver from the options.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try selecting the correct port for your Printer

If the first two options given above didn’t work, then maybe it’s time to select a correct port for your printer since the wrong port has been selected which is why you’re getting the “Port in use, please wait” error.

• Open “Devices and Printers” from the Start search.
• Next, look for your printer from the list of devices and right-click on it, and then select Printer Properties.
• Now go to the Ports tab under the newly opened Properties window and make sure that the port type matches the connection on the list of ports currently in use.

Note: If your printer is using a USB connection then the port should have a USB or DOT 4 in its description but if your printer is using a network connection then it should have the following description:

• WSD
• Network
• IP

And if you notice that there are several listings for the same type of port, you have to change the selection to a different one and then click the OK button to save the changes made.

USB Kill, a USB device is able to fry and damage your computer, mobile phone, router, etc. This device is quite dangerous and can kill electronics the moment it is inserted into an available port. By now people should know that they should not put unknown USB sticks into their devices because of potential virus and malware threats but this raises using unknown sticks to a whole new level.

Kill kits are not really new to the market, they have existed before but lately, technology really progressed and the latest USB sticks are really good, their success rate is around 95% which is pretty high and should not be taken lightly.

The second thing that you really should not play with strange USB sticks is that they dropped in price really hard, although top Kill kits will still go as high as around 300 USD, there are really cheap ones lurking in Ali Express that are just 6 USD!!! that makes them affordable devices for the mass market.

The device is made to take energy and current from the port it is plugged in, multiply it and release its charge back into the device, successfully frying some components immediately. Some more professional Kill sticks can even fry devices even when the device itself is not powered and can be even started remotely.

The point of this article is to make you aware that you should not in any kind of circumstances use and plug-in USB sticks into your devices that you do not know where they come from, especially from the mail!!

Following a two-year investigation by the California Department of Fair Employment and Housing, the state has filed a lawsuit against Activision Blizzard for fostering a "frat boy" culture in which female employees are allegedly subjected to unequal pay and sexual harassment. As reported by Bloomberg, Activision Blizzard is being accused by the state of California of discriminating against female employees at nearly all levels of employment, including in regards to compensation, promotion, assignments, and termination. The state alleges Activision Blizzard’s leadership has failed to address any of these outstanding issues or prevent them from occurring within the workplace. You can read the full details of the lawsuit here. The suit, filed Tuesday in the Los Angeles Superior Court, says Activision Blizzard, which is made up of about 20 percent women, assigns women, and women of color, to "lower paid and lower opportunity levels" with lower starting pay for similar work as their male counterparts. The documents also accuse Activision Blizzard of fostering a "pervasive 'frat boy' workplace culture in the office. Male employees are said to drink "copious amounts of alcohol" as they make their way through cubicles and "often engage in inappropriate behavior toward female employees." Male employees are said to come to work hungover, play video games during work "while delegating their responsibilities to female employees, engage in banter about their sexual encounters, talk openly about female bodies, and joke about rape." The lawsuit also cites one particular incident where a female employee, who was already subjected to intense sexual harassment at the company, committed suicide during a work trip with a male supervisor who allegedly brought inappropriate, sexual items with him on the trip. The lawsuit is asking for an injunction that will force Activision Blizzard to comply with workplace protections, as well as deliver unpaid wages, pay adjustments, back pay, and lost wages and benefits for female employees.

An Activision Blizzard spokesperson sent the following statement in response to the allegations:

We value diversity and strive to foster a workplace that offers inclusivity for everyone. There is no place in our company or industry, or any industry, for sexual misconduct or harassment of any kind. We take every allegation seriously and investigate all claims. In cases related to misconduct, the action was taken to address the issue. The DFEH includes distorted, and in many cases false, descriptions of Blizzard’s past. We have been extremely cooperative with the DFEH throughout their investigation, including providing them with extensive data and ample documentation, but they refused to inform us what issues they perceived. They were required by law to adequately investigate and to have good faith discussions with us to better understand and to resolve any claims or concerns before going to litigation, but they failed to do so. Instead, they rushed to file an inaccurate complaint, as we will demonstrate in court. We are sickened by the reprehensible conduct of the DFEH to drag into the complaint the tragic suicide of an employee whose passing has no bearing whatsoever on this case and with no regard for her grieving family. While we find this behavior to be disgraceful and unprofessional, it is, unfortunately, an example of how they have conducted themselves throughout the course of their investigation. It is this type of irresponsible behavior from unaccountable State bureaucrats that are driving many of the State’s best businesses out of California. The picture the DFEH paints is not the Blizzard workplace of today. Over the past several years and continuing since the initial investigation started, we’ve made significant changes to address company culture and reflect more diversity within our leadership teams. We’ve updated our Code of Conduct to emphasize a strict non-retaliation focus, amplified internal programs and channels for employees to report violations, including the “ASK List” with a confidential integrity hotline, and introduced an Employee Relations team dedicated to investigating employee concerns. We have strengthened our commitment to diversity, equity, and inclusion and combined our Employee Networks at a global level, to provide additional support. Employees must also undergo regular anti-harassment training and have done so for many years. We put tremendous effort into creating fair and rewarding compensation packages and policies that reflect our culture and business, and we strive to pay all employees fairly for equal or substantially similar work. We take a variety of proactive steps to ensure that pay is driven by non-discriminatory factors. For example, we reward and compensate employees based on their performance, and we conduct extensive anti-discrimination training including for those who are part of the compensation process. We are confident in our ability to demonstrate our practices as an equal opportunity employer that fosters a supportive, diverse, and inclusive workplace for our people, and we are committed to continuing this effort in the years to come. It is a shame that the DFEH did not want to engage with us on what they thought they were seeing in their investigation.

Conclusion

We will see how things work out, but I am not too optimistic for Activision Blizzard, truth to be told these reports are really bringing up some disturbing news on the sunlight. I just hope that all responsible will be brought to justice.

After you fresh install Windows 10 on your computer, it allows you to set up a PIN just before you can start using it. However, a number of users reported that the Windows 10 installation gets stuck on the “Set up a Pin” phase. If you are one of the users who experience the same thing, then read on as this post will walk you through fixing the problem. As users start to use their newly installed Windows 10 computer, they reported that the screen is still stuck even after they enter the correct PIN twice and there is no way for them to go forward or backward. Note that this is a part of the account setup and that your computer must stay connected to your internet connection before you finalize everything. And even though the PIN works when the computer is offline, the account setup still needs an internet connection, at least for a fresh installation. The solution for this kind of issue is quite easy and there won’t be any problem even if your computer shuts down or restarts since the installation is already complete and all that’s left is the account setup. To fix this problem, follow the steps given below. Step 1: The first thing you have to do is to turn off your internet connection or disable all connectivity from your computer. Note: If you are using either an Ethernet cable or a Wi-Fi switch to connect to the internet, you have to disable or remove them. But if you don’t have any options, just completely turn off your internet connection. Step 2: The next thing you have to do is to force your computer to shut down and then restart your computer. The setup process will eventually pick up exactly where it left off. The only difference is that there is no connection to the internet and your screen will no longer be stuck on the PIN setup screen so you now have the option to skip it and wait until you’re logged in for the first time. Step 3: Once you’re done, you can then you can choose to Setup Pin later on and turn your internet connection back on or connect your computer with an internet connection.

One of the selling points of Windows 11 was the ability to run Android apps natively in it without the need for any third-party software. It is not a big surprise that even after its release Microsoft is evolving and expanding Windows 11 and its features.

Microsoft is now rolling out an update for the Windows Subsystem for Android on the Dev Channel of the Windows Insiders program. The new version upgrades the core operating system from Android 11 to Android 12.1 (also known as Android 12L), which means the new system and app features in Android 12 and 12.1 are now available on Windows for the first time. However, not the new features in those updates apply to the modified version that runs on top of Windows. For example, one of the main improvements in 12.1 was a dual-pane notification panel for larger screens, but Android app notifications on Windows just show up in the Windows notification panel.

The upgrade also improves how Android apps integrate into Windows. The Windows taskbar will now show which Android apps are currently using the microphone, location, and other system services — similar to many native Windows applications. Toasts messages (the small popups that some apps use for temporary messages) are now displayed as Windows notifications, and the titlebar on Android apps will use the current activity name for the title.

Full changelog

• Windows Subsystem for Android updated to Android 12.1
• Advanced networking on by default for newer x64 Windows builds
• Updated Windows Subsystem for Android Settings app: redesigned UX and diagnostics data viewer added
• Simpleperf CPU profiler recording now works with Windows Subsystem for Android
• Windows taskbar now shows which Android apps are using microphone and location
• Improvements to Android app notifications appearing as Windows notifications
• Reduced flicker when apps are restored from minimized state
• Apps are not restarted when devices come out of connected standby on recent Windows builds
• New video hardware decoding (VP8 and VP9)
• Fixes for on-screen keyboard in apps
• Fixes for full-screen Android apps and auto-hidden Windows taskbar
• Windows Subsystem for Android updated with Chromium WebView 100
• Added support for Android NetworkLocationProvider in addition to GpsLocationProvider
• Improved general stability, performance, and reliability

The new update is limited to Windows Insiders for now, but once Microsoft fixes all the bugs, it should start rolling out to everyone on Windows 11 that has the Android Subsystem enabled.

We have all been there, unfortunately, the application freezes, and sometimes it can even freeze whole windows. Well if the whole Windows freezes because of the application there is not much we can do except hard reset but if only the application freezes we can still kill it and return the PC in working condition. The first thing you can try is to press ALT + F4, this shortcut is for closing the program, if the application is frozen Windows will try to close it when using this shortcut, and if it succeeds you will find yourself on the desktop environment in Windows with non-responsive application taken care of. If however, this fails and the application is not closed, try ending it in the task manager. To open task manager press CTRL + SHIFT + ESC, locate unresponsive application select it, and click on the end task button on the bottom right.

Sticky Notes is one of the useful programs and in the early days, the option is available for users to change the font size of the text a lot easier. However, for some unknown reason, Microsoft decided to get rid of this feature in the latest Windows Update. One would expect that the feature will be replaced by an even more useful feature but it’s not which makes the Sticky Notes app worse than before. Worry not though for it doesn’t have to stay that way as there is another thing you can try to change the font size in your Sticky Notes app and that’s what we’re going to cover in this post. As mentioned, Microsoft removing this font feature is quite strange and in the past, users asked for this feature and since it’s no longer available, you can try following the steps given below to bring it back. And for that, you need to go to the Ease of Access section in the Settings app. Refer to the steps given below for more instructions. Step 1: First, tap the Win + I keys to open Settings and then go to the Ease of Access section. Step 2: After going to the Ease of Access menu and select Display from the list of options. Step 3: From there, you should see an option that says “Make text bigger”. And then use your mouse to navigate to the slider to change the size of the font. Note: Take note that after doing all the steps above, it will change not just the Sticky Notes app but also everything in Windows 10. This method is actually the best since it only changes the size of the apps rather than a wholesale change in your Windows 10 computer. Step 4: Next, scroll under Display until you see the “Change the size of apps and text on the main display” option where you’ll see that the option is 100% but you’ll want to change that to 125%. Step 5: After that, click on the drop-down menu and select 125% and then restart your Windows 10 computer. Step 6: Now open the Sticky Notes app and check if you can now change the font size in the Sticky Notes app.

There are various complex tasks that take place under the hood while you upgrade or clean install the Windows operating system on a computer. Because of its complexity, there are times when you might encounter some errors when you upgrade or clean install Windows 10. One of the errors you could encounter is the error that states, “Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation”. This error does not only occur in Windows 10 as it could also occur on the other versions of Windows. There are a lot of possible causes for this error. It could be due to incompatible BIOS, corrupted system files, improper installation media or it could also be due to excessive hardware plugged into your computer and so on. Whatever the cause is, here are some potential fixes you need to check out to fix the problem.

Option 1 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the error.

Option 2 – Try to update the BIOS

As you know, the BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version in your computer.
• Now restart your computer to apply the changes made.

Option 3 – Try to reconfigure all the created partitions

You could also try to reconfigure the partitions by deleting and recreating all the available partitions on your computer and then see if it fixes the problem.

Option 4 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

One of the popular tools that allow a user to offer or obtain remote assistance on a computer is the TeamViewer. It is available on all the major computer and mobile platforms which makes it a lot useful to every kind of user, even on the go. If you are one of the users who frequently use TeamViewer, then you must be familiar with this one sentence that states, “Initializing display parameters”. In common cases, this sentence will appear for a second and load the other user’s screen. However, some users reported that TeamViewer gets stuck on that stage and did not move ahead even a bit. If you experience the same problem, read on as this post will guide you in fixing this issue with TeamViewer on your Windows 10 computer. At the time of writing, the cause of this issue is still unclear. It could be due to the quality of internet connection, conflicts in process, misconfiguration of Remote Access, and many more. To fix this issue, you can try to update TeamViewer for both the users or have it reinstalled with Unattended Remote Access, or reconfigure the Remote Access. You can also try to kill any conflicting processes or optimize your internet connection. For more details, refer to the given options below.

Option 1 – Reboot your router

The first thing you can try to do to fix the error is to simply restart your router. All you need to do is reboot the router from its Admin panel or you can also turn it off manually and turn it back on after a couple of seconds so that it can completely reboot. Once you’re done, try accessing your server again and see if the error is now fixed.

Option 2 – Try to update TeamViewer on both users’ end

You might have to update the TeamViewer on both ends and to do that, you need to start the TeamViewer installer again. Once it is installed, run the program and click on the Help option in the Menu ribbon and then select the “Check for updates…” option. If an update is found, you will be notified within a couple of seconds through a pop-up mini window. From there, click on Update and then follow the next onscreen instructions that appear and choose your TeamViewer version to update.

Option 3 – Try reinstalling TeamViewer via the Unattended Remote Access

If the first two given options didn’t work, you might have to reinstall TeamViewer from the Windows 10 Settings app or Control Panel.

• Tap the Win + R keys to launch the Run utility and type “regedit” in the field and hit Enter to open the Registry Editor.
• Here, navigate to this registry key: Computer HKEY_LOCAL_MACHINE SOFTWARE Wow6432Node TeamViewer
• Next, look for the TeamViewer key and right-click on it, and select Delete.
• After that, restart your PC to apply the changes made and then start TeamViewer again, and then click on Connection > Open Management Console.
• Then sign in or sign up to get registered and select the Add new device radio button under Add > Add computer located on the top-right corner and then select the Download now option.
• Now follow the next onscreen instructions that appear to complete the installation and then check if it fixes the problem or not.

Option 4 – Try reconfiguring the Remote Access

You can also try to reconfigure Remote Access in case there is some misconfiguration that might have caused the problem with TeamViewer.

• On your Desktop, right-click on This PC and click on Properties.
• Next, go to the left side of the navigation panel and click on Remote Settings.
• From there, make sure that the “Allow Remote Assistance Connections to this computer” checkbox is checked under the Remote Assistance section.
• Once done, click on the Advanced button. This will open a new mini window where you’ll have to check the “Allow this computer to be controlled remotely” option under the Remote Control section.
• Then click on OK and see if it fixed the problem.

Option 5 – Try to kill any conflicting processes

• Tap the Ctrl + Shift + Esc key combination to open the Task Manager.
• Then navigate to the Processes tab and right-click on the BGInfo process.
• Now select the End Task option to kill its process and then start TeamViewer again and check if the problem is resolved.

Option 6 – Try to optimize the quality of connection

You need to take care of two things under this option – first, you have to disable the loading of the Wallpaper of the computer which is the one that you’re trying to access remotely. To do that, you have to select the Extras menu from the menu ribbon and then select Options. And under the Remote Control section, check the “Remove remote wallpaper” option. The next thing you have to do is to optimize the quality for the speed by selecting the “Optimize Speed” for the menu of Quality still under the Remote Control section.
