How to Fix Error 421

According to some reports, using RDP or Remote Desktop Protocol on recent versions of Windows 10 results in a black screen. One encounters this issue is when using the Remote Desktop Connection feature on Windows 10. The real causes of this black screen are either the display drivers or some misconfiguration with the Remote Desktop Connection utility. In most cases, the Remote Desktop in Windows 10 will display a black screen and then disconnects afterward. To fix this kind of issue on your Remote Desktop, there are two suggestions you need to check out. First, you can try to disable the persistent bitmap caching, and then you can also try to update your display driver. Follow the given options below for more troubleshooting instructions.

Option 1 – Try to disable Persistent Bitmap caching

The first thing you can do to resolve the black screen issue with the remote desktop is to disable the persistent bitmap caching. All you have to do is follow these steps:

• First, open the Remote Desktop Connection client.
• Next, click on the Show Options button to configure the Remote Desktop Connection.
• After that, go to the Experience tab and uncheck the Persistent bitmap caching option.
• Once done, you should now be able to connect to the remote computer without the black screen.

Option 2 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.

Upgrading your Windows 10 computer does not always go smoothly and you often encounter not just one but various errors so, in this post, we are going to cover several Windows 10 upgrade errors such as 80240020, 8007002C, 80246007, 80070004. All these upgrade errors are related to the Windows Update folder. Thus, you need to clear the Software Distribution folder, repair the System Image and fix System Health in order to resolve all these Windows 10 Upgrade errors. Before you get started on the steps to resolve these tons of errors, you have to disable your security program for the meantime, disconnect your peripherals, remove USBs connected to your PC and then make sure that your PC is connected to the main power supply. Once you have everything covered, carefully follow the options given below.

Option 1 – Delete Windows 10 Update Files in the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, go to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

• Now Open Settings and check for Windows Updates. Windows 10 should begin the download right away.

Option 2 – Try using the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Note: If it happens that the Windows Update client is broken, you need to run the following command to repair it then restart your PC and click on Update once again.

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Note: The Windows Upgrade error, with error code 80240020 is an expected error message that happens when the upgrade requires customer user action. Thus, you need to do the following steps to resolve this particular Windows Upgrade error.

• 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.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdate
• Now right click on WindowsUpdate located in the left pane and then create a new key and name it as “OSUpgrade”
• Next, right-click in an empty space in the left pane and create a new DWORD and name it “AllowOSUpgrade” and enter “1” as its value.

Option 3 – Try running the Windows Update in a Clean Boot State.

Putting your PC in a Clean Boot state can also help you install Windows Updates or Upgrades without any trouble because, during this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

The Windows Subsystem for Linus, also known as WSL, is a useful and excellent tool for developers. However, it isn’t without flaws as users can still encounter some errors when using it. One of these errors is the error code WslRegisterDistribution, 0x8007019e,0x8000000d. Although it seems like the error is have something to do with the installation of WSL, it could be a false positive since some users who’ve installed WSL still encountered the same problem. Here’s the context of the error:

“Installing, this may take a few minutes… WslRegisterDistribution failed with error: 0x8007019e/0x8000000d Error: 0x8007019e/0x8000000d The parameter is incorrect. Press any key to continue.”

Error code 0x8007019e or 0x8000000d could be due to the absence of supporting Windows 10 features since the error does not even let one use the WSL-based command line. If you are one of the users facing this problem, then you’ve come to the right place as this post will provide you with a couple of suggestions to fix it. There are two options you can check out to fix the problem, but before you do that, you need to make sure that the Windows Subsystem for Linux feature is enabled. The two options include enabling WSL using the “Turn Windows features on or off” option and using the Windows PowerShell.

Option 1 – Try to enable the WSL using the “Turn Windows features on or off” option

• To get started, search for “Turn Windows Features on or off” in the Start Search and click on the appropriate result to open a dialog box.
• After that, you will see a populated list in the dialog box and from there, look for the “Windows Subsystem for Linux” option.
• Once you find it, select OK. This will search and install the system files needed and ask you to restart your computer.
• Restart your computer. The Linux distro should now work without any trouble.

Option 2 – Try to use Windows PowerShell

The next thing you can do to fix the error code 0x8007019e or 0x8000000d is to use Windows PowerShell.

• Tap the Win + X keys and click on the “Windows PowerShell (Admin)” option to open Windows PowerShell as admin.
• After that, execute this command to enable the Windows Subsystem for Linux feature: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
• The command you entered will start to search for the required system files and install them.
• If prompted, type “Y” to restart your computer. This should fix the problem.

As you know, the internet has changed the world immensely. Nowadays, JavaScript is pushing the modern web ahead. One of the things that make these experiences with the internet seamless and with less clutter is redirection. It is often used on web pages and there are times when a user is prompted about them and most of the time, we barely notice them. However, there are also instances when things can go wrong with redirects as they could become a loop that could mess things up. And since the browser takes a lot of system resources, redirection can result in a poor user experience. That’s why in this post, you will be guided on how you can stop these automatic redirects on browsers such as Microsoft Edge, Google Chrome, and Mozilla Firefox, on your Windows 10 computer. To get started, refer to each one of the options provided below to stop automatic redirects in Microsoft Edge, Google Chrome, and Mozilla Firefox.

Option 1 – Configure the browsers to stop pop-ups and deceptive contents

There are a lot of browsers with built-in settings that allow users to stop pop-ups and deceptive content. To configure these settings, refer to these steps:

• Microsoft Edge:

  • Click on the three horizontal dots icon or the menu button.
  • Next, click on Settings and select Privacy & Security from the left side navigation.
  • After that, scroll down on the right-side panel and look for Block pop-ups and Windows Defender SmartScreen and then turn their toggle buttons to On.

• Google Chrome:

  • Open Google Chrome and click on the three vertical dots icon for the menu located in the top right corner of the browser.
  • Next, click on Settings and scroll down until you see the Advanced option. Click on it to open the Advanced Settings.
  • Now scroll down until you reach the Privacy and Security section and look for the Safe browsing option and turn its toggle button to On.

  • Finally, scroll down until you reach the Security section and make sure that the checkbox for the Block dangerous and deceptive content is checked.

Option 2 – Try to reset Winsock, TCP/IP & Flush DNS

To stop redirects, you can also reset Winsock and the TCP/IP as well as flush the DNS cache. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 3 – Edit your Hosts File

• Tap the Win + R keys to open then type in %WinDir% and then click OK.

When you have to connect to a drive that’s on a different computer or on external storage, that’s where the mapped network drives come in. Mapped network drives make accessing files a lot easier. However, there are times when it won’t work for some reason. Windows will notify you about the unavailability of mapped network drives in several ways. For one, Windows might display a red X on the network drives or it could be that its status will be unavailable when you try to use it from the Command Prompt or via a notification. It is recommended that you run a few scripts when you log in to your PC as it may so happen that the network drive takes more than usual to connect. Before you start troubleshooting the problem using the given options below, keep in mind that some workouts might only work under certain scenarios. You might need some network access at logon or you might need access to the Group Policy settings. So you need to choose what you prefer more. You can try the given workarounds below if the mapped network drives are not showing or connecting or working on your Windows 10 computer. These workarounds use scripts to make sure that you are connected to them as soon as you start to use your PC. As mentioned, before you can troubleshoot, you need to create scripts first. There are two scripts here namely MapDrives.ps1 which is executed by the second script named MapDrives.cmd and is done at a regular and non-elevated Command Prompt. Follow the steps below to get started.

• You have to create a script file named “MapDrives.cmd” first and then save it on a place where the files are safe. To do that, open a text editor like Notepad and then copy and paste the following script:

PowerShell -Command "Set-ExecutionPolicy -Scope CurrentUser Unrestricted" >> "%TEMP%StartupLog.txt" 2>&1 PowerShell -File "%SystemDrive%ScriptsMapDrives.ps1" >> "%TEMP%StartupLog.txt" 2>&1

• After that, save the file and name it “MapDrives.cmd”.
• Next, create a script file named “MapDrives.ps1” and then copy and paste the following content. Just make sure to save both scripts in the same folder.

$i=3 while($True){     $error.clear()     $MappedDrives = Get-SmbMapping |where -property Status -Value Unavailable -EQ | select LocalPath,RemotePath     foreach( $MappedDrive in $MappedDrives)     {         try {             New-SmbMapping -LocalPath $MappedDrive.LocalPath -RemotePath $MappedDrive.RemotePath -Persistent $True         } catch {             Write-Host "There was an error mapping $MappedDrive.RemotePath to $MappedDrive.LocalPath"         }     }     $i = $i - 1     if($error.Count -eq 0 -Or $i -eq 0) {break}     Start-Sleep -Seconds 30 } Note: Now that you’ve created the script files, it’s time for you to proceed to the options given below.

Option 1 – Try creating a startup item

Note that this option only works on devices that have network access at login. So if it’s not there, the script will fail to reconnect the network drivers automatically. To create a startup item, here’s what you have to do:

• Open the Startup folder located at %ProgramData%MicrosoftWindowsStart MenuProgramsStartUp.
• From there, copy and paste the MapDrives.cmd.
• After that, open the Scripts folder located at %SystemDrive%Scripts copy-paste MapDrives.ps1 and then copy and paste MapDrives.ps1 in there.

Note: After you complete the steps above, a log file named “StartupLog.txt” will be created in the %TEMP% folder. Now all that’s left for you to do is to log out of your computer and then log back in. This will ensure that the mapped drives are open.

Option 2 – Create a scheduled task

It is possible to create a scheduled task that runs as soon as you log in to your computer. To create a scheduled task, follow the steps below.

• You have to copy the MapDrives.ps1 script file to the scripts folder of Windows located at %SystemDrive%Scripts.
• After that, open the Task Scheduler and select Action > Create Task.
• Next, type a name and description of the task in the General tab.
• Then click on the Change User or Group button and select a local user group and click OK.
• Now check the box labeled “Run with highest privileges” and switch to the Triggers tab.
• From there, create a new trigger with the “At Logon” option in the Begin the task drop-down menu and then click OK.
• After that, switch to the Actions tab and create a new action then choose to Start a program.
• Next, type “Powershell.exe” in the Program/Script field, and in the Add arguments (optional) field, type the following:

-windowsstyle hidden -command .MapDrives.ps1 >> %TEMP%StartupLog.txt 2>&1

• And in the Start in the (optional) field, type “%SystemDrive%Scripts” as the location of the script file.
• Now under the Conditions tab, select the “Start only if the following network connection is available” option and then select Any connection and click OK.
• Restart your computer or log off from your account and then log back in so that the task will be executed.

Option 3 – Use the Group Policy settings

You need this option if the mapped network drives are defined via Group Policy settings. You have to update the action of the drive maps to Replace. As a result, it will delete the existing mapped drive and create the mapping on each logon again. However, any settings on the mapped drive that are changed from the Group Policy settings will be gone on each logon. So if the changes don’t work, you need to run the gpupdate command together with the /force parameter in order to refresh the Group Policy setting quickly.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

The latest update from Panos Panay on Twitter is including New and redesigned Snipping tool inside Windows 11. From the shared video, we can see that it includes modern Windows 11 UI redesign and it looks and feels like a part of Windows 11. More things that can be seen from the shared video is that it looks like the new snipping tool is a merged version of the old with snip & sketch. It is good to see that it is still possible to capture screen with easier way natively inside Windows 11 but some more functionality would be more welcome I guess. Users were asking for added functions for a long time like adding simple text for example but from shared video, no new features were presented so for some users 3^rd party solutions will still be the way to go. The new and redesigned Snipping tool will roll out with the next update and we will see then about all new features inside it firsthand. Until then, take care.

The new widget's menu inside Windows 11 is generally met with a positive attitude but there are still users which prefer not to have it. Luckily for them, Microsoft included a very easy way to turn the widgets menu on or off. Follow this easy guide to see how. Right-click on the widget button in the taskbar and click on Hide from Taskbar and that’s it Alternatively, you can also turn it off via the setting app. Go to the settings app and navigate to Personalization > Taskbar > Taskbar Items and flipping the switch beside Widgets to Off. Please note that both methods will only hide the button to toggle widgets menu, at the current state there is no really a way to actually turn it off, only hide it and make it not available to bring it up.
