How to fix Windows 10 Store Error 0x801901F7

When it comes to booting an operating system on a computer, one of the most essential pieces of software you can use is the UEFI. In fact, a lot of users now prefer to use UEFI instead of BIOS. It also depends on whether the UEFI or the BIOS is supported on the motherboard. Recently, a number of users reported an issue with UEFI where they were unable to find it under the Advanced Options screen where it’s supposed to be located. The missing UEFI Firmware settings in the Advanced Options could be caused by several reasons. It is possible that the access to the UEFI menu is blocked or it could also be due to the Extra Fast Startup feature being enabled. It is also possible that the operating system is installed in Legacy mode. There are several options to try to fix this issue. You need to check if your computer supports UEFI or you could also try to disable Fast Startup or bypass the Extra Fast Startup feature. You can also use a boot to UEFI shortcut as well as check the CMOS battery.

Option 1 – Try checking if your computer supports UEFI

The first thing you have to do is to verify if your computer supports UEFI. If your computer does not support UEFI, then it’s no wonder why you don’t see the UEFI Firmware settings in the Advanced Options.

Option 2 – Try turning off Fast Startup

• First, boot your computer in Safe Mode.
• Once your computer is booted in Safe Mode, tap the Win + R keys to open the Run dialog box and type in “control” to open the Control Panel.
• Next, click on the Hardware and Sound section and click on Power Options.
• Afterward, select the “Choose what the power buttons do” option from the left side menu pane.
• Now click on Change settings that are currently unavailable and uncheck the entry that says, “Turn on fast startup (Recommended)”.
• Then click on Save Changes and restart your computer and see if it has fixed the problem or not.

Option 3 – Try bypassing the Extra Fast Startup feature

As mentioned, the missing UEFI Firmware settings could be due to the Extra Fast Startup feature. To fix it, you have to disable this feature. All you have to do is tap and hold the Shift key and click on the Shutdown button from the Start button. This will boot your PC with the UEFI booting from the beginning and then use the hotkey for your motherboard to boot into the UEFI setup.

Option 4 – Try using a boot to UEFI shortcut

• Right-click on any empty space on your Desktop and select New > Shortcut.
• This will open a new mini window. And here, you have to type this in the text field: shutdown /r /fw
• After that, click on Next and name the desktop shortcut and then click on Finish.
• Next, right-click on the newly created shortcut and select Properties.
• Click on the Advanced button and select the “Run as administrator” option.
• Now click OK to save the changes made. Each time you execute this shortcut, your computer will automatically be booted to the UEFI Firmware Settings.

Option 5 – Try to check the CMOS battery

Another thing you can do is check the CMOS battery physically on the motherboard and see if it has to be replaced since a damaged CMOS battery can also cause the issue with the missing UEFI Firmware settings.

Option 6 – Set your computer from Legacy to UEFI

If applicable, you can try to set your computer from Legacy to UEFI to resolve the problem.

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: mbr2gpt.exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

California's Department of Fair Employment & Housing has widened its anti-discrimination lawsuit against Activision Blizzard and claims the publisher has been shredding vital documents relevant to the ongoing investigation. A recent report from Kotaku described the department as offering poorly paid, highly insecure positions, with a culture of hostility towards LGBTQ+ testers. The DFEH's rewording of "employees" to "workers" now hopes to take these contractors' experiences into account. "As a contract employee, I feel there's a lot of pressure to excel, impress, and move through the ranks as fast as you can before your contract ends and you're forced to go 3 months without income or find another job," Axios reports one worker saying. "I take pride in what I do, but it feels like it's never enough." Activision's contentious hiring of union-busting third-party law firm WilmerHale "directly interferes" with its own investigation, it says. By going to WilmerHale, Activision appears to be claiming that all work related to the investigation is privileged and can't be shared with DFEH. The suit also claims that Activision HR shredded documents related to "investigations and complaints", against its legal obligation to retain them during the investigation. The relevant parts of the updated lawsuit were shared by Axios reporters Stephen Totilo and Megan Farokhmanesh, the former also noting that the DFEH "fixed their misspelling of Bill Cosby's name". "DFEH is also informed and aware that documents and records have not been maintained as required by law or by the DFEH's Document Retention Notice," the complaint reads, "including but not limited to documents related to investigations and complaints were shredded by human resource personnel and emails are deleted thirty days after an employees separation."

Speculation and answer from Activision Blizzard

Blizzard employee Jessica Gonzalez suspects that the costs of fines associated with destroying these documents may have been an easier blow for Blizzard to take than any penalties drawn from their existence in helping the lawsuit go through. In an email to Kotaku, Activision denied the shredding allegations and issued a statement outlining steps it had taken to improve company culture—including the ousting of high-level executives like Blizzard president J. Allen Brack. The full statement reads: "Throughout our engagement with the DFEH, we have complied with every proper request in support of its review even as we had been implementing reforms to ensure our workplaces are welcoming and safe for every employee. Those changes continue today, and include:

•     Several high-level personnel changes
•     Revamped hiring and recruiting practices requiring diverse interview panels
•     Greater transparency on pay equity
•     Expanded and improved training and investigative capabilities for human resource and compliance staff
•     Created investigation teams outside of business units to support greater independence
•     Restructured divisions to support greater accountability
•     Enhanced review processes to include evaluation of managers by employees
•     Clear boundaries on workplace behavior with a zero-tolerance approach to harassment and other actions that diminish or marginalize.

"We strive to be a company that recognizes and celebrates the diverse talents and perspectives that lead to the creation of great, globally appealing entertainment. We have provided the DFEH with clear evidence that we do not have gender pay or promotion disparities. Our senior leadership is increasingly diverse, with a growing number of women in key leadership roles across the company. "We share DFEH’s goal of a safe, inclusive workplace that rewards employees equitably and is committed to setting an example that others can follow."

California and RIOT

Beyond Activision Blizzard, California's DFEH has also probed into League of Legends creator Riot Games, accusing the studio of dragging its heels over sexual harassment allegations dating back to 2019. Riot denied the allegations, telling us that it "will never retaliate against anyone for talking to any government agency".

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.

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.

If you receive an error code of “0x80073afc” in Windows Defender after you boot your Windows 10 computer or when you try to manually run Windows Defender, then it could be that the Windows Defender files are corrupted. In such cases, this error could also occur if there is third-party security software that interferes with the smooth functioning of this Microsoft Security Client. If you are one of the users who are currently facing this issue, then here are some suggestions you can check out to resolve the Windows Defender error code 0x80073afc.

Option 1 – Try to check the status of all the Windows Defender-related services

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “msc” in the field and hit Enter to open the Services Manager

  • Windows Defender Advanced Threat Protection Service – Manual
  • Windows Defender Antivirus Network Inspection Service – Manual
  • Windows Defender Antivirus Service – Manual
  • Windows Defender Firewall Service – Automatic

• You can right-click on each one of the listed services and then select Start to start them.
• And if some of the services don’t have their default values, just double-click on the Services to change the Startup types and select the correct option from the drop-down menu of the Startup type under the Properties box.
• Next, set up the Startup type of these services to Automatic and then click on the Start button if the services are not running yet.
• Now click on the Apply and OK buttons to save the changes made and then see if it fixed the problem or not.

Option 2 – Try to re-register the concerned DLL files

You could also try to re-register some Dynamic Link Library or DLL files on your computer as this could also help in fixing the Windows Defender error.

• In the Start search, type “cmd” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• After opening Command Prompt as admin, type the following commands one after the other:
  • regsvr32 dll
  • regsvr32 dll
  • regsvr32 dll
  • regsvr32 dll
• Once you’ve entered the commands given above, it will re-register the concerned DLL files in your system.
• Now restart your computer for the changes to take effect.

Option 3 – Try to use the Registry Editor

• Tap the Win + R keys to open the Run dialog box,
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
