Error Code 0x8007041d - What is It?

Error Code 0x8007041d is an error that arises during the Windows 10 Update process. In some cases, this error code can also arise during the Windows 10 Activation process. It is an error code that has been present in multiple versions of the software but usually arises when antivirus or registry issues interfere with the Windows Update or Activation software.

Common symptoms include:

• Inability to download the needed Windows 10 updates
• Inability to complete the Windows 10 Update process

If you are experiencing the Error Code 0x8007041d on your machine, there are several methods that you can use to attempt to resolve the problem. Several of the steps that are most successful for the resolution of this error require familiarity with registry and antivirus tools, so if you are unsure of your ability to complete these steps on your own, contact a qualified computer repair technician to assist you.

Solution

Error Causes

In most cases, Error Code 0x8007041d arises when there is a conflict between multiple antivirus or malware tools on the computer, if there is an issue in the Windows registry, or if your Windows Defender software is out of date. During the Windows Update process, the system checks to ensure that there are not any factors that are present that could introduce viruses to the system, so if there are any indicators that could present issues to the software, Error Code 0x8007041d will often arise.

Further Information and Manual Repair

For users who experience Error Code 0x8007041d, there are several steps that can be taken to resolve the issue. If the following methods are not successful for you or if you are unsure of your ability to undertake them on your own, contact a qualified Windows 10 computer technician.

Here are the best ways to attempt to fix Error Code 0x8007041d on your computer:

Method 1:  Remove Additional Security Software Apart from Windows Defender

In some cases, having multiple versions of malware or antivirus software installed on your computer can cause the Windows system to create conflicts between them, which can interfere with your ability to update. During the update process, the system may attempt to determine if there is any malware present, and having multiple kinds of antivirus software present on the same machine may return mixed results.

If you currently are running antivirus software that is separate from Windows Defender, consider removing it from your computer prior to running the update software. This may allow you to successfully complete your update process without conflict. Additional software can be reinstalled after the update is complete, but make sure to keep both sets of software up to date in order to lessen the chances of encountering this error code again during future updates.

Method 2:  Update Your Windows Defender Software

If you currently have Windows Defender as your primary antivirus software, check to see whether it is fully up to date. Out of date antivirus software can cause conflicts with the Windows Update process since the update to Windows 10 will not be able to be completed unless the system is free from viruses or malware.

If you are unsure of whether or not your Windows Defender is up to date, open it and run the process to check for updates, then re-attempt to run Windows Update. In some cases, you may want to restart your computer before running the Windows 10 Update process a second time.

Method 3:  Run the Registry Repair Tool

Another issue that could cause Error Code 0x8007041d is a problem in the system registry. If you believe that this may be the case, run the Windows Registry Repair Tool on your machine to check for and resolve any issues. This is a fairly simple and straightforward tool to use, but it can help you to resolve any number of problems that may interfere with your ability to update your Windows 10 software.

If you have taken the steps listed above, restart your computer before attempting to proceed with the Windows Update process. If the three methods listed above are not successful in completely resolving Error Code 0x8007041d on your machine or if you are not comfortable in your ability to implement these steps on your own, contact a qualified Windows repair technician who is familiar with the Windows Update process to assist you.

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.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

There are times when it is really inevitable to delete your hard drive partitions especially if you are already running low on disk space in your Windows 10 computer. Users typically delete the volume which is not being used in such cases in order to free up some space for the volume that’s running low on disk space. To resolve the problem, users tend to use the Disk Management utility to delete hard drive partitions. However, some users reported that the “Delete volume” option is not available as it is grayed out. Thus, users aren’t able to delete hard drive partitions and aren’t able to free up disk space. This kind of problem usually occurs when there is a Page file on the volume that you are trying to delete and so on. Oftentimes, this issue is mistaken for the problem where you are unable to delete an EFI-protected partition. However, in this case, not only you are unable to delete EFI-protected partition but also NTFS file systems. This is really hard to deal with but worries not for there are some potential fixes you can check out to resolve this problem.

Option 1 – Try to manage the Page file in the Partition

As mentioned earlier, if a Page file exists in a partition, you won’t be able to delete it. The page file is what stores your data when the system’s random access memory fills up. To resolve this, follow these steps:

• After entering this command, the Diskpart Utility will start. Diskpart Utility is a command-line-based utility just like Command Prompt but it will get a UAC Prompt after you invoke it so you have to click Yes for the UAC Prompt.
• After that, type in list volume and tap Enter to see the list of all the partitions created on your PC. This includes both types of partitions that are visible to the normal users in the File Explorer as well as the ones that are created by Windows 10 by default which helps it in storing the boot files and other essential system files.
• You should see a list of all the partitions made on your computer. Select the partition you want to delete by its Unique Identification number as Volume X where X denotes the Unique Identification Number.
• Next, type in the select volume number command and hit Enter to select the desired volume.
• Then delete the volume you’ve selected and type in the delete volume command and hit Enter to delete the volume you just selected and convert it into unallocated space.

Option 3 – Delete storage partition via Windows PowerShell

• Start by tapping the Win + X keys or simply right click on the Start button and select Windows PowerShell (Admin) or you could also type in “Windows PowerShell” in the Cortana search box and right-click on the Windows PowerShell icon and select the “Run as administrator” option.
