Fix Windows Update error 0x80244022

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. This is why security experts regard this browser extension as a browser hijacker and a potentially unwanted program. The modification of the browser's settings allows it to control users’ browsing by redirecting them to sponsored sites as well as deliver sponsored content from its affiliated sites in order to gain profit via pay-per-click marketing. And if you think that the ads it displays are harmless, think again for some of these ads can redirect you to suspicious websites that might contain harmful content. What’s more is that this browser hijacker can also keep track and monitor all your browsing activities in order to obtain your browsing data like search queries, what sites you always visit, browsing history, browser type, OS version, and so on. The information collected is then used and may even be shared with its affiliated third parties to deliver more customized and personalized advertisements.

How is Search.schooldozer.com distributed over the web?

Like a typical browser hijacker, Search.schooldozer.com is distributed using the software bundling method where several unknown and unwanted programs are bundled in a software package.

The latest security vulnerability was discovered inside both Windows 10 and Windows 11 letting any user access admin privileges inside the operating system. This can, of course, be used by a potential attacker to get full control of the system. The problem lies in Microsoft's security rules assigned to the Windows Registry and the Security Account Manager. Both for some reason have reduced restrictions allowing any local user to fully access the files without administrator privileges. The problem is even more amplified if we think about Security Account Manager which includes all account data including the passwords of all users using the same PC. This can provide a potential attacker with all information and let them log on into the administrator account for full control. Microsoft is aware of the matter and is tracking it with code CVE-2021-36934, and includes a complete workaround for the issue, which includes restricting access to  %windir%\system32\config and deleting any restore points or Shadow volumes that were created before that point until the hole is plugged with an official security patch.

What is PyLocky ransomware? And how does it execute its attack?

PyLocky ransomware is a file-locking malware created in order to lock important files and demand ransom from victims in exchange for data recovery. This new ransomware uses the .lockymap extension in marking the files it encrypts. It starts to execute its attack by dropping the following malicious payload in the system:

Name: facture_4739149_08.26.2018.exe SHA256:8655f8599b0892d55efc13fea404b520858d01812251b1d25dcf0afb4684dce9 Size: 5.3 MB

After dropping its malicious payload, this crypto-malware connects the infected computer to a remote server where it downloads more malicious files and places them on system folders. It then applies a data gathering module used to gather data about the user and the computer. The malicious files that were downloaded earlier along with the data obtained are used for another module called stealth protection. This allows PyLocky ransomware to execute its attack without detection from any security or antivirus programs installed in the system. It also modifies some registry keys and entries in the Windows Registry such as:

• HKEY_CURRENT_USERControl PanelDesktop
• HKEY_USERS.DEFAULTControl PanelDesktop
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
• HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce
• HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

Once all the modifications are carried out, PyLocky ransomware will begin encrypting its targeted files using a sophisticated encryption cipher. Following the encryption, it adds the .lockymap extension to each one of the encrypted files and releases a ransom note named “LOCKY-README.txt” which contains the following content:

“Please be advised: All your files, pictures document and data has been encrypted with Military Grade Encryption RSA ABS-256. Your information is not lost. But Encrypted. In order for you to restore your files, you have to purchase a Decrypter. Follow these steps to restore your files. 1* Download the Tor Browser. ( Just type in google “Download Tor“ 2‘ Browse to URL: http://4wcgqlckaazungm.onion/index.php 3* Purchase the Decryptor to restore your files. It is very simple. If you don’t believe that we can restore your files, then you can restore 1 file of image format for free. Be aware the time is ticking. Price will be doubled every 96 hours so use it wisely. Your unique ID : CAUTION: Please do not try to modify or delete any encrypted file as it will be hard to restore it. SUPPORT: You can contact support to help decrypt your files for you. Click on support at http://4wcgqlckaazungm.onion/index.php”

How does PyLocky ransomware spread over the web?

PyLocky ransomware spreads using malicious spam email campaigns. Creators of this threat embed an infected attachment to spam emails and send them using a spambot. Crooks may even use deceptive tactics to trick you into opening the malware-laden immediately which is something you must not do. Thus, before opening any emails, make sure that you’ve thoroughly checked them. To successfully obliterate PyLocky ransomware from your computer, refer to the removal guide laid out below.

• Step 1: Launch the Task Manager by simply tapping Ctrl + Shift + Esc keys on your keyboard.
• Step 2: Under the Task Manager, go to the Processes tab and look for the process named facture_4739149_08.26.2018.exe and any suspicious-looking process which takes up most of your CPU’s resources and is most likely related to PyLocky ransomware.
• Step 3: After that, close the Task Manager.
• Step 4: Tap Win + R, type in appwiz.cpl and click OK or tap Enter to open Control Panel’s list of installed programs.
• Step 5: Under the list of installed programs, look for PyLocky ransomware or anything similar, and then uninstall it.
• Step 6: Next, close the Control Panel and tap Win + E keys to launch File Explorer.
• Step 7: Navigate to the following locations below and look for PyLocky ransomware’s malicious components such as facture_4739149_08.26.2018.exe and LOCKY-README.txt as well as other suspicious files, then delete all of them.

%TEMP% %WINDIR%System32Tasks %APPDATA%MicrosoftWindowsTemplates %USERPROFILE%Downloads %USERPROFILE%Desktop

• Step 8: Close the File Explorer.
• Step 9: Tap Win + R to open Run and then type in Regedit in the field and tap enter to pull up Windows Registry.
• Step 10: Navigate to the following path:

HKEY_CURRENT_USERControl PanelDesktop HKEY_USERS.DEFAULTControl PanelDesktop HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce

• Step 11: Delete the registry keys and sub-keys created by PyLocky ransomware.
• Step 12: Close the Registry Editor and empty the Recycle Bin.

Try to recover your encrypted files using the Shadow Volume copies Restoring your encrypted files using Windows Previous Versions feature will only be effective if PyLocky ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot. To restore the encrypted file, right-click on it and select Properties, a new window will pop up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.

Usually when online service is not working or when something goes wrong online it is DNS, well that is what most of the time is the case. And yes, DNS or Domain Name Server seems to be an issue with Facebook being completely down along with Instagram and wassap. The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP. Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted, "By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform." Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things. Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages: "DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures." Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface. Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally." Technicians on site don't know how to do that and senior network administrators aren't on site. It seems that it will all be down for a couple of more hours before the issue is resolved.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

If you continuously encountered the “VirtualBox FATAL: No bootable medium found, System halted” error when you try to install Windows 10 in VirtualBox, read on as this post will give you some potential fixes to resolve the problem – you will be guided on how to choose the ISO image to fix this error in VirtualBox. This kind of error is a very common one especially if you have a corrupted ISO file or if you have not selected an ISO file for your virtual machine. Like pointed out, this error pops up when you have a corrupted ISO file or if the ISO file is not attached to the virtual machine. You have to select the ISO file while you create the virtual hard disk, else, you will most likely face this problem, and to fix it, you need to download fresh Windows ISO, create a new IDE Controller, assign Windows ISO to the IDE Controller and then boot your virtual machine. For detailed steps, follow the instructions below but before you start, make sure that you have a valid and uncorrupted Windows ISO. Step 1: First, you need to open the VirtualBox program on your computer and select the virtual machine. Step 2: Next, click on the Settings button or you can also right-click on the virtual machine and select Settings from the context menu. Step 3: Once you’re in the Settings panel, go to the Storage section and from there, create a Controller: IDE. Step 4: To create a Controller: IDE, click the Add new storage controller icon and select the “Add IDE Controller” option. Step 5: After that, click the Add optical drive icon and click on the Choose disk button. You will then see all the attached and non-attached ISO files. However, you have to add the new ISO file that you just downloaded. Step 6: To add the new ISO file, click the Add button and select the ISO file and then select the .iso file from the Non Attached section. Step 7: Now click the Choose button and afterward, make a checkmark in the Live CD/DVD checkbox and then select the IDE Primary Master from the drop-down menu of the Optical Drive. Step 8: Once you’re done, save the changes made and try booting into your virtual machine again.

If you suddenly encountered an error when you try to run the Windows Sandbox that says, “Windows Sandbox failed to start, Error 0xc030106, The virtual machine or container exited unexpectedly”, read on as this post will guide you on what you can do to resolve the problem. According to security experts, this kind of error in Windows Sandbox is due to some issues with the supporting virtualization component. It could also be caused by other factors and to fix it, there are several potential fixes you need to check out. You can try running the Windows Sandbox as an administrator. You should also make sure that all the supporting processes are running properly, as well as try to install any pending Windows Updates.

Option 1– Try to run Windows Sandbox as an admin

• In the Start Menu, scroll down until you see the entry for the Windows Sandbox.
• Then right-click on it and select More and then select the “Run as administrator” option to open it with admin privileges.
• Next, if a User Account Control or UAC prompt pops up, just click on Yes to proceed.
• You should now be able to open the Windows Sandbox without the error. However, if the error persists, proceed to the next given options below.

Option 2 – Ensure that all the supporting processes and services are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, from the list of services, look for the following services in the given order:
  • Network Virtualization Service

  • Hyper – V Virtual Machine
  • Hyper – V Host Compute Service
  • Container Manager Services
• After you find the aforementioned services, restart each one of them.
• Once done, try to open the Windows Sandbox again and see if the error is fixed or not.

Option 3 – Try to install any pending Windows Updates

If the second option still didn’t work, then you might want to check Windows Updates on your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

If you are trying to install or reinstall a program on your Windows 10 computer but encountered an error instead that says, “Fatal error, Installation fails, Installation ended prematurely because of an error”, then you’ve come to the right place as this post will guide you how you can fix it. This kind of error is most likely caused by some files that may have been left behind by the previous installation of the program. Each time a program is uninstalled, it leaves behind its files and if the uninstallation process wasn’t completed properly, then it would result in errors like the

“Fatal error, Installation fails, Installation ended prematurely because of an error”.

Moreover, this kind of error is a generic one that can also occur with any software reinstallation or installation. And to fix this error, there are several suggestions you must check out. You can try to install or reinstall the program in a Clean Boot State or restart the Windows Installer Service. You could also try to re-register the Windows Installer Service or re-register the VBScript.dll file.

Option 1 – Install or reinstall the program in a Clean Boot State

It is possible that there are some third-party applications in your computer that are preventing the program from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• 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” checkbox 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” checkbox.
• 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.)
• After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the program again.

Option 2 – Try to restart the Windows Installer Service

The next thing you can do to fix the problem is to restart the Windows Installer Service. To do this, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and then hit Enter to open the Windows Services Manager.
• Next, look for the Windows Installer service among the list of services shown.
• Once you found it, right-click on it and open its Properties.
• From there, click on the Stop button and then click on the Start button.
• But if it isn’t running, then just click on the Start button.

Option 3 – Try to unregister and re-register the Windows Installer Module

• Tap the Win + R keys to open the Run dialog box.
• Then type the “msiexec /unregister” command and hit Enter to unregister the Windows Installer Module.
• Next, type the “msiexec /regserver” command and hit Enter to re-register the Windows Installer Module.
• Now restart your computer and see if unregistering and re-registering the Windows Installer Module fixed the problem or not.

Option 4 – Try to re-register the vbscript.dll file

You may have to re-register the vbscript.dll file using the regsvr32.exe before you can successfully install the program and fix the error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the 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 regsvr32.exe vbscript.dll 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.
• 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.

If you suddenly encountered an error that says, “The Task image is corrupt or has been tampered with”, along with an error code of 0x80041321, read on as this post will guide you on what you can do to resolve this problem in your Windows 10 computer. According to security experts, this kind of error has something to do with a corrupt scheduled backup task wherein each time the task service plans to execute a task, it validates a few things. And if it finds any issue with the integrity or corruption in the registry, it will mark those tasks as corrupt and throws the error 0x80041321. There are several options you can check out to fix the problem. You can try using the Registry Editor to edit and fix the corrupted tasks or you could also delete the schedule keys or the WindowsBackup file, as well as try deleting the task from the Task Scheduler or refresh the User_Feed_Synchronization. But before you of these potential fixes, make sure that you check every option and verify if it’s not associated or trying to run a file which it should not. In addition, make sure that you create a System Restore point as well so that you can undo any changes you will be making if anything goes wrong. Once you have these things covered, refer to each one of the options provided below.

Option 1 – Try to use the Registry Editor to edit and fix corrupted tasks

The first thing you can do to fix the problem is to edit those tasks via Registry Editor, as well as fix the corrupted ones in System32. Before you proceed, keep in mind that since you are dealing with the Backup triggered by the Task Scheduler, you can find the entries for the tasks in different locations. You can find the Task Scheduler at Task Scheduler Library > Microsoft > Windows > Windows Backup, whereas, you can find it in this path in the Registry Editor, HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows NT CurrentVersion Schedule WindowsBackup AutomaticBackup. On the other hand, you can find the Windows System folder at C:/Windows/System32/Tasks/MicrosoftWindows/WindowsBackup. You need to ensure that the name of the task name is the same as everywhere and take note of the name. Once you have these covered, follow the steps below.

• Tap the Win + R keys to open Run and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTreeMicrosoftWindowsWindowsBackup
• From there, take note of the GUID value in the ID entry of the task under the AutomaticBackup and Windows Backup Monitor folder.
• After that, you have to remove the task registry entries related to the ID from these locations
  • HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
  • HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
  • HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
• Once done, you have to create a temporary copy of the corrupted task file by going to this location: C:/Windows/System32/Tasks/MicrosoftWindows/WindowsBackup
• From there, look for the AutomaticBackup and Windows Backup Monitor tasks and copy them to a location where you can keep them safe.
• Next, you have to fix the corrupted task by deleting it from this location: C:/Windows/System32/Tasks/MicrosoftWindows/WindowsBackup
• After that, you have to recreate the task by going to Task Scheduler > Microsoft > Windows> Windows Backup.
• Now click on the Action menu and on Import task and navigate to the backup files and import them.
• Once you’ve created the tasks, run them manually and see if the error is now fixed.

Option 2 – Try to delete the Schedule keys in the Registry

• Launch the Registry Editor and go to this key: HKLMSOFTWAREMicrosoftWindows NTCurrent VersionSchedule
• From there, delete all of its sub-keys.
• Once done, exit the Registry Editor and check if the Backup Tasks are now working.

Option 3 – Try to remove the WindowsBackup file

The next thing you can do to fix the problem is to remove the WindowsBackup file if the first two options didn’t work. It is possible that the problem has something to do with corrupted Task files. The task files are XML files that include parameters, programs to use, and many more. If any of these files end up getting corrupted, the task scheduler will have trouble running it and will throw the “The Task image is corrupt or has been tampered with” error.

• To delete it, go to C:WindowsSystem32TasksMicrosoftWindowsWindowsBackup.
• From this location, get rid of all the files. You could also these files via Command Prompt using the DEL command.
• Once done, go to the Backup and Restore in the Control Panel and set up the Windows Backup again.

Option 4 – Try to delete the task from the Task Scheduler

If you don’t want to delete the files from Windows Explorer, you can delete them instead via Task Scheduler.

• Open the Task Scheduler and go to Task Schedule LibraryMicrosoftWindowsWindowsBackup.
• From there, delete both of the tasks and set up Windows Backup again.
• Once done, go to the Task Manager and run the AutomaticBackup task again and see if it works.

Option 5 – Try to restart the Task Scheduler service

As mentioned, it is possible that the Task Scheduler service could be disabled. You could have disabled it when trying to enhance your computer’s performance and whatnot. Thus, you need to verify if it’s running or not and then restart it.

• First, you need to tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “services.msc” in the field and click OK or tap Enter to open the Windows Services Manager.
• You will see a list of Services and from there, look for the Task Scheduler service and double click on it.
• After that, go to the General tab and click on the Startup Type options and then select “Automatically” from the given list.
• Click on the “RUN” option and select the “Restart the Service” option.
• And click on the “After Second Failure” option and then select the “Restart-Service” option again.
• Now click on the “After Subsequent Failures” tab and select the “Restart the Service” option.
• Finally, click on the Apply and OK buttons and then run the Task Scheduler and see if the issue is now fixed.

Option 6 – Try refreshing the User_Feed_Synchronization

According to security experts, enabling and disabling the User Feed sync also known as the User_Feed_Synchronization task can help resolve the problem.

• Tap the Win + X keys and select the PowerShell (admin) option from the menu.
• Next, type the “msfeedssync disable” command and tap Enter.
• Repeat the same process but this time run the “msfeedssync enable” command.
