The system found unauthorized changes

If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem.

When you encounter this kind of problem on your computer, you will get the following error message on your screen:

“Secure Boot Violation

The system found unauthorized changes on the firmware, operating system, or UEFI drivers.

Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed.

Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”

This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

  • First, boot your computer into Windows 10.
  • Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
  • After that, go to the BIOS of your computer.
  • Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
  • Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Select the UEFI Firmware Settings which will take you to the BIOS.
  • From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
  • Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
  • Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

  • Boot your computer into the Advanced Startup Options screen.
  • From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
  • Now select Troubleshoot > Advanced Options > Command Prompt.
  • After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

  • After making the bootable drive, you need to plug it into your computer and then reboot.
  • Next, tap the F10 or Esc key to open the boot options.
  • Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

Troubleshooting Fortnite Connection Issues
It is no secret that Fortnite is one of the most played games in the world. Epic has done a great job offering it to plenty of other platforms with cross-play feature meaning that you can play with your friends no matter on what platform they are on. But how Fortnite is a piece of software which is constantly updated and maintained it is pretty normal to have some bugs or issues from time to time. One of the before-mentioned issues is a connection issue or unable to connect to game servers. In our article, we will go through common fixes and solutions in order to get you back in-game as fast as possible. Keep on reading.

fortnite cannot connectCheck the Epic Games Status page

Check the Epic Games Server Status page to make sure all systems are operational. If the issue you’re experiencing is related to an outage or system-wide issue, you won’t be able to connect to the Epic Games Launcher or Fortnite until it's resolved.

Use a wired connection

Wireless connections are not as stable as wired connections. This means that the signal can be unreliable and result in packet loss, connection problems, or higher latency or ping. Connect directly to your modem or router with an Ethernet cable to eliminate this possibility and have the fastest connection possible.

Disable your firewalls

Often the quickest way to fix connection problems due to firewalls is to temporarily uninstall and/or disable it.

Windows Firewall disable guide:

  1. Click on Start.
  2. Click on Control Panel.
  3. Click on System and Security.
  4. Click on Windows Firewall.
  5. Click on Turn Windows Firewall on or off (You might need to provide the Administrator password at this step)
  6. Under each Network location, select the Turn off Windows Firewall option

Uninstall any other firewalls

Using a third-party firewall may prevent you from being able to connect to the Epic Games Launcher, Fortnite, or another Epic Games product. We recommend removing any third party firewalls temporarily to see if this resolves your issue. If it does resolve the problem, make sure to add the following executables as exceptions to your firewall:

Epic Games Launcher

  • C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64\EpicGamesLauncher.exe
  • C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win32\EpicGamesLauncher.exe

Fortnite

  • C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping.exe
  • C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_BE.exe
  • C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_EAC.exe
  • C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteLauncher.exe
Contact your firewall manufacturer for instructions on how to add these as exceptions to it as this varies between them.

Unblock your network ports

Network ports allow certain types of data to be successfully sent over a network that is used by our services. If you have any of these blocked, it may result in you being unable to connect to our games or use our services properly. To unblock your ports on your router do the following:

Windows

First, you will need to get your default gateway and internal IP address:

  1. Click on Start.
  2. Type cmd and press Enter.
  3. Type ipconfig and press Enter.
  4. Take note of your Default Gateway and IPv4.

Configuring your router to unblock the ports

Windows got stuck on Preparing Windows screen
You might have experienced a situation when you restarted your Windows 10 PC after an upgrade and you tried logging into your account but only a screen with a message saying, “Preparing Windows”. If the screen only stays that way, this indicates that Windows 10 is trying to complete the upgrade or waiting for some files to load up so that you can use your account. Some users also reported that when they tried logging into their accounts, they also get the same message on their screens. To resolve this issue, read on as this post will show you what you can do if your Windows 10 PC is stuck on the “Preparing Windows” screen. A lot of users have tried logging back into their account once more but to no avail as the same screen still greets them. And even when they tried the Ctrl + Alt + Del combo, it still didn’t work. This only goes to show that your account might somehow be corrupted.

Option 1 – Try booting your PC into Safe Mode

The first thing you can do to resolve the issue is to try booting your computer into Safe Mode and then log in using an Admin account. If it seems like your admin account has caused the problem, you need to create an admin account first and then log in after you reboot into the account and then log off. After that, restart your PC normally and check if the problem’s resolved or not. If not, refer to the next given option below.

Option 2 – Try to repair your corrupted profile via Registry

In this second option, you can try to repair the corrupted profile using the Registry but before you proceed, make sure to create a System Restore Point and then follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “regedit” in the field and hit Enter or click OK to open the Registry Editor.
  • Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
  • Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double-click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
  • You should know which among the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
  • After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
  • Exit the Registry Editor and restart your computer to apply the changes made.

Option 3 – Try running the System File Checker

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 your screen is stuck at “Preparing Windows”. 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
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 to repair hard disk errors using the Chkdsk utility

You can also run the Chkdsk utility to resolve the problem. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.
  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them.
  • chkntfs /t
  • chkntfs /t:10

Fix Windows Update Error Code 0x8e5e0147
As you already know, the Windows Update mechanism in Windows 10 is a bit complex as it depends on thousands of files and services in order to properly function. There are DLL files and services that support this mechanism’s proper functioning. And so if there is any malfunction with any of these files or services, it will result in some errors when running Windows Update. One of these errors is the error code 0x8e5e0147 which has the following error message: “There was a problem installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help – Error 0x8e5e0147” To fix this error, there are several methods you can try. You can run the Windows Update troubleshooter or reset the Windows Update components manually or clear the SoftwareDistribution folder and install the update manually. You could also reset the Windows Update Agent to default using a command in PowerShell.

Option 1 – Try to run the Windows Update troubleshooter

The first thing you can do to fix the Windows Update error code 0x8e5e0147 is to run the Windows Update Troubleshooter. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 2 – Try to reset the Windows Update components

If by any chance that the third option didn’t work, you can also try resetting the Windows Update components as it could also help you resolve the Windows Update error. How? Refer to the following steps:
  • Open Command Prompt with admin privileges.
  • After that, type each one of the following commands and hit Enter after you key in one after the other.
    • net stop wuauserv
    • net stop cryptsvc
    • net stop bits
    • net stop msiserver
Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS and MSI Installer.

    • net start wuauserv
    • net start cryptsvc
    • net start bits
    • net start msiserver
  • Close Command Prompt and reboot your PC.

Option 3 – Try downloading and installing the Windows Updates manually

Windows Update error code 0x8e5e0147 might be due to a Windows Update that has failed. So if it is not a feature update and only a cumulative update, you can download the Windows Update and install it manually. But first, you need to find out which update has failed, and to do so, refer to the following steps:
  • Go to Settings and from there go to Update and Security > View Update History.
  • Next, check which particular update has failed. Note that Updates that have failed to install will be displayed under the Status column which has a label of “Failed”.
  • After that, go to the Microsoft Download Center and look for that update using its KB number and once you find it, download and then install it manually.
Note: You can also use the Microsoft Update Catalog, a service from Microsoft that provides a list of software updates that can be distributed over a corporate network. With the help of this service, it can be easier for you to find Microsoft software updates, drivers as well as fixes. Option 4 – Try to reset the Windows Update Agent Since you can’t update the Windows Update Agent on your Windows 10 computer manually, you can try resetting it instead and you can do it using the Reset Windows Update Agent tool which you can download from the official Microsoft website.

GitHub introduction and explanation
If you are starting to get into the “wonderful” world of coding there is a high chance that you have heard of GitHub or Git for short and there is a slight chance that you might be confused about what exactly GitHub is. If this is the case, we are welcoming you to go through our article and find everything about it and why it is so popular and used all around the world.

githubWhat exactly is GitHub?

If we want to go all technical and just point the obvious we could say that GitHub is basically a WEB site and cloud service used for storing and managing code in all languages. But to truly understand why you should use GitHub and not Dropbox or any storage service instead you need to understand concepts like Version Control and Git.

Version Control

Version control is meant to help developers to work separately on different parts of codes and update is separately not breaking the original one. Take note that this option is meant when there is a big project and has more than one coder working on it. If you are a solo coder on your personal project this might not be anything groundbreaking for you personally. But let’s now assume that you are part of a team and that your task is to edit only one function of a project and other people working will also have their tasks. With version control, you could take only part of the code and work on it and once you are finished merge it back into the main repository. All changes in the main code are automatically tracked and can be easily reverted back if needed. The good stuff is that rolling back can be used only let’s say on a code you submitted and other changes made to the source can be kept. As you can see this makes a very good and efficient working space and a good coding environment.

Git

Git itself is a specific version control system, an open-source version control system to be more precise created by Linus Torvalds in 2005. It is a distributed version control system, which means that the entire codebase and history is available on every developer’s computer, which allows for easy branching and merging. Currently, over 87% of worldwide developers are using Git on a daily basis.

So GitHub is?

GitHub is a profit company that offers a cloud-based Git repository hosting service, in other words, it automates and makes it easy for everyone to use Git for version control and collaboration. It focuses on user interface and ease of use so even beginner coders can use it right away without any large confusion and using command lines and setting it themselves manually. GitHub also has a free personal plan in which you can host a public code repository completely free. This option placed GitHub very popular with open source projects. If you are a company you can purchase a plan to have a private code repository shared only to members of your team or company.

Conclusion

As stated almost every developer on a planet uses some version of Git, many of them are on GitHub and there is a lot of open source projects on it. Some employers even ask to see your GitHub repository when deciding if they want to employ you, think of it as a portfolio for coders. There is not a single disadvantage and not a single argument against using it, especially it has a personal free option. So if you want to look better and more professional in the coding world go, make an account and place some code on it, share it with the world, and see how it goes. You might even get some help on projects from other coders if you need it.

Cannot save media from Microsoft Photos
The Microsoft Photos app is a useful tool that allows users to view, edit, as well as create videos on their Windows 10 computers. Although it works just fine most of the time, there are some instances when you might encounter some issues when using it. One of these issues is when you cannot save media from the Photos app after you’ve edited an image. This is most likely related to a permission issue. However, according to some users, they got the error where the edited media file can’t be saved. When you encounter this kind of error, you will see the following error in your Photos app:
“It looks like you don’t have permission to save changes to this file. Try saving a copy instead.”
There are several options you can explore to resolve this error. You can try updating the Microsoft Photos app or verify the ownership of the destination folder. You can also re-register and reinstall the app. For more detailed instructions, make use of the options provided below.

Option 1 – Try to update the Microsoft Photos app

The first thing you can do to fix the problem is to update the Microsoft Photos app.
  • Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
  • Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 2 – Try to verify the ownership of the destination folder

The next thing you can do to fix the error is to verify the ownership of the folder because chances are, the location where you’re trying to save the file might not have enough permissions to read and write the file to the disk. Thus, you need to take ownership of the folder by following these steps:
  • Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
  • After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.
  • Next, type and enter this command: TAKEOWN /F <path>
  • Note that the <path> is the location of the folder or file in File Explorer.
  • Now type and enter this second command: ICACLS <path> /grant administrators:F
  • Finally, once the command has been executed, restart your computer and then see if you can now access the folder or file.

Option 3 – Try resetting the Photos app

If the first option of restarting the background process of the Photos app didn’t work for you, you can try to reset the Photos app so that it will use the default factory settings. Note that this option works when you are experiencing this issue after making a couple of changes in the Photos app.
  • To get started in resetting the Photos app, open the Windows 10 Settings.
  • Then go to Apps > Apps & features.
  • After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
  • From there, you will see the Reset button, click on it and click and then click on it once more to confirm.
Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 4 – Try reinstalling the Photos app

If none of the first two options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:
  • Open the Windows PowerShell program with admin privileges and key in the following command:
Set-ExecutionPolicy Unrestricted
  • After that, execute this second command to re-register and reinstall the Microsoft Photos app.
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

How to Fix CoreFoundation dll Error

CoreFoundation dll Error – What is it?

The CoreFoundation dll error is a common error associated with Apple Software products. Most of the Apple Software products rely on this dll file to load and run. This dll file is Apple’s proprietary. The error message is prompted in the following format:
“CoreFoundation.dll was not found” or “Apple Application Support is missing’.

Solution

Restoro box imageError Causes

The CoreFoundation.dll error message is triggered because of several reasons. These include:
  • Deleted CoreFoundation dll file
  • The CoreFoundation dll file has been overwritten
  • Poor installation of the Apple software
  • Corrupt software due to viral infection
  • Registry problems

Further Information and Manual Repair

It is advisable to fix CoreFoundation dll error code right away to avoid inconvenience. This error may stop you from accessing and running your desired Apple application. Here are some of the best ways to resolve this error on your system:

1. Restore the Deleted CoreFoundation dll File

Since Dynamic Link Library is a shared program, if you happen to delete an Apple program on your PC, chances are you might have deleted that file too in the process. Therefore, the easiest way to recover and restore the CoreFoundation dll file and resolve the error is to look for the file in the recycle bin. If you can’t locate it, then another way to restore the missing CoreFoundation dll file is to download the files from the internet.

2. Reinstall  Apple Software

If the error still persists then it is advisable to re-install Apple software via iTunes or any other Apple Software that you have on your PC. For example, if you have iTunes, then to reinstall it first go to the start menu and then the control panel. Now click on Add/Remove programs and locate iTunes software. Click the Uninstall button next to iTunes. Wait for a while until the program is completely uninstalled. After the installation is complete, restart your PC and then download the latest version on iTunes and install it. Now try running the software again. Hopefully, this will resolve the issue.

3. Scan for Viruses

Another way to resolve CoreFoundation dll error on your system is to scan for viruses. Run an antivirus to detect viruses and remove them from your PC.

Fix wdf01000.sys BSOD Error on Windows
If you encounter a Blue Screen error that points to the Wdf01000.sys file, then this post might be of help. Wdf01000.sys is a file related to the Windows Driver Framework which is the one that manages the system drivers. So if this file ends up being corrupted, the drivers would start to cause trouble in the system which would lead to a Blue Screen of Death error eventually. There are lots of error descriptions that are associated with the Wdf01000.sys file such as:
  • DRIVER_IRQL_NOT_LESS_OR_EQUAL
  • System_Thread_Exception_Not_Handled
  • Page_Fault_In_Nonpaged_Area
  • System_Service_Exception
  • Kmode_Exception_Not_Handled
  • DRIVER_VERIFIER_DETECTED_VIOLATION
Although the troubleshooting steps you must take depends on the kind of BSOD error you are getting, there are a couple of options you can try to resolve the Blue Screen errors related to the Wdf01000.sys file. Refer to the options given below.

Option 1 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
  • Open the Command Prompt with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • exe /Online /Cleanup-image /Restorehealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
  • Open the Devices Manager from the Win X Menu.
  • Then locate the device drivers and right-click on them to open the Properties.
  • After that, switch to the Driver tab and click on the Uninstall Device button.
  • Follow the screen option to completely uninstall it.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Use the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And so if you want to fix the Wdf01000.sys Blue Screen error, you need to use the Driver Verifier Manager:
  • Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
  • After that, select the option “Create custom settings”.
  • Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
  • Next, select the option “Select driver names from a list” option.
  • Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
  • Then click on the Finish button.
  • Open Command Prompt as administrator and execute this command – verifier /querysettings
  • The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
  • Open the Command Prompt as admin again and run this command – verifier /reset
  • The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 4 – Run the 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 to 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
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.
  • Reboot your computer.

Option 5 – Run the Blue Screen Troubleshooter

Reliability Monitor is not updating or working
In case you don’t know, there is a built-in tool in Windows 10, known as Reliability Monitor that provides a day-to-day snapshot of the health of your system. It warns users of any looming issues or disasters before your computer breaks down finally. So obviously, Reliability Monitor is useful, however, there are times when it could behave incorrectly. For instance, it might fail to show you any updates even when they are installed. Thus, if you experience any malfunctions with the Reliability Monitor tool in Windows 10, read on as this post will guide you in updating or working in Windows 10. To fix the problem with the Reliability Monitor, there are several fixes you can check out. You can try to enable the data collection for Reliability Monitor or reset it, as well as put your computer in a Clean Boot State. For more information, refer to each one of the options given below.

Option 1 – Try to enable the Data Collection for Reliability Monitor

The Reliability Monitor tool uses data provided by the RAC Agent scheduled task and it will start to display a Stability Index rating and specific event information 24 hours after the system installation. The RACAgent scheduled task, by default, runs after the operating system is installed. And if it is disabled, it must be manually enabled from the Task Scheduler snap-in for MMC or Microsoft Management Console. Thus, you need to enable the Data Collection for Reliability Monitor to fix the problem.

Option 2 – Try to reset the Reliability Monitor

The next thing you can do to fix the issue with the Reliability Monitor might want to reset it to resolve the problem. If the Reliability Monitor is already open, you have to close it and open it again. After the reset is done, it may take up to 24 hours for the Reliability Monitor to display results again. This should fix the problem.

Option 3 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. To identify which program is causing the problem, you need to put your computer in 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.)
  • From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Windows is unable to run Automatic Maintenance
As you know, Windows has a built-in Automatic Maintenance feature that takes care of important tasks such as security scanning and updating, Windows software updates, Disk Defragmentation, System Diagnostics, Disk Volume Errors, and many more. So if you receive an error message saying, “Windows is unable to run automatic maintenance, The maintenance schedule is unavailable”, then this post will guide you in what you can do to resolve this issue. Here are some suggestions you can try if the Automatic Maintenance in your Windows 10 PC is not able to run.

Option 1 – Enable Automatic Maintenance

It is possible that Automatic Maintenance has been disabled so you can try enabling Automatic Maintenance on your Windows 10 PC. To do so, follow these steps:
  • Go to Control Panel.
  • From there, select System and Security > Security and Maintenance > Automatic Maintenance.
  • After that, set the time you want to run the Automatic Maintenance and then check the checkbox saying, “Allow scheduled maintenance to wake up my computer at the scheduled time”.
  • Click OK to save the changes.
On the other hand, you can also enable Automatic Maintenance via the Registry Editor. But before you proceed, you need to create a System Restore Point first.
  • Tap the Win + R keys to open the Run dialog box.
  • After that, type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Navigate to the following path:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleMaintenance
  • Next, look for the “MaintenanceDisabled” key and then double click on it to open it and then set its value to “0”.
  • Click OK and exit the Registry Editor.
  • Restart your computer.

Option 2 – Check the Task Scheduler Services status

Majority of the tasks in Windows 10 run via services. So it is most likely that either the Service has been stopped or is set to the manual which is why Windows is unable to run Automatic Maintenance. Thus, you need to change it to automatic mode.
  • Tap the Win + R keys to open Run.
  • Type “services.msc” in the field and hit Enter to open Services.
  • Next, look for the Task Scheduler service and tap the T key on your keyboard which should take you to the services that start with T.
  • Double click on the Task Scheduler service and select the Automatic option under the Startup Type.
  • If it is not started yet, click on the Start button.
  • Then click Apply and OK to save the changes.

Option 3 – Check the Status in Task Scheduler

You can also try checking the status in the Task Scheduler. Just open the Task Scheduler > Task Scheduler Library > Microsoft > Windows > TaskScheduler. From there, make sure that Idle Maintenance, Maintenance Configurator, and Regular Maintenance are enabled.

Option 4 – Run the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Automatic Maintenance issue. 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 5 – Run the DISM tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:
  • Open the Command Prompt as admin.
  • Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
  • The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
  • Restart your PC.
