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.

Over time Applications change, some for the better some for worse. Some of them even stop receiving updates and are old and vulnerable. Sometimes standards change and some file types are not used anymore. Software evolves along with technology and that is good. Keeping old and useless applications inside your Windows is not so good. From various exploits to simply taking up space, maybe even slowing down OS it is always wise and good to clean your Windows from unwanted old applications. In this article, we will be mentioning some relics of old and providing you with an explanation of why you should remove them from your system if by any chance you still have them on it.

Silverlight

Silverlight was meant to be a competitor for Adobe Flash, it is a WEB framework that enables rich media content inside your WEB browser. The issue is that it is not developed anymore and today's browsers do not support it. The only browser that actually can support it is internet explorer which itself is not supported and how there is practically 0 content on today's modern WEB that will require Silverlight, it is safe and recommended to remove it.

Adobe Flash

Speaking of Adobe Flash, you should remove it as well. Flash has stopped receiving support as of January 2021 and browsers have dropped support for it and even blocked it due to security issues. However, there still might be some local installation of Flash itself inside Windows along with the old Shockwave player that stopped receiving support in 2019. You should remove them both.

JAVA

Now this one is tricky, by itself JAVA does not present any security issues since browsers do not support it anymore and the desktop version is not really slowing down your computer. This one has simply put just another media runtime that is not used and simply takes up space and resources. However if you have some applications that you do use that rely on it (I can really just think of JAVA Minecraft at this point) leave it of course but in any other case, it is just purely not needed.

Quicktime

While we are at media runtime and stuff that just simply is not needed, Quicktime is one of them. Now this Apple Video player and codec is still pretty developed and active in Apple’s iOS environment, Windows version has not been updated since 2016 and it was discovered that it contains some critical vulnerabilities. Uninstall it and if you need a player that could play MOV files, just use a VLC player that can play them without any separately installed codec.

uTorrent

This one, the same as CCleaner was once a good application, as a matter of fact, it was the best torrenting application. Sadly it has fallen from its grace very low, from getting tons of ads in its interface to findings in 2015 that code of torrent client was packed with a crypto miner that used system resources of an installed computer to mine crypto without user’s awareness. You should uninstall this torrent client if you would like to get your PC back and not provide it for cryptocurrency mining for the company that developed it. Use qBittorrent or TIxati, open-source and free ones that have everything needed for any torrenting needs.

Toolbars and Browser extensions

There are a lot of toolbars for browsers and extensions that are malicious in nature or simply not updated providing security issues. It is very advisable to remove this as soon as possible.

WinRAR

WinRAR has gained its large popularity solely for the reason that you could download it from the official site like shareware and use it forever. The license never expired and you could use it indefinitely. Sadly not much has been improved in the application itself and it is slowly falling out in its range of what it can do. There are better open source and free options today like 7zip, PeaZip, ZIPvare, and more that are working the same as WinRAR if not even better.

Windows and manufacturers Bloatware

Yes, applications that come bundled with Windows and with some laptops that include manufacturers made software for different tasks like its own specific media players, calculators, etc. It is known that these applications are not better than their open-source rivals and there are too many of them including some that you will probably never use. It is the same as buying a new phone bundled with tons of applications that you do not need, did not ask for, and do not use. Delete all of them. Considering Windows there are also some Store application like Candy Crush Saga demo and other are safe to remove if not needed. That’s it, our advice for old and not needed applications so you can keep your PC safe and fast.

Prompted For A Product Key – What Is It?

Some Windows 7 or Windows 8/8.1 users are having a hard time upgrading to Windows 10 as they are being prompted for a product key. By default, the Windows 10 operating system does not require a product key and users should not be prompted for one, given you upgraded your computer from an activated Windows 7 or Windows 8/8.1 license or from the Windows 10 Preview build.
