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.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• 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.

If you recently made some changes in your Windows 10 computer using the Group Policy Editor but they were not reflected and you got errors instead, it could be that your Windows computer wasn’t able to read the Group Policy file (registry.pol). To resolve this kind of issue, you have to repair the potentially corrupted Group Policy using the options given in this post. .As you know, Group Policy is a feature in the Microsoft Windows Active Directory which allows an admin to make changes in the features on Windows PCs that are on the network. So if the modifications you just made weren’t successfully applied, then there could be something wrong with the registry.pol file on the client or it could also be that the Group Policy folder is missing. To fix this issue in the Group Policy, you need to refer to the given suggestions below and make sure that you have admin privileges as you execute them.

Option 1 – Try to delete or recreate the missing registry.pol file

The entire settings of the Group Policy are stored in the registry.pol file so if it went missing, all the changes you make will not be reflected. The good thing is that you can recreate it but if the file exists and is corrupted, you need to delete it first before you recreate it.

• First, go to the C:/Windows/System32/GroupPolicy/Machine location.
• And from there, check if the registry.pol file exists or not. If it’s there, just delete it permanently by tapping the Shift + Delete keys.
• Now it’s time to recreate the file. Just open Windows PowerShell with admin privileges by tapping Win + X + A keys.
• After opening PowerShell, type this command: gpupdate /force
• The command you entered will recreate the registry.pol file and will refresh the Group Policy. Restart your computer.

Option 2 – Try recreating the secedit.sdb file

The security settings of Group Policy are stored in the secedit.sdb file so if you made some changes to security and they weren’t reflected, you can try to delete and recreate the secedit.sdb file instead of deleting the Group Policy file. All you have to do is navigate to the C:/WINDOWS/security/Database folder and look for the secedit.sdb file and rename it or move it to another folder. After that, restart your computer. Once your computer has restarted, the secedit.sdb file will be created again.

Option 3 – Try to reset the Group Policy to default

You can also try to reset the Group Policy back to its default state. There are several ways you can do that. You can either use the gpupdate or the secedit command in the Windows PowerShell to do that. Resetting the Group Policy will resolve any issues that could be caused by its current settings.

Option 4 – Try to perform System Restore

System Restore can also help resolve the Group Policy issue. It could be that prior to the issue, you’ve made some changes in the system that might have affected the Group Policy. To undo these changes, perform System Restore.

• First, tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Use the DISM tool

You can also try running the Deployment Imaging and Servicing Management or DISM tool. This tool will repair the Windows System Image as well as the Windows Component Store in your Windows 10 computer. So if there are any missing or corrupted folders and files, the DISM tool can restore and repair them. As a result, any system consistencies and corruptions will be fixed. To run this tool, follow these steps:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth

• Once you’ve executed the commands given above, restart your computer.

We’ve already covered disabling Security Questions If you want to disable Security Questions on your Windows 10 computer then you’ve come to the right place as this post will guide you in doing exactly that. In this post, you will be disabling Security Questions using a PowerShell script. This PowerShell script is called “Update-AllUsersQA”. It is designed to remove or disable the security questions and answers for local users on a Windows 10 computer. It lets administrators take control of the security questions in the environment and at the same time minimizes the risk that comes with them. If a user has a Microsoft account that’s configured to sign in to Windows 10 then he will not probably notice the Password Recovery questions. On the other hand, if he has a chosen local account for installing Windows, he will e prompted to create three security questions that can be used to reset the password and log into the Windows 10 account in case there is any misfortune. However, if you do not have much use for these Security Questions, then you can definitely have them disabled using a simple PowerShell script which you can download from GitHub. For more details on how to disable security questions in a Windows 10 machine, refer to the steps provided below. Step 1: You need to first download the .ps1 file from the GitHub repository. Step 2: Once you’ve downloaded the file, open the PowerShell window with admin privileges. Step 3: After that, navigate to the folder where you had saved the .ps1 file. Then copy the address of the folder location. Step 4: Next, change the directory by using the following command:

cd "folder location address"

Step 5: After that, enter the following script to disable the security questions:

Update-AllUsersQA

Once you’ve completed the steps above, the Security Questions should be disabled and you will be notified with a message stating that the feature has been disabled. On the other hand, if you have a change of heart and you want to enable the Security Questions back, here are some steps you need to take: Step 1: First, open the PowerShell window as admin. Step 2: Next, run the same script with one more parameter such as:

Update-AllUsersQA -answer SecretAnswer

Step 3: And that’s about it. Do not forget to replace the Secret Answer with your preferred one and once you’re done, it will be set as the answer for all the Security Questions. Step 4: Now all that’s left to do is go to the Settings app to change the answer to the questions and you should be good to go.

As you know, NVIDIA is one of the topmost graphics cards used and it has been that way for several years already. And in those years, the company has managed to release the best cards on the market. However, there are still times when some things fail and don’t work as expected due to some NVIDIA driver issues. As of late, one of the issues users reported about NVIDIA drivers is that it keeps on crashing on a daily basis. It gets to the point where they aren’t able to play games anymore while some users experience lag and rendering issues. In addition, some users also reported that their computer display tends to freeze sometimes, and then things would seem to go back to normal but only for a short span of time as the crash seems to happen every 10 minutes. This can be extremely annoying as you won’t be able to use your computer properly. If you are one of these users, worry not for there are several ways you can try to resolve the problem in your Windows 10 computer. Make sure to carefully follow the options given below.

Option 1 – Try checking if the NVIDIA graphics card is enabled

Although the problem is quite massive, the fix could be as simple as enabling the NVIDIA graphics card if it turns out to be disabled. There might be some strange reason why your graphics card disables itself. Thus, the best and first option you can try is to check if the NVIDIA graphics card is enabled or not. To do so, follow these steps:

• 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.
• After opening the Device Manager, look for the Nvidia graphics card option among the list of device drivers. Once you found it, check if it is enabled or not. If it’s not enabled, you should see a gray arrow pointing downwards. Right-click on the card and select Enabled.
• Next, right-click on the graphics card once more and click on the Update Driver Software option and then click on the “Search automatically for updated driver software” option.

Option 2 – Try to choose Maximum Performance and disable Vsync

If the first option didn’t work out for you, then you might want to try turning off Vsync and adjust the performance to the maximum. Refer to these steps to disable Vsync and adjust performance to the maximum.

• The first thing you have to do is right-click on your desktop and select the NVIDIA Control Panel among the options.
• After opening the NVIDIA Control Panel, select Manage 3D Settings.
• After that, set Vsync to off, and then in the Power Management Mode, set it to Maximum Performance. That should fix the problem.

Option 3 – Try updating the drivers from the official site of NVIDIA

If both the first and second given options didn’t work, you can also try updating the drivers from the official NVIDIA website. And in case you don’t know the type of Nvidia graphics card that your computer is on, follow the steps below:

• Tap the Win + R keys to open the Run dialog box.
• Next type in “dxdiag” in the field and click OK or hit Enter to open the DirectX Diagnostic Tool.
• From there, you can see what type of Nvidia graphics card that your system is on.
• Take note of your graphics card information and then look for the best drivers for your operating system. Once you’ve downloaded and installed the file, restart your PC.

Sticky Notes is one of the useful programs and in the early days, the option is available for users to change the font size of the text a lot easier. However, for some unknown reason, Microsoft decided to get rid of this feature in the latest Windows Update. One would expect that the feature will be replaced by an even more useful feature but it’s not which makes the Sticky Notes app worse than before. Worry not though for it doesn’t have to stay that way as there is another thing you can try to change the font size in your Sticky Notes app and that’s what we’re going to cover in this post. As mentioned, Microsoft removing this font feature is quite strange and in the past, users asked for this feature and since it’s no longer available, you can try following the steps given below to bring it back. And for that, you need to go to the Ease of Access section in the Settings app. Refer to the steps given below for more instructions. Step 1: First, tap the Win + I keys to open Settings and then go to the Ease of Access section. Step 2: After going to the Ease of Access menu and select Display from the list of options. Step 3: From there, you should see an option that says “Make text bigger”. And then use your mouse to navigate to the slider to change the size of the font. Note: Take note that after doing all the steps above, it will change not just the Sticky Notes app but also everything in Windows 10. This method is actually the best since it only changes the size of the apps rather than a wholesale change in your Windows 10 computer. Step 4: Next, scroll under Display until you see the “Change the size of apps and text on the main display” option where you’ll see that the option is 100% but you’ll want to change that to 125%. Step 5: After that, click on the drop-down menu and select 125% and then restart your Windows 10 computer. Step 6: Now open the Sticky Notes app and check if you can now change the font size in the Sticky Notes app.

So, you have finished with work, game, movie, music, email, or whatever on your PC, you look at the clock, it is late, you decide to go to sleep or outside, you click on the power button and choose shutdown. Now when a PC is shut down you feel good and go with your business but the next time you power it up you get the same error like the computer never really shut down in the first place. You wonder why and reboot it, just in case and all of the sudden error is gone.

If something similar has happened to you or you had the feeling that after shutting down your computer has not really felt like shutting it down, do not seek professional help, everything is OK with you because when you click on shut down, your computer does not really shut down!

Truth is that Microsoft has changed how to shut down works and how rebooting works in Windows with an update but has not publicly said anything about it so some users may experience this feeling of not shutdown phenomenon and might even think there is something wrong with their PC.

Why this change?

A few years ago shutdown button and option in Windows were really shutting down OS, but things changed when Microsoft wanted to increase boot-up speed. Now when that decision was made shutdown option was changed. So, what was changed? Well in order to increase Windows booting time, the shutdown will now turn off power to PC components and it will look like everything is indeed shutdown but the Windows kernel will actually be saved to a hard drive with all settings and just awaken once the PC is turned back ON. This will result in all errors and other stuff being just still present same as they were once the system was instructed to be turned off.

Rebooting your PC will now clear kernel and file from the hard drive and you will get a clean system startup without any issues tied with the kernel itself.

Workaround

Now that we know why and what change has been made to Windows logical question is can we shut down our PC at all properly? Luckily for us, the answer is yes and we will not need any external application to do it, we can still do it inside Windows itself and it is quite quick and easy.

Bringing back the old shutdown

In order to bring the old shutdown functionality of your PC please follow the instructions but be aware that by doing this your PC will boot a little bit slower since it will have to load the kernel from scratch each time computer is turned ON.

First thing is to go to settings and go to System

Then once you are inside the system, navigate to the power and sleep and click on it to select it. Once you have it selected to all the way to the right and click on additional power settings.

When you click on advanced power settings you should be led to the control panel's power options. Inside this panel click on top left link where it says Choose what the power button does.

Inside options, you will need to untick the box next to Turn on fast startup (recommended), this option has been ticked ON by the Windows update and probably without notifying you. Option means exactly what was described, it will save kernel state on the hard drive for faster boot time but sadly it can cause some issues since it will never be reloaded from 0.

If you are unable to uncheck the box click on the text beside the shield icon that says: Change settings that are currently unavailable (you will have to be logged in as administrator).

Conclusion

Altho turning off fast startup and shutting down the PC completely will for sure extend your bootup time I still believe that it is the right choice since sometimes a lot of clutter and bad things accumulate over time inside the OS and can cause a vast variety of problems in a long run. So stay safe and shut down that PC as it used to be in the past.

Great tips on protecting yourself from unwanted software

• When setting up anything on your computer system, always study the fine print, like the license agreement. Don’t accept terms of use that are for bundled programs. • Only Use the “custom” or “manual” install method – and never blindly click Next, Next, Next. • Use an advert blocker/pop-up blocker; Install anti-malware products such as Safebytes Anti-malware. These software programs could establish a wall between the computer and cybercriminals. • Think twice before you decide to download any type of freeware or shareware. Just before adding a plug-in or web browser extension, think about whether it is really necessary. • Only download programs from the original providers’ websites. Avoid download portals because they use their very own download manager to pack extra programs along with the initial download.
