Recently, a number of users reported that they were not able to run PLEX and other similar streaming services ever since a Windows Update was automatically installed in the system. The error in these streaming services has something to do with a missing Mfplat.dll DLL file from the Windows Media Feature Pack. On the other hand, some users also reported that the mfplat.dll error occurred on several games as well which used the Media Feature Pack. Usually, the mfplat.dll error is caused by the missing Media Feature Pack in Windows 10. Although most of the time the Media Feature Pack is installed by the application that needs it or through Windows Update automatically, there are just certain installers that do not have it. It could be that the Media Playback service was disabled by a particular Windows Update. Aside from that, the error might be because your computer is using Windows 10 N – a Windows 10 version that does not include the Media Feature Pack by default. Whatever the cause may be, you can troubleshoot the problem with the help of the options given below. But before you go on, keep in mind that downloading the missing DLL file and copying it to the folder of the program where you encounter the error won’t really help and will only make things even more complicated.

Option 1 – Install the Media Feature Pack for Windows 10 N version

As mentioned, the Windows 10 N version does not come with Windows Media Player. Meaning to say, the Media Feature Pack is also not installed by default or won’t be updated by the Windows Update component. So if you are not quite sure what Windows 10 version you currently have installed, refer to these steps:

• Tap the Windows key + S and then type “about” in the search box.
• From the search results, click on the “About your PC” to open the About tab of the Settings app.
• Afterward, scroll down to the Windows specifications and check your Windows version under Edition.

Note: If you’ve determined that your computer is using the Windows 10 N version, you need to install the appropriate Media Feature Pack for your computer. How? Refer to the steps below:

• Click this link to download and install the Media Feature Pack from Microsoft’s official website.
• Upon installation, select the edition you want to install using the drop-down menu and then click on Confirm. Take note that there are few reasons why you’d want to install the older version since most streaming services like PLEX and most games usually require version 1803.
• After that, wait until the request is validated. The download should begin in a few minutes automatically.
• Once the download is completed, open the installation executable file and follow the next on-screen instructions to install the Media Feature Pack on your computer.
• Restart your computer. After your computer has rebooted, open the application where you’re getting the mfplat.dll missing error and then check if the problem is now fixed.

Option 2 – Enable Media Playback via Command Prompt

If you encounter the mfplat.dll missing error when you attempt to run PLEX or other similar streaming service and you’ve already verified that the Media Feature Pack is indeed installed, you might want to try enabling it using an elevated Command Prompt. There are cases when a particular Windows Update ends up disabling the feature and creates the grounds which results in the mfplat.dll missing error. Thus, you can have to enable the feature via Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• Next, click on Yes if a User Account Control prompt pops up.
• After opening Command Prompt, copy and paste the following command and hit Enter to execute it:

dism /online /enable-feature /featurename:MediaPlayback

• Close Command Prompt and then open the app once again to check if the problem is now fixed.

Option 3 – Try extracting a copy of the mfplat.dll file from the windows.old directory

If you encounter the error shortly after you just upgraded to Windows 10 from an older version, the best thing you can do to resolve the problem is to use windows.old directory to fetch an old copy of the mfplat.dll file. To do so, follow the steps below.

• Go to the Windows drive and then look for the windows.old directory where it preserves a copy of your old operating system as well as associated files in case something goes out of hand during the upgrade process.
• After that, open the windows.old folder and then go to the syswow64 folder.
• Next, from the syswow64 folder, copy the mfplat.dll file and paste it to C: windows syswow64.
• Restart your computer and check if the error is now resolved or not.

If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 4 – Update the Device drivers

Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
• Then go to the Startup tab and select Microsoft OneDrive and then click Disable.

Error Code 0xC004C020 (Code 0xC004C020) – What is it?

Error code 0xC004C020 (Code 0xC004C020) is an error that occurs when you attempt to activate a copy of Windows 7 with a key, but the key has already been activated multiple times. When receiving this error code, it means that you are trying to exceed the number of times that the Windows 7 key is allowed to be activated. Common symptoms include:

• Attempting to install Windows 7 with a key and a dialog box with the code 0xC004C020 is displayed.
• The computer is unable to install Windows 7 with the key.
• Certain features will refrain from working until the correct key has been entered.

Solution

Error Causes

Error Code 0xC004C020 occurs when you are not able to install Windows 7 using a previously purchased key code that has been installed numerous times previously on the same computer.

• You are not able to use your previously used key to install Windows 7.
• You have used the Windows 7 key the maximum number of times allowed.

Error code 0xC004C020 simply means that the Windows 7 code that you are trying to use to install Windows 7 has already been used the maximum number of times allowed, even when installing it on the same computer that it was previously used on. This would indicate that the key is what is known as a volume key- meaning that there is a cap on the number of uses.

Further Information and Manual Repair

Many people encounter this problem when they are doing software development or testing and need to reinstall Windows 7. Some people might also encounter this error code when installing Windows 7 with a key that was used too many times previously. It should be noted that there are several ways to fix this problem, but if nothing is working, you should contact a computer repair technician.

Method One

Activate by phone- the long method.

1. Click the start button, right-click Computer, click Properties, and then click Activate Windows.  This will open Windows Activation.
2. Click on “Show me other ways to activate”.
3. Find and enter the Windows 7 key, then click Next.
4. Click on “Use the automated phone system”. If you are prompted for an administrator password or a confirmation, confirm or type the password now.
5. Select the location nearest to you and then click the Next button.
6. There will be a list of available phone numbers, choose one and call it. There will be an automated system that will guide the activation process.
7. Enter the installation ID when prompted, it will be listed on your computer screen.

Method Three

Error code 0xC004C020 occurs if you have used your Windows 7 activation key on multiple computers, or multiple times on the same computer. You are not allowed to exceed the uses of the key—you should consider purchasing a new key if this is the case. A Windows 7 key is available for purchase online through the Microsoft website, in the shop section. The new product key must then be activated within 30 days, or it becomes no longer valid. It can be activated online or through the telephone. If it is not activated on time, features will stop working until the new key has been activated. This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary. If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Windows users need to be on high alert. Microsoft has confirmed a critical vulnerability has been found in all versions of Windows which presents an immediate threat, and you need to act now. A critical new zero-day hack has been found which affects all Windows versions. Tracked as CVE-2021-34484, the “zero-day” flaw enables hackers to breach all versions of Windows (including Windows 10, Windows 11, and Windows Server 2022) and take control of your computer. Microsoft mistakenly thought it had patched the vulnerability (which was first found in August) when it was publicly disclosed in October. But the fix itself was found to be flawed, something the company admitted, and this drew even more attention to the vulnerability. Microsoft subsequently promised to “take appropriate action to keep customers protected” but two weeks later, a new fix has still not arrived. Luckily the third-party security specialist 0patch has beaten Microsoft to the punch with a ‘micropatch that it has now made available for all Windows users “Micropatches for this vulnerability will be free until Microsoft has issued an official fix," 0patch confirmed. You will need to register for a 0patch account and install its download agent before the fix can be applied, but with 0patch fast becoming a go-to destination for hot fixes which beat software companies to the punch this is a no brainer. Hopes will be high that Microsoft can release an effective patch sooner rather than later but, until then, all Windows users must act now if they want to be safe.

There are times when an IT admin has to set up multiple IP addresses to the same network adapter. Setting up multiple IP addresses in scenarios like hosting various SSL sites, speed up traffic exchanges can help in avoiding being blacklisted in the SPAM filters, and so on. So in this post, you will be guided on how exactly you can assign multiple IP addresses to the network adapter in your Windows 10 computer. There are several ways to assign multiple IP addresses in a network adapter. You can do it using the Network Adapter settings or using the Netsh utility, as well as the Windows PowerShell utility. To get started, refer to each one of the options provided below.

Option 1 – Assign multiple IP addresses via Network Adapter settings

• Go to Settings first and from there, select Network & Internet, and then click on the Change adapter options. This will show you a list of both the physical and virtual network adapters in your computer.
• Next, double click on the Ethernet adapter where you want to assign the multiple IP addresses and then click on the Properties button.
• After that, you should see the Ethernet properties where you have to select the “TCP/IPv4” or “TCP/IPv6”.
• Once done, click on the Properties button and then select the “Use the following IP address” option under the General tab.
• Now you have to add an IP address, subnet, and default gateway to the network adapter and then click on the Advanced button.
• This will open the Advanced TCP/IP settings where you have to click on the Add button so you can add an IP address. From here, you can keep adding multiple IP addresses to the network adapter. You also have the option to add multiple gateways or DNS IP addresses.
• Once done, if you execute the “ipconfig” command, you should see all the secondary IP addresses listed.

Option 2 – Assign multiple IP addresses using the Netsh command

Another way to assign multiple IP addresses to your network adapter is via the Netsh command.

• In the Start Search, type “command prompt” and from the search results that appear, right-click on Command Prompt and then select the “Run as administrator” to open it with admin privileges.
• If a User Account Control or UAC prompt pops up, just click on Yes.
• After that, run this command: Netsh int ipv4 add address name="Local Area Connection" 192.168.100.100 255.255.255.0 SkipAsSource=True

Note: You have the option to set “SkepAsSource” since it depends on your needs using the Netsh command. When it is configured as true, the IP address won’t be used by the OS for outbound connections.

Option 3 – Assign multiple IP addresses via Windows PowerShell

• Tap the Win + X key combination and click on the “Windows PowerShell (Admin)” option.
• After opening Windows PowerShell as admin, use the NetIPAddress command so you can add more IP addresses. Execute this command: Get-NetIPAddress | ft IPAddress, InterfaceAlias, SkipAsSource
• Next, assign an IP address to a network adapter by executing this command: New-NetIPAddress –IPAddress 192.168.100.100 –PrefixLength 24 –InterfaceAlias “vEthernet” –SkipAsSource $True
• Now to modify the “SkipAsSource” parameter, use this command: Get-NetIPAddress 192.168.100.100 | Set-NetIPAddress -SkipAsSource $False

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.

As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.
• Navigate to the option “Control the mouse with keyboard” and then uncheck the “Turn On Mouse Keys” option to turn off the Mouse key.
• Click on Apply and then on OK to save the changes made.

Note: The problem with the keyboard could stem down to a simple issue in its settings so if you have successfully followed the steps for this solution then you should be able to fix the problem.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Keyboard from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.
