Windows is stuck on signing out screen

What Does 0x8007045D Error Code Mean?

The 0x8007045D error code is an I/O (input and output) error that is associated with the registry. It indicates that the Windows operating system has become overloaded with invalid system references in the registry. This may prevent you from executing reading and writing to and from devices successfully.

Error Causes

Registry is the main database of your PC. This portion of your computer saves all the activities that you perform on your PC including the junk files, temporary internet files, invalid entries, bad registry keys, and more. This clutters the hard disk. If the unnecessary files are not removed from the registry, it may lead to I/O errors like 0x8007045D. On the hard drive, some parts of the drive may fail to function. If this is not fixed on the time it may lead to serious disk damage and registry corruption eventually resulting in system failure. System failure can make you lose all the valuable data saved on your system for good.

How to Fix the Error Code 0x8007045D?

Error codes on your PC are like warnings. These codes indicate that your PC has some issue. Therefore ignoring it is not wise. To spare yourself from such serious PC damages, it is advisable to take correct measures timely instead of prolonging and making the situation go from bad to worse.

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.

There are cases when you encounter some issues while updating your Windows 10 computer. One of these issues is the error 0x80240034. This particular error is a Windows Update Error that appears on the Windows Update pane every time an update fails to install. When this happens, your Windows Update will only get stuck at 1% and nothing happens afterward and eventually fails. If you click on the View Installed Update History, you will see the error code 0x80240034 for the failed updates. You will see this error each time you try to update your Windows PC. Take note that this issue doesn’t only happen to a specific version of the Windows Update but on various different Windows builds based on many users. What’s more, is that some users are also seeing a different error code when their Windows Update fails but they still end up seeing the error code 0x80240034 when they check the Windows Update history. At the time of writing, it isn’t determined yet what really causes this error but it’s most likely due to some corrupted files in the computer which is why the most common solution you can try is resetting the Windows Update cache. On the other hand, other users also resolved the issue by using the ISO and selecting the “Do not keep previous settings” option during the Windows Update so it might be something to do with transferring the previous settings through the update client. For clear instructions in fixing this issue, refer to the two options provided below.

Option 1 – Try to clear the Windows Update Cache/Distribution Folder

As mentioned earlier, a lot of users tried clearing the Windows Update cache to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Step 1: Tap the Windows key once.
• Step 2: Next, type in “command prompt” in the Windows Start Search, and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Step 3: After opening Command Prompt, type in “net start wuauserv” and hit Enter.
• Step 4: Then type in “rmdir %windir%SoftwareDistribution /S /Q” and hit Enter.
• Step 5: Now type in “net start wuauserv” and hit Enter. Once it’s done, try updating your Windows PC again, it should now work just fine.

Option 2 – Update Windows via ISO file

If option 1 didn’t work for you, you can try this second option of updating your Windows 10 computer using an ISO file which means that you will have to create a Windows 10 bootable media and use it to install the latest Windows 10 version. The most user reported that this option works and the reason why it does have something to do with the Windows Update client since the Windows Updates downloaded from the regular Windows Update client seems to create issues such as the error 0x80240034. However, issues like this one don’t occur when the very same Windows Updates are downloaded and installed via an ISO file. Take note that when using a Windows ISO file, you will be asked to choose what you want to do with the previous settings and apps. A lot of users opted for the “Not to keep the old Windows settings” option which has resolved the issue. So if you want to keep the previous settings then you must try to update Windows first while keeping the old settings. However, if it doesn’t work, you have to try installing the latest version of Windows without keeping the previous settings.

• Step 1: Click this link and then click the Download Tool Now button.
• Step 2: Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Step 3: Now select the ISO file option in step 5.
• Step 4: After that, you should now have an ISO file.
• Step 5: Next, go to the location where you’ve downloaded the ISO file.
• Step 6: Then right-click on the Windows 10 ISO file and select the Open with an option and then select File Explorer.
• Step 7: Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either: Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

One of the hardest issues you can encounter on your Windows computer is the Blue Screen of Death error. There are various kinds of BSOD or Stop errors and one of them is the “Memory Management Error 0x0000001A” error. This kind of Stop error might signify a hardware problem in your computer and is most likely caused by an issue with RAM or hard disk or even malware that takes up all your computer’s memory, thus, making it crash and display a BSOD error like the Memory Management Error 0x0000001A. Moreover, this kind of Stop error can also occur during the Windows upgrading process. So in this post, we’ll show you what you can do to fix the Memory Management error on your Windows 10 PC.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Update the device drivers

• Tap the Win + R keys to launch Run.
• Type in devmgmt.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. Look for the device driver you and then select either “Update driver” or “Uninstall device”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
• Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 3 – Run the Windows Memory Diagnostics Tool to test RAM

Since the issue concerns the memory of your computer, you can also try running the Windows Memory Diagnostics Tool to find out if the RAM module of your computer has become corrupted. To run this tool, follow these steps:

• Tap the Win + S keys to open Search.
• Then type “Windows Memory Diagnostics Tool” in the field and hit Enter to open the Windows Memory Diagnostics Tool.
• After that select any of the following option from the prompt that appears:
  • “Restart now and check for problems (recommended)”
  • “Check for problems the next time I start my computer”
• After that, if you find that your RAM is corrupted, you might have to purchase a new one or change the motherboard of your computer.

Option 4 – Run the DISM tool

There are cases when the Memory Management Error 0x0000001A error is caused by the Windows System Image so you need to repair it using the DISM or Deployment Imaging and Servicing Management tool. The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: Dism /Online /CheckHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the SFC scan

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

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 6 – Try using System Restore

You can also try to perform a System Restore as it can also help you fix the BSOD error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
