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.

Windows Vista had in it animated wallpapers on desktop but sadly how they were heavy on system resources Microsoft abandoned the idea. Moving forward a couple of years later we have Windows 10 but still, we do not have live animated wallpapers. Since I am the kind of person who does not want to wait on Microsoft and now it is time to bring animated wallpapers back I am going to make one all by myself and you are welcome to join the ride and do the same for you as well. Enough talk, let's dive into how we can make animated wallpaper for our Windows 10.

Choosing the application

First, we will need some form of application which can we look at our animated wallpapers and since they are animations it means video, so we will need a video player and what better choice than a VLC player, an open-source light weighs all-format player. Get a VLC player from here and install it.

Finding video source

The next thing is to of course have some looping video that we will use as background. There are many sites and ways to get seamless loop videos, I use this youtube channel for my backgrounds. Altho you can use any video footage you want it is recommended that it is not too long, that it is hi-resolution so we do not have pixels on-screen, and if you can, get it as seamless since we do not want to see stutter when the video is lopped from the beginning. So hopefully you have desired video and VLC player installed.

Putting it all together

Copy the following code and paste it into your search bar in Windows to open the Startup folder, or navigate to the Startup folder yourself via file explorer if you know where it is. %appdata%\Microsoft\Windows\Start Menu\Programs\Startup Now, next thing is to copy and past the VLC shortcut into this folder so it is started when Windows is first time booted. Right-click on the shortcut and in the edit field paste this: "C:\Program Files\VideoLAN\VLC\vlc.exe" --video-wallpaper --qt-start-minimized --no-qt-fs-controller --repeat --no-video-title-show --qt-notification=0 "C:\videopath\filename.mp4" where "C:\Program Files\VideoLAN\VLC\vlc.exe" is the path where VLC is installed, point this to where you have installed it "C:\videopath\filename.mp4" is the path where you have your video that you wish to use as animated wallpaper. Please note also that in my case there is mp4 as an extension but it does not need to be mp4, just use any extension VLC can open and play.

Conclusion

And that's it, you have successfully made an animated background or live wallpaper on your Windows 10 computer. You can change your wallpaper anytime by editing shortcut and giving it a new path to a new video or simply overwrite the existing one with a new baring same name.

As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

• First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
• From there, click on the Edit button located under the Network name, Network password, and Network band.
• After that, set the Network band to be at 2.4 GHz and then click on the Save button.
• Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.
• Restart your PC and see if it helped in fixing the issue with the mobile hotspot.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.
