Error 0xc0000225 is the error that occurs on system startup, most times error just disappears all by itself but in some cases, it can be really persistent and can even cause you not to be able to enter the system that could be a really annoying thing, especially if there is some important task waiting to be finished. In this guide, we will present you with solutions for this error and how to solve it so you can get back to work as soon as possible.

Solution if you can not log into windows due to repeating error

If an error repeats itself constantly and you are unable to boot into Windows itself you will need to prepare Windows boot USB. You can download the Microsoft media creation tool here and then use it to create a bootable USB with Windows 10. Once the USB is done reboot your system and boot from USB. CHoose repair Windows instead of install and follow onscreen instructions.

Solution if you can log into Windows

If you can log into Windows bring up the command prompt in administrator mode and type in it SFC /SCANNOW followed by ENTER, wait for the whole operation to finish, and then reboot the system.

nslookup is a command-line tool that helps in finding the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. Aside from that, it can also perform some complex functionality such as finding details about FTP server, Mail server and many more but most of them are used by administrators. The best thing about nslookup is that it queries the DNS server directly and it does not rely on the cache. On the other hand, there is another tool called PING that is used to verify connectivity. PING sends a packet of information to the IP address or Domain and gets back a response in the form of packets. So if everything goes well, all packets are received but if not, it will help you find out where the delay in the network exactly is. However, the ping command does not always attempt a DNS lookup which means that it might be using the DNS cache and use the IP address available in that table. Although both nslookup and PING help you in identifying the host or IP address, however, they don’t always work and sometimes fail. So if your nslookup works but ping fails on your Windows 10 PC when querying the IP address of a website then it could be caused by many reasons. It could be that the nslookup queries work for you but when you try to use PING, it fails. For instance, if you open the abc.com website, here’s how it will look like:

nslookup xyz.com Server: dns.company.com Address: 192.168.1.38 C:> ping xyz.com Ping request could not find host xyz.com. Please check the name and try again.

The domain is converted into an IP address and then data is sent to that IP address when you use PING. So when a reply comes back it means that the data is going back and forth to that domain without any problem. However, if the DNS fails to resolve the IP address of the website or if your PC does not attempt a DNS lookup, you will receive a similar error message that says, “Could not find host” and so on. To resolve this issue, here are some options that might help.

Option 1 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the issue with nslookup and PING. 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 2 – Force Windows to do a DNS lookup using FQDN

• Go to Settings > Network & Internet > Status > Change adapter options.
• From there, right-click on the network and select Properties.
• Next, in case you’re using IPv6, from the list of connections available in the list, select Internet Protocol Version 4.
• Then click on Properties and click Advanced.
• After that, switch to the DNS tab and select “Append these DNS suffixes (in order)” and click on the Add button and then add “.” as a suffix so that each time you query using PING and another tool, it will add a “.” at the end and will force the lookup.

Option 3 – Make sure that there is only one default gateway

If your computer has more than one NIC connected and there are multiple default gateways, then it will most likely create confusion which is why you need to remove the default gateway from the configuration of all NICs and make sure that there is only one default gateway.

Option 4 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the nslookup and PING issues. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Check the Windows Host file

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why PING fails even when nslookup works. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 6 – Delete the WLAN Profiles

Deleting the WLAN Profiles might be a good idea if you are not able to connect to the internet on your computer and if you’re using Wi-Fi. It could be that the networks that were connected previously have gone rogue which is why it is not connecting properly. And so deleting the WLAN profiles might help you in fixing the issue with nslookup and PING.

Option 7 – Reinstall the Network Adapter Drivers

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and select “Uninstall device”.
• Restart your PC.

Error Code 0x80070004 on Windows 10 – What Is It?

Some users trying to upgrade from Windows 7 or Windows 8/8.1 reported experiencing installation rollback with error code 0x80070004. This error normally appears when the Computer Name is set to names that can’t be used for the computer. It’s also possible this error occurs if users or program files folder were redirected to a different partition.

Solution

Error Causes

The Error code 0x80070004 on Windows 10 is normally caused if any of the following were used as the Computer Name and the user tried to upgrade to Windows 10:

• System (or SYSTEM)
• SELF
• LOCAL
• Network

Failure to fix this error message might result in others, including error code  0xc0000001. 

Further Information and Manual Repair

If you don’t solve this error, you won’t be able to upgrade from Windows 7 or Windows 8/8.1 to Windows 10. Note that this error will continuously bring you back to the original OS unless fixed.

Please note that if you’re not confident in doing these steps, you might want to consider seeking the help of an expert or using an automated tool that will help fix this.

Here are a few methods to try.

Method 1: Check and Change the Computer Name

The most common cause of this error is if your computer uses any of the following reserved names:

• LOCAL
• System (or SYSTEM)
• Network
• SELF

These reserved names are not meant to be used as computer names. If this is what your computer uses and you try to upgrade to Windows 10, you will surely get this error. Check your computer name and if you see any of the reserved names, change it right away.

Changing Computer Name in Windows 8.1

If you’re trying to upgrade from Windows 8.1, you can change the name of the computer by following these steps:

• Step 1: Open the Start menu then simply type “rename computer”. After that, choose “Rename this computer”
• Step 2: A dialog box will open. Just click the “Change” button
• Step 3: A new dialog box will open. Type the new name. Click Apply then Ok.

Changing Computer Name in Windows 7

If you’re trying to upgrade from Windows, you can follow the steps below to change the name of your computer.

• Step 1: Go to the Start menu then on the Computer section, right-click the mouse and choose “Properties”.
• Step 2: A new dialog box will appear. Go to “Computer name, domain, and workgroup settings” then click “Change settings”. In case you’re asked for administrative access, make sure to grant it.
• Step 3: Find the “Computer Name” tab then click “Change”
• Step 4: Change the computer name and click Ok.

Method 2: Fix the “Users” directory issue

If the first method doesn't work, it probably means the computer name isn’t the cause of this error. Another reason why users experience Error code 0x80070004 when upgrading to Windows 10 is if the “Users” directory was relocated. So, when you try upgrading to Windows 10, the installer wasn’t able to find the user profiles on the “%systemdrive%”, where the current operating system is installed.

If you changed or moved any of the Users, Program Data, or Program Files folders, this will cause the error. Before you upgrade to Windows 10, you might be required to reset or reinstall your current operating system (Windows 7 or Windows 8.1).

If you haven’t made any changes or haven’t moved any of the mentioned folders, there’s a great chance that your users' profiles are corrupted. You can also reinstall your current operating system. However, you might want to check for the corrupter user profile first. To do this, follow the steps below:

• Step 1: Go to the Start menu and type System
• Step 2: Click System  then go to the Advanced tab
• Step 3: Go to Settings, which you’ll find under User Profiles

On the Users Profiles, make a copy of all the accounts somewhere. Sign out from the current user account then try logging in back using the accounts you’ve copied. For each account, you get an error, delete it. However, make sure that you don’t delete the UpdateUser and Administrator account ever.

After this is done, try upgrading your operating system to windows 10 again.

Method 3: Try a trusted and secured Automated Tool

If the above methods still not useful, you might want to rely on an automated tool. Find a secured and trusted tool. It will help fix this issue.

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.

Error Code 0x8024001b- What is it?

At its most basic level, Error Code 0x8024001b is an error that can cause problems with the installation and updates of software and operating system updates. The most common version of this error appears in Windows 10, but a similar error with a matching code number has been present in previous versions of the operating system, back through Windows 7.

Common symptoms include:

• Programs freezing or locking up during use
• The appearance of an error message regarding installation difficulties
• Computer shutting down or freezing during operation
• Difficulty in running multiple programs at the same time

Solution

Error Causes

There are two main causes for Error Code 0x8024001b, both of which are fairly simple:  Updates needed for the Windows Update tool itself and software that causes Windows Update to fail during installations through conflicts in system files. While these may seem like technical issues, these problems are actually easily resolved with a few simple steps. The average user can use the methods listed below to fix the problems on their own.

Further Information and Manual Repair

For users who want to address Error Code 0x8024001b for themselves, the steps below can be followed to address the two primary causes for the error. If you have difficulty in completing these steps or are not confident in your computing skills and ability to follow the listed steps, contact a Windows repair technician.

Here are the top methods to resolve Error Code 0x8024001b on your own:

Method One:  Check for Updates to Windows Update

In some cases, the Windows Update tool may need an update for itself. When you attempt to run updates or install wizards for other software, it can cause conflicts with the Windows Update process, slowing down your computer or causing it to freeze.

If you are attempting to run multiple installations or updates at the same time, it may also cause Error Code 0x8024001b to arise on your computer.

To resolve this issue, close out all programs, with the exception of the Windows Update tool. Within the tool, select “Check for Updates” and install any updates that are needed. When finished, you should restart your computer to ensure that all updates have been fully applied before attempting any other installations or updates.

Method Two:  Uninstall Conflicting Software

Another problem that can cause Error Code 0x8024001b is the presence of conflicting software. If Error Code 0x8024001b has only recently appeared on your computer, consider removing any software that has been added to your computer, running the Windows Update process, and restarting your computer before attempting to reinstall the problem software.

With any method that you use, it is important to remember to keep your Windows Updates current at all times. This is the best way to avoid the appearance of Error Code 0x8024001b and similar errors in the future, as stacked up updates are more likely to cause issues and conflicts with your other installed software and operating system.

While there are some tools out there that claim to be able to fix Error Code 0x8024001b for you, it is important to always thoroughly investigate the publisher and distributor of such software, as some of the tools available on the Internet will actually introduce malware and adware on your computer in the name of “protecting” your computer or resolving an error.

If you have tried to use both methods above and have not fully resolved Error Code 0x8024001b, get in touch with someone who is a qualified computer repair professional and is familiar with your particular version of the Windows operating system to assist you in finalizing your resolution.

Method Three: Use An Automated Tool

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.

In case you don’t know, Microsoft hooks up every machine that is running Windows 10 with an Advertising ID which helps them in providing Windows 10 users with relevant ads. These ads are delivered to users in the Action Center, Start Menu as well as the ads inside the UWP Applications. What makes these advertisements relevant is that they keep track of your browsing trends, likes and dislikes, with the help of the Advertising ID. However, if you are not fond of advertisements and you do not want this feature of Microsoft to track your usage, worry not for you actually have the option to disable targeted ads on your Windows 10 computer by turning off the Advertising ID. And you can do that during Windows 10 Setup or using the Group Policy Editor. For more details, refer to the instructions provided below for each one of the methods.

Option 1 – Turn off Advertising ID during Windows 10 setup

If you are about to install Windows 10, then during the installation process, your computer boots into the Install and Configure Windows 10 screen with Cortana that assist you during the setup. Once you reach the last page which is “Choose privacy settings for your device”, you will see the Advertising ID of your computer. Under the Advertising ID, you have to disable or toggle off the “Apps can use advertising ID to provide more personalized advertising in accordance with the privacy policy of the app provider” option. After you disable it, click on the Accept button to proceed with the installation. After that, the copy of your Windows 10 you are using will have the Advertising ID disabled by default.

Option 2 – Turn off Advertising ID via Group Policy Editor

• First, tap the Win + R keys to launch the Run utility.

“This policy setting turns off the advertising ID, preventing apps from using the ID for experiences across apps. If you enable this policy setting, the advertising ID is turned off. Apps can’t use the ID for experiences across apps. If you disable or do not configure this policy setting, users can control whether apps can use the advertising ID for experiences across apps.” Note that setting the radio button to Enabled or Not Configured will turn off the data collection of the Advertising ID.

• Finally, exit the Group Policy Editor and then restart your computer to apply the changes made successfully.

The Photos app in Windows 10 is the default photo viewer. However, there are times when it might encounter some problems while you use it. One of these problems in the Photos app reported recently is where users try to export or share the images and videos from the app but weren’t successful in doing so. This can be really quite a hassle in opening images on your computer, especially since the Photos app is the default photo viewer in Windows 10 and if you don’t have any other photo viewer app installed. This kind of problem in the Photos app can be noticed when you try to use the “Remix” function for both photos and videos. In other words, this problem can occur with just pictures, videos, as well as a combination of both. So if you are trying to watch a video using this app, then you wouldn’t be able to play it. In such a case, the only thing you can hear is the audio but you wouldn’t see anything except for a hazy purple screen that has not export or share option. There are several possible causes for this problem and it could be fixed by updating the display driver/graphics driver or disabling the hardware-accelerated video encoding. You could also try updating or resetting or reinstalling the Photos app. For more details, follow each one of the suggestions provided below.

Option 1 – Try to update 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.
• Type in 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. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 2 – Try disabling the hardware-accelerated video encoding

The next thing you can do to fix the problem is to disable the hardware-accelerated video encoding in your computer. To do that, follow these steps:

• Open the Photos app and click on the visible three dots located in the upper right corner of the app and then select Settings.
• From there, you should see the version number of the app in the “About this app” section. So if your app is version 2018.18071.****0.0 or greater, you should see the Video section which has a toggle button.
• Turn that toggle button off to disable hardware-accelerated video encoding in the Photos app. This should fix the problem, if not, simply follow the next given options below.

Option 3 – Try to update the Microsoft Photos app

• Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
• Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 4 – Try resetting the Photos app

• To get started in resetting the Photos app, open the Windows 10 Settings.
• Then go to Apps > Apps & features.
• After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
• From there, you will see the Reset button, click on it and click and then click on it once more to confirm.

Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 5 – Try reinstalling the Photos app

If none of the options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:

• Open the Windows PowerShell program with admin privileges and key in the following command:

Set-ExecutionPolicy Unrestricted

• After that, execute this second command to re-register and reinstall the Microsoft Photos app.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

One of the primary packages that install the Windows Media Player is the Media Feature Pack among other related files that are needed by the associated software products. And one of the essential DLL files in that package is the mfplat.dll file which is needed by various games and streaming services. So if this DLL file goes missing, you will most likely encounter any of the following error messages:

• “mfplat.dll missing”
• “The application failed to start because mfplat.dll was not found.”
• “The program can’t start because mfplat.dll is missing from your computer.”

In other circumstances, the Media Feature Package does not come pre-installed with the main Windows package especially for those who use Windows N, thereby causing the error to pop up. The main cause of this problem is that users who use Windows 10 N do not have the Media Feature pack pre-installed with the installation package. Aside from that, the installation package could go missing after a few Windows Updates or if you have uninstalled it by accident. To resolve this problem, you need to check out each one of the given options below.

Option 1 – Try to 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 2 – Try installing 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 have verified that your PC 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 3 – Try to extract 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.
