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.

If you recently upgraded your computer or if you’ve just switched to a new Windows 10 PC, the most common errors you might encounter are the Windows Activation errors. This issue boils down to the Windows Activation server which has either failed to validate or recognize the license tied to the digital account. In this post, you will be guided on how to fix an activation error in an organization with an error code 0x8007007B. It contains this exact error message: “We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.” Various computers are activated via the KMS licensing (Key Management Server) in organizations. Computers that are activated using this process do not get a permanent activation and have to stay connected to the organization instead of for at least 7 months or 180 days. It is common in Pro and Enterprise versions that are deployed in bulk for at least hundreds or thousands of computers. So imagine a user with a personal computer in the office who decided to leave the organization but will still have an activated Windows key. And so to prevent that from happening, organizations use the KMS licensing. Another possible cause of the error is in case some user used an organization key and later on, the PC just got upgraded or downgraded to a version that is not compatible with that copy of Windows. To fix this Windows Activation error, here are some suggestions that might help.

Option 1 – You can try connecting to the organization’s network and activate the computer. But before that, you need to first check if the computer actually belongs to an organization or not.

• Tap the Win + R keys to open the Run dialog box.
• Type “cmd” and hit Enter to open an elevated Command Prompt.
• After that type the vbs /dlv command and hit Enter to execute it.
• Next, check if the Product Key Channel says “GVLK”. If it does, then it means that your computer was activated using volume licensing.

Option 2 – Change Licence Key

If you’ve recently left an organization then it’s best if you buy another copy of Windows 10 and then change the license key. This time, make sure that the license key is for the same version of Windows. However, if it’s different, you need to format your computer.

Option 3 – You can try activating Windows 10 using a 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 4 – If you think that the issue is caused by some hardware changes, you can try using the Activation Troubleshooter.

There are times when users already have the license keys and were able to activate Windows. However, it doesn’t last long and only works for a while and it’s suddenly throwing up an activation error like this one. To use the Windows Activation Troubleshooter, just go to Settings and to Activation and then run the troubleshooter from there. If you've made some modifications to your hardware, you have to click the “I changed hardware on this device recently” option for further suggestions.

In the last article, we have covered various advantages of Apple hardware over Windows PC, however, PC has their own strengths and advantages over MACs as well. Join us as we explore why would you choose Windows PC over MAC.

Hardware customization

If you like to customize and build your own hardware and customize your existing computer then MACs are out of the picture, on other hand, computers based on Windows operating system are much more flexible in terms of customization.

While Apple hardware is locked and only allows small changes to it, computers running on Windows are free and open to various upgrades and modifications so if you like to play with hardware Windows is your platform.

Gaming

There are games on MAC true but their numbers can not compare to games available for the Windows platform. On top of that, most latest and best gaming hardware is not even available on Apple platforms so if you plan to game in high resolutions and play the latest games there really is no option other than Windows.

Windows Platforms also has multiple emulators that you can use to play games from other older platforms and Microsoft since it owns Xbox has some great plans for both PC and Xbox gaming.

Software back compatibility

Since the introduction of the new MAC OS X, apple really lost a lot of application back compatibility, and a lot of old legacy software can not be run on modern Apple computers. Windows on the other hand have always tried and succeeded in keeping maximum compatibility with older and legacy software.

Also on the Windows platform, there is a lot of community support for old and legacy software so even if it is not officially supported it is backed up by the community.

Software variability

In terms of where can you find the most different software, you need to look no further than the Windows platform. How Windows itself has great backward compatibility and a lot of developers are using it to create new software thanks to Visual Studio and .NET Windows has cemented itself as a platform with the most available software.

The popularity of Windows as the home operating system and as a gaming platform has made it quite interesting in eyes of various developers and tons of small applications are made daily for it. Windows 11 has also brought native android support to it and that has just expanded its already impressive catalog of applications.

Freedom of choice

Overall Windows PC is most appealing for users that like to be able to choose everything, from hardware components to software they would like to use. No other platform will give you larger freedom of choice and better personalization options.
