How to Fix ntdll.dll crash Error on Windows

If you got an Activation Error 0xC004F211 after having installed or upgraded your Windows 10 PC, then this indicates that some hardware in your computer has changed which’s causing the error to pop up. Windows might not be able to determine if the key is used on a new computer or if it’s still the same one if you have just removed or upgraded old hardware. But worry not for this post will guide you in fixing the Windows Activation Error 0xC004F211 on your Windows 10 computer. When you encounter this error, you will see the following error message on your screen:

“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”

Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error. In such cases, the Windows Activation system will treat this as new hardware and you will need a new license for that. Even if your Windows 10 computer has a genuine key, it might still fail to get activated which results in the Windows Activation Error 0xC004F211. Thus, before you do other troubleshooting steps, you need to run the Windows 10 Activation Troubleshooter first. To do so, follow these steps:

• 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.

In addition, there is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

The speed at which the CPU runs varies depending on any Windows laptop or desktop. And in case you don’t know, the CPU does not run at full speed all the time as it depends on how the operating system distributes the load so it works accordingly. However, there are instances when it runs at full speed especially if your Windows 10 computer is on a heavy workload. But if you find that even when your computer is already on a heavy workload and the CPU is still not running at full speed, then you need to look into this situation. To verify that your CPU’s speed, you can use any CPU stress test tool. This kind of issue is common on laptops compared to desktop computers since laptop runs on battery. The Intel Processor on laptops uses the Speed Stepping Technology which means that when you are doing some small tasks on your laptop, the processor’s speed is reduced. On the other hand, if this happens when you are using a heavy application, it can be due to a low charge on the laptop’s battery. Thus, Windows will try its best to keep the computer running for as long as possible by reducing the CPU speed or processor. But there are times when you are ready to sacrifice battery to make sure that the work gets done on time. To achieve that, here are some options you can check out.

Option 1 – Try setting the processor state to the maximum in Power Options

• Type “control” in the search box to view the classic Control Panel as well as the popular options.
• Next, click on Power Options > Change plan settings > Change advanced power settings.
• Then navigate to Processor power management > Maximum processor state.
• Now select 100% when it is on Battery and Plugged in.
• After that, expand the System cooling policy option and make sure to set it as Active to make sure that the battery won’t overheat.
• Finally, apply the changes made to all the profiles of the power management and restart your computer. This will ensure that your CPU will run at maximum power at all times.

Option 2 – Try to update or disable the Intel Power Management driver

The next option you can try is to update or disable the Intel Power Management driver. The Intel-powered computers have dedicated software that controls CPU speed and Fan speed when it needs to save battery. You can try disabling it temporarily and check if there are any changes with the CPU fan speed.

• First, restart your computer by holding the Shift key to boot your computer into Troubleshooting or Advanced mode.
• Next, go to Troubleshoot > Advanced Options > Command Prompt.
• Then change the directory to C:/Windows/System32/driver and then rename the file named “Intelppm” by entering the “ren intelppm.sys intelppm.sys.bak”.
• Now restart your computer.

Note: If you were not able to find the drivers in C:/Windows/System32/driver, check if they are available under C:/Drivers/IntelPPM. After that, the CPU speed should change now with the Intel driver missing from the system. And in case you want to enable it, simply follow the same steps given above and rename the file again.

Option 3 – Try disabling the IPPM using the Command Line or Registry Editor

• Command Prompt:
  • Tap the Win + R keys to open the Run dialog box and type “cmd” and tap Enter to open Command Prompt.
  • Next, type this command and hit Enter: sc config intelppm start= disabled
  • The “sc config” command you entered modifies the value of a service’s entries in the registry as well as in the Service Control Manager database.
• Registry Editor:
  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesintelppm.
  • From there, double click on the intelppm and change the Start key value to
  • Now close the Registry Editor and reboot your computer.

Note: The steps given will make sure that the CPU will run at maximum power at all times.

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

Option 1 – Try to disconnect or disable newly installed hardware

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

Option 2 – Try to update the BIOS

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

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

Option 3 – Try to reconfigure all the created partitions

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

Option 4 – Make a proper bootable USB Drive/Stick

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

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

If you continuously encountered the “VirtualBox FATAL: No bootable medium found, System halted” error when you try to install Windows 10 in VirtualBox, read on as this post will give you some potential fixes to resolve the problem – you will be guided on how to choose the ISO image to fix this error in VirtualBox. This kind of error is a very common one especially if you have a corrupted ISO file or if you have not selected an ISO file for your virtual machine. Like pointed out, this error pops up when you have a corrupted ISO file or if the ISO file is not attached to the virtual machine. You have to select the ISO file while you create the virtual hard disk, else, you will most likely face this problem, and to fix it, you need to download fresh Windows ISO, create a new IDE Controller, assign Windows ISO to the IDE Controller and then boot your virtual machine. For detailed steps, follow the instructions below but before you start, make sure that you have a valid and uncorrupted Windows ISO. Step 1: First, you need to open the VirtualBox program on your computer and select the virtual machine. Step 2: Next, click on the Settings button or you can also right-click on the virtual machine and select Settings from the context menu. Step 3: Once you’re in the Settings panel, go to the Storage section and from there, create a Controller: IDE. Step 4: To create a Controller: IDE, click the Add new storage controller icon and select the “Add IDE Controller” option. Step 5: After that, click the Add optical drive icon and click on the Choose disk button. You will then see all the attached and non-attached ISO files. However, you have to add the new ISO file that you just downloaded. Step 6: To add the new ISO file, click the Add button and select the ISO file and then select the .iso file from the Non Attached section. Step 7: Now click the Choose button and afterward, make a checkmark in the Live CD/DVD checkbox and then select the IDE Primary Master from the drop-down menu of the Optical Drive. Step 8: Once you’re done, save the changes made and try booting into your virtual machine again.

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.
