Fix 0x800F0825 update error in Windows 10

If you encountered an error message that says, “Unhandled exception has occurred in your application”, when you start your Windows 10 computer, read on as this post will guide you on how you can fix it. This kind of error usually appears in a Microsoft .NET Framework window and it mostly pops up as soon as you turn on your computer. Here’s the complete context of the error message:

“Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.”

When this error occurs, your computer may freeze or display other suspicious behavior at times. Either way, there are several options you can check out in this post to resolve this issue, so read on. This kind of error could be caused by several factors. It could be due to your antivirus program or other third-party programs installed on your computer. It is also possible that the installation of the Microsoft .NET framework id corrupted or some of its installation files are corrupted. Thus, to fix the error, there are a few suggestions you need to follow such as:

Option 1 – Try to temporarily disable your anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive in your computer. There are times when you encounter problems like the “Unhandled exception has occurred in your application” error due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program in the meantime and check if it fixes the error or not.

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Once your computer has restarted, check if the error is now gone. If it is, then the culprit is some third-party program. Thus, you have to enable the third-party programs one by one to find out which one of them is causing the the “Unhandled exception has occurred in your application” error.

Option 3 – Try to run a System File Checker scan

System File Checker or 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 that might be the cause why you’re getting the “Unhandled exception has occurred in your application” error. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• 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.

• Now restart your computer and see if the problem is fixed or not.

Option 4 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual check especially if you are getting this issue of abnormal program termination.

• Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.
• Download and install or Update DirectX – As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.
• Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
• Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

Stable Diffusion is a machine learning model developed by Stability AI to generate digital images from natural language descriptions. The model can be used for different tasks like generating image-to-image translations guided by text prompts and upscaling images.

Unlike competing models like DALL-E, Stable Diffusion is open source and does not artificially limit the images it produces. Stable diffusion was trained on a subset of the LAION-Aesthetics V2 data set. It can run on most consumer hardware equipped with a modest GPU and was hailed by PC World as "the next killer app for your PC".

Since Stable Diffusion is run locally and not in the cloud, as mentioned there is no limit to the number of images that you can produce but in order to use it you will have to get down a little dirty with setting your PC environment for it since it is not really an application, it is a command line text based descriptor that will use python to generate your images, so there is no install nor GUI.

In this guide, we will show you how to both install and run Stable Diffusion on your local PC so you can start producing some cool images all by yourself.

Hardware and software requirements

Make no mistake, Stable Diffusion will not run on a potato PC, in order to harvest the power of AI-generated imagery this is what you will need:

• A GPU with at least 4GB of VRAM
• 10GB of hard disk space
• Python and libraries (Miniconda3 installer will install everything you need)
• The Stable Diffusion files
• Git
• Any OS (Windows, Linux, macOS)

Installing components

For this tutorial, we are covering the installation and running of Stable Diffusion on Windows PC. The steps presented here are presented in a way that installation can be performed on any operating system but precise instructions will be for Windows OS.

GIT

The first thing to do is to install GIT. It is a tool that will let you easily maintain and install repos from the internet. to install it go to: https://git-scm.com/ and click on download. Follow the instructions for your version of the operating system. If you are a developer you are familiar with GIT and if you already have it installed you can skip this step.

One thing that is important when installing GIT locally is to select to use it via the command line (the second option that says "Git from the command line and also from 3rd-party software").

Miniconda3

Now when we have GIT installed, next thing is to use Miniconda3 to install python and all required libraries that are needed. Get the installer at: https://docs.conda.io/en/latest/miniconda.html

Miniconda3 is basically an easy installer so you do not have to install tons of stuff manually from different websites and sources, it is nicely packaged in the installer that will take care of everything.

Stable Diffusion

After the previous two steps, we are ready now to actually install Stable Diffusion. Go to https://huggingface.co/CompVis/stable-diffusion#model-access and install the latest library (as of the writing of this article currently it is stable-diffusion-v1-4-original, the last one on the right), the library is almost 5GB in size so be prepared for big download.

After installing stable diffusion's latest library it is time to update it to the newest version. You can download ZIP from GIT HUB https://github.com/CompVis/stable-diffusion

Once downloaded click on the Windows start button and type in Miniconda3 and click on open. Create a folder and name it how you want on a drive of your choice. For this example, we will install it all in disk C under folder AI_art, follow the instructions below but use your own names and destination instead. Do not close Minicoda3 after typing commands!!!

cd c:/
mkdir AI_art
cd AI_art 

Extract GitHub files that you have downloaded into your new folder and get back to Minicoda3 and type the next commands:

cd C:\AI_art\stable-diffusion-main
conda env create -f environment.yaml
conda activate ldm
mkdir models\ldm\stable-diffusion-v1

Let the whole process finish, some files are large and it might take a while. After the whole process is finished and completed, copy the checkpoint file that you have downloaded into: C:\AI_art\stable-diffusion-main\models\ldm\stable-diffusion-v1

After the file is copied rename it to model.ckpt and you are finished.

Running Stable Diffusion

The created environment is needed in order to actually use Stable Diffusion to create images. Each time you want to use it you will have to run it, so go into Miniconda3, and inside it type:

conda activate ldm
cd C:\AI_art\stable-diffusion-main

after we are inside the folder call the script with the parameters:

python scripts/txt2img.py --prompt "TXT DESCRIPTION OF IMAGE THAT YOU WANT TO CREATE" --plms --n_iter 5 --n_samples 1

and that's it, your image is created and it is located in C:\AI_art\stable-diffusion-main\outputs\txt2img-samples\samples

Windows comes with a built-in backup solution. However, if it failed because of an internal error, you will encounter an error message saying, “The backup application could not start due to an internal error, Server execution failed (0x80080005)”. When you get this kind of error, it means that it did not start and the process failed with a Server execution error. If you got this kind of error worries not for this post will guide you in fixing the problem in your Windows 10 computer. The Windows Backup service is an excellent feature in Windows that only works on the NTFS file system and if you want to use this make sure that you have formatted your files system to NTFS. It is performed by the Volume Shadow Copy, all you have to do is right-click on any folder and if you see the “Previous versions” option, this means that a backup process runs from time to time and can bring back old files when needed. To resolve the “The backup application could not start due to an internal error”, here are two suggestions you can check out.

Option 1 – Check if the Volume Shadow Copy service is running and restart it

The first thing you need to do is check if the Volume Shadow Copy service. To do that, refer to the following steps:

• Click on Start and type “cmd” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, type “net stop sdrsvc” and hit Enter to execute the command in stopping the Volume Shadow Copy service.
• Next, type the “net start sdrsvc” command and hit Enter to start the service again.

Note: You can also restart the service using the Windows Services Manager.

• 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 “services.msc” in the field and hit Enter to open the Services Manager.
• From there, look for the Volume Shadow Service (sdrsv) from the list of services. Its Startup type should be set to Manual by default.
• Restart the service and if you don’t encounter any error while you turn it on, re-run the backup service and see if the backup process runs successfully.

Option 2 – Try to run the Volume Shadow Copy Service in a Clean Boot State

If the first option didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run Windows Backup again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to run the Volume Shadow Copy service again and see if the process goes smoothly.

Note: You might also want to delete all the files in the backup solution if you want to start fresh with the backup solution. Just go to C:/System/Volume/Information/Windows Backup and take ownership of the folder. After that, make sure to stop the Volume Shadow Copy service and then delete all the files inside it.

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.

A runtime error is commonly an error that's created after the PC is operating software and encounters a problem of some form. For instance, a runtime error like run-time error code 7 reveals an "out of memory" dilemma.

Solution

Error Cause

Run-time errors are normally brought on by clashes with TSR (Terminate and Stay Resident) applications or additional operating applications, software problems, storage problems, or pc viruses.

Troubleshooting a Run-time Error

First, enter the run-time error signal into a search engine to see what info you will get about the precise runtime issue you are receiving. Next, end - job all running applications and TSRs to make sure these aren't the origin of the issue. You can certainly do so by obtaining the job manager by striking Control Alt Delete.

In case your issue is regularly occurring with a unique program, go to that system programmer's site and obtain any upgrades and patches. If unavailable, try uninstalling the application involved and reinstalling it.

In the event the issue is occurring with the os, you may consider reinstalling it although it is a huge commitment. A much better idea would be to try a fix for both Windows XP or Windows 2,000. It is possible to fix and scan files by typing : sfc / scannow, heading to the Begin switch, Run, and then pushing enter. Make certain to put an area between sfc and the reduce.

You might have an equipment or storage dilemma if these measures have not resolved your run-time errors. If that is the situation, contact the support of the application under consideration for potential support accompanied by the pc or motherboard manufacturer.

Many run-time problems can be solved by upgrading the application that's creating the problem. This is only because the programmer's frequently releasing patches and improvements for their applications as insects are found and repaired.

Storage problems may frequently be fixed by rebooting the pc. Consider a reboot a short-term repair. Rebooting clears the memory but in case your COMPUTER does not have adequate memory for your applications you're operating, or sufficient hard-drive space you'll immediately run out of memory again. Something less than this sum may cause memory issues since the computer's swap file isn't in a position to expand in dimension as required.

To assess the quantity of free area, available My Computer and right-click on the HDD, generally the D: drive. Select Attributes in the menu and see the disc's ability. Perform the disk clean-up function by following prompts and pressing the Disk Clean-up button, if the room is reduced.

You may be getting run-time errors, in case your storage chip is really failing. Eliminating and changing the awful memory chip will solve the difficulty. If you're encountering other runtime-related errors, like an install runtime issue, try cleaning away the portions of the registry with some software solution. 

What is Search.schooldozer.com? And how does it function?

Search.schooldozer.com is a browser extension that functions as a search engine. It is developed and maintained by “Schooldozer”. It claims to improve users’ browsing experience by providing them with improved search results. However, it does not really do the things it claims to do. In fact, they’re quite the opposite ones – instead of improving the browsing experience, it makes users’ browsing experience unsafe and full of sponsored content. This is in contrast to what it states in its Privacy Policy:

“Install applications the easy way and without the hassle, using the Schooldozer downloader. The Schooldozer platform stems from years of experience with installing applications, resulting in a highly optimized process, yielding faster downloads, better user experience, and more successful installations.”

In addition, once installed Search.schooldozer.com is installed, it will change the default settings of a browser such as the default search engine, homepage, and new tab page.

Error Code 0x80070070 - What is it?

Error code 0x80070070 can be presented when there is not enough drive space on the computer to install updates. It is possible to uninstall apps that are not often used, or you may delete or archive files that are no longer needed, you may even add on some removable storage space to free up the internal memory of the computer. The computer needs a significant amount of internal memory in order to be able to update the operating system properly. When the computer fails to have the amount of memory that is needed to perform the update, the error code 0x80070070 will be presented. If this error message is not resolved, your computer might be opened to other error messages, including error code 0x80072EE2.

Common symptoms include:

• Windows cannot install updates properly.
• You might not be able to install any additional programs or apps onto the computer.
• When you check the memory of the computer, it may be very near its full capacity.

Solution

Error Causes

The Windows 10 upgrade error is caused by varying factors including a lack of computer space or resources, malware or virus infestation, or a clogged registry on the computer.  The error code 0x80070070 will present itself when there is not enough free space on the computer to perform the necessary updates on the computer. Too many apps or programs downloaded onto the computer, too many photos, or too much music may also contribute to the lack of storage space on the computer, thus contributing to the error, and the computer not being able to install the updates to the operating system properly.

Further Information and Manual Repair

There is not a lot of information regarding this error code, but there are a few methods to repair it when it does present itself. There are practical and manual steps that can be taken when trying to get the PC up and running. The primary way to solve this problem is to free up disk space and there are several ways to do this. Please do note that if these methods seem confusing or too complicated, do contact a Windows repair technician so that they may properly correct the problem. You will need to know for sure that it is error code 0x80070070 that you are dealing with so that these options are the best bet for fixing it.

Method One: Disk Cleanup

It is important to know how much space there is on the computer to start with prior to trying to free up any space. Use the free program on the computer called the Disk Cleanup tool. This will save time and free up some hard drive space while optimizing the computer to work better.

From the Start menu, browse to the Explore option, and then select This PC. Right-click on the C drive, and then select Properties. Select Disk cleanup. From here, select the options that you would like to clear. Make sure that the recycle bin is emptied of any temporary files or any error logs. Once done, select Okay.

Use this same process to clear the system files after an update from Windows, as they may still have files from the old operating system in place.

Method Two: Remove Unwanted Apps

Go through your computer and remove any unwanted apps that are present. There are sure to be some that you do not use or do not want.

Follow these steps: From the Start menu, select Settings. Then, select System, Apps, and Features. When you have found the program that you would like to uninstall, select it and then select Uninstall. NOTE: some apps that are built into Windows do not have the capability to be uninstalled. Once you have selected Uninstall for the app or program, follow all directions that appear on the screen.

Method Three: Cloud Storage

If there are a lot of media, photos, documents, videos, and the like that are not used on a regular basis, try out cloud storage. These files will still be in your possession and will be able to be accessed from anywhere. There are many applications or websites that cater to this.

Method Four: External Storage Options

If none of the above methods work, add more storage. To acquire more storage, you can incorporate devices such as SD cards, USB flash drives, and even external hard drives.

Method Five: Use An Automated Tool

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.

This post will guide you on what to do if your keyboard shortcuts or hotkeys are not working on your Windows 10 computer. A lot of users use hotkeys as they make things easier for them as they use their computer. However, there are instances when these hotkeys suddenly stop working. It’s actually one of the most common problems with keyboards. And so to resolve this problem, you can try out some suggestions prepared on this post.

Option 1 – Clean the keyboard keys physically

Your keyboard might not be working properly due to some dirt or other corrosion. First, you need to shut down your computer and then unplug the keyboard if you are using a desktop computer and then prepare it for cleaning. After that, use a small cotton ear cleaning tool to get between the creases and clean them. You can dip it slightly in alcohol to make it more efficient in cleaning dust and dirt. And if you can, you have the option to pull apart the keyboard completely and then wipe away all the corrosion from the inside. Once you’re done, put the keyboard back together and then plug it back into your PC. Now turn your PC on and check if the hotkeys are now working.

Option 2 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try connecting the keyboard to a different USB port

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion.

Option 4 – Uninstall previously installed keyboard software

If you have been previously using another keyboard, it might be better if you make sure that the software for the old device has been removed since there are instances when multiple software can cause problems due to similarities in actions.

Option 5 – Update the keyboard driver

You can also update the keyboard driver to fix the problem. There are cases when an outdated or corrupted driver can fix the problem. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, look for the keyboard driver and click on it.
• Next, right-click on the keyboard driver and select the Update driver option.
• After that, click the “Search automatically for updated driver software” option to proceed.

Option 6 – Reinstall the keyboard driver

If updating the keyboard driver didn’t help, then you might want to reinstall it. How? Follow the steps below.

• Tap the Win + R keys to launch Run.
• Type in 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 keyboard driver, right-click on it and then select “Uninstall device”.
• After that, unplug the device and restart your PC.
• Then plug your device back in. Assuming your device is connected to your PC, open the Device Manager again.
• Next, click on the Action button and click the Scan for hardware changes button. That should fix the problem.

Note: You could also completely uninstall the driver and go directly to the manufacturer’s website and download the latest driver for your hardware and then install it.

Option 7 – Enable Human Interface Device (HID) Service

Another thing to consider is the Human Interface Device Service. If this service is disabled, then no wonder why your hotkeys are not working. Thus, you need to enable this service. Refer to the following steps to do that:

• Tap the Win + R key to launch the Run dialog box.
• Then type “services.msc” in the field and hit Enter to open Services.
• After opening Services, scroll down until you see the Human Interface Device service.
• Double click on HID and make sure that its Startup Type is set to “Automatic” and then click OK.

The Windows Defender Advanced Threat Protection service is the one that protects your computer from advanced threats by monitoring and reporting security events that happen on your computer. This is why you have to make sure that this, as well as other required services in Windows Defender, are set to their default values and are started. To do so, follow these steps:

• 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 “services.msc” in the field and hit Enter to open the Services Manager
• After opening the Services Manager, look for the following services and make sure that their Startup type is set to their default values:
  • 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.

• Next, navigate to this registry path: HKLMSoftwarePoliciesMicrosoftWindows Defender
• From there, look for the “DisabledAntivirus” and “DisableAntiSpyware” DWORDS from the right pane and change each one of their values to “0”. On the other hand, if you don’t see any of these DWORDS, you can create them instead and give each one of them a 0 value.
• To create a DWORD, simply right-click on any empty space and select New > DWORD. Then name them both as “DisabledAntivirus” and “DisableAntiSpyware”.
• Afterward, set the value of the newly-created DWORDS to 0.
• Now exit the Registry Editor and reboot your PC to apply the changes made and then check if it has fixed the error in Windows Defender or not.
