Solution

Error Causes

Error code 0x80070652 may result from Windows 10 users attempting to download another program while upgrading their operating system. It may also be caused by an issue related to previous installations of updates. For instance, in some cases, your previous installation of the Windows process may have been interrupted or it was simply not completed properly. This causes any other upgrade process that follows to result in error code 0x80070652.

Further Information and Manual Repair

But what can be done in such a situation to resolve the error code? Windows users have several options available. For instance, they can wait on any additional program that may be in the process of downloading to complete the process before attempting to upgrade Windows. They may also troubleshoot problems related to any failed updates or select a system restore point in which the error code was not present.

The manual repair methods Windows 10 users choose may involve any of the solutions mentioned previously. The choice is largely dependent on the user and his determination to fix the error code. However, note that automated tools or Windows repair technicians may also provide solutions to PC issues like error code 0x80070652.

Method One: Verify and Troubleshoot Failed Upgrades

Since previously failed updates within Windows Update can lead to the occurrence of error code 0x80070652, Windows 10 users will need to verify which of these failed updates occurred by checking the history section of the Windows Update tool. Once you’ve been able to verify that failed updates have occurred in the recent past, you’ll need to troubleshoot these problems to rectify the error code. Follow the instructions below to check for updates that have failed to install properly via Windows Update.

• Step one: Type Windows Update in the Search box near Start Menu
• Step two: Select Windows Update settings
• Step three: Select Update history
• Step four: Review updates from the most recent to least recent to see which updates have failed
• Step five: Click failed updates for more details and troubleshoot accordingly.

Once you’ve completed the troubleshooting of any updates which failed, proceed by rebooting your device. You may then reattempt to upgrade to the latest version of Windows 10 once no other program is in the process of being downloaded.

If the problem causing error code 0x80070652 was related to failed updates of the past, these issues will likely be resolved once you successfully troubleshoot them. However, if the error code reoccurs, apply the next manual repair solution mentioned in this article.

Method Two: Download Updates Manually via Microsoft Download Center

Another option available to users is simply downloading updates manually by visiting the official Microsoft website, specifically the Windows section which provides downloads. To successfully complete this process, ensure you look for stand-alone packages of these downloads available on the website. You will need to know the Microsoft Knowledge Base (KB) article number related to the specific update(s) which failed.

Once a Windows user has verified the KB article number of the specific update, download it from the Microsoft website, then select Run to install the update. Reboot your PC, then check Windows Update to see if you are able to successfully complete the Windows 10 upgrade.

If the upgrade fails, you may need to implement the next manual repair method as is mentioned below.

Method Three: Use Windows System Restore

One of the best options for Windows 10 users facing certain PC problems is to apply System Restore. This allows them to reset their machine for a period of time in which the problem was not present. This is known as the restore point. To apply this manual repair method, follow the steps below.

• Step one: In the search box beside the Start Menu, type System Restore
• Step two: Select Create a restore point
• Step three: Select the System Protection tab then Configure or Create
• Step four: Provide details regarding a system restore point of your choice

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.

If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /[DLL file]
  • exe [DLL file]

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

• First, you need to get the new DLL file from another computer with preferably the same file version number.
• After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
  • x86: This PC > C:/Windows/System32
  • x64: This PC > C:/Windows/SysWOW64
• Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
• Now type the “regsvr32 ntdll.dll” command and hit Enter.
• Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

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

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.

Option 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.
