How to Fix Unknown Hard Error in Windows 10

The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work.

Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error

In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC. Ctfmom is a process that identifies inputs such as handwriting, languages, and many more. It’s the one that controls the functions of background behavior. To resolve this issue, you need to first try to identify which application is the one that’s running the sihost.exe file. And if needed, you need to either update or reinstall or completely uninstall the problematic application.

Option 1 – Try to run the System File Checker

The SFC Scan or System File Checker, us a built-in utility in Microsoft Windows that can be found in the C:\Windows\System32 folder. This tool allows users to scan and restore any corrupted system files in Windows that might be causing the Unknown Hard error to appear. Before you use this tool, make sure to find out whether the sihost.exe on your computer is a Trojan that you have to remove or if it’s a file that belongs to a trusted Windows application. Once you have that sorted out, follow the steps 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 2 – Try to use System Restore

You can also try using System Restore. This is one of the ways you can use it to back up your PC. Since restore points are created automatically each week by System Restore, you can use System Restore to restore your computer back to an earlier good point in time.

Option 3 – Try to troubleshoot the error in a Clean Boot State

Putting your PC in a Clean Boot state can help you diagnose and troubleshoot the issues in your system. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the Unknown Hard Error.

  • 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 putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

  • From the “Start” menu, go to System Configuration.
  • After that, switch to the General tab and click the option for “Normal Startup”.
  • Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
  • Then find and click “Enable all” and if prompted, you have to confirm.
  • Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
  • Restart your PC when prompted.

How to remove AudioToAudio (Browser Extension) from your PC

AudioToAudio is a browser extension for Google Chrome developed by Mindspark Inc. This extension allows users easy access to popular audio converting websites.

When installed, it changes the default search engine, home page, and new tab to MyWay.com. While active AudioToAudio gathers user browsing activities such as, but not limited to: visited websites, clicked links, search queries. This data is later used/sold by the Mindspark ad network to better target ads. While browsing the internet with this extension enabled, you will see additional injected ads, sponsored content (such as links to web pages, banner ads, affiliate shop links, etc), and even pop-up ads from time to time if the regular ads are blocked. AudioToAudio has been marked as a Browser Hijacker by several anti-virus applications and is marked for removal by most of them.

About Browser Hijackers

Browser hijacking is a form of unwanted software, commonly a web browser add-on or extension, which causes modifications in web browser’s settings. They are created to interfere with browser functions for various purposes. Typically, hijackers are developed for the benefit of cyber hackers often through revenue generation from forced ad clicks and website visits. However, it isn’t that innocent. Your online safety is compromised and it is also extremely annoying. Some browser hijackers are programmed to make particular modifications beyond the browsers, like changing entries in the computer registry and letting other malware further damage your computer.

How to determine if your browser has been hijacked

When your web browser is hijacked, the following might happen: 1. your web browser’s homepage is suddenly different 2. you get re-directed to sites you never meant to visit 3. The default search page of the web browser is changed 4. discover new toolbars that you simply did not add 5. you see numerous ads pop up on the web browsers or computer screen 6. webpages load slowly and often incomplete 7. Inability to navigate to certain websites, especially antivirus and also other computer security software sites.

How they infect computers

There are many ways your computer or laptop can become infected with a browser hijacker. They usually arrive by way of spam email, via file-sharing networks, or by a drive-by-download. They can also be deployed via the installation of an internet browser toolbar, extension, or add-on. A browser hijacker could also come bundled up with some free software that you unknowingly download and install the browser hijack, compromising your PC security. Some of the most well-known hijackers are AudioToAudio, Babylon Toolbar, Conduit Search, OneWebSearch, Sweet Page, and CoolWebSearch.

Removing browser hijackers

Some hijackers could be removed by just uninstalling the related freeware or add-ons through the Add or Remove Programs in the Microsoft Windows Control Panel. But, the majority of hijackers are quite tenacious and require specialized applications to eliminate them. Novice computer users shouldn’t ever attempt the manual form of removal, as it requires thorough computer knowledge to carry out repairs on the computer registry and HOSTS file. Browser hijackers can be effectively removed by installing and running anti-malware software on the affected PC. Safebytes Anti-Malware has a sophisticated anti-malware engine to help you prevent browser hijacking in the first place, and mop up any existing issues. In addition to anti-malware, a system optimizer tool, similar to Total System Care, could help you resolve Windows registry errors, eliminate unwanted toolbars, secure online privacy, and increase overall computer performance.

Windows Search not searching the entire PC
There are times when the Windows Search results do not include what you want to search. However, if you are trying to search for something that’s located on your desktop and Libraries, they would appear right away on the search results. Actually, the issue is not with the search but with the list of files and folders that Windows can index. If you encounter this issue, read on as this post will guide you on how to fix it. The Windows 10 operating system, ever since Windows v1903 was released, offers two kinds of searches – the classic and the enhanced search. You may have to add more folders to the classic search or use the enhanced mode to resolve the issue. In other words, to fix the problem with the Start Menu Search, you can try to enable the Enhanced Mode or add folders to the Class Search or remove the excluded folders, as well as run the Search and Indexing troubleshooter. For more information, refer to each one of the options provided below.

Option 1 – Try to enable the Enhanced Mode

To fix the problem, you have to enable the Enhanced Mode search and configure the folders you want to be indexed. How? Follow these steps:
  • First, you have to go to Settings > Search > Searching Windows.
  • Next, select the radio button for the Enhanced option.
  • After that, select the folders you want the Windows Indexer to exclude from the Enhanced Search mode.

Option 2 – Try to add folders to the Class Search

If you don’t want to enable the Enhanced search mode, then you might want to add folders that are important to you. All you have to do is configure the Search Indexing Options by following these steps:
  • Go to Settings > Search > Classic and from there, click on the “Customize search locations” option.
  • Next, click on Modify in the pop-up window that appears.
  • Then add drives and folders that are important to you. Once the indexing is completed, Windows will be able to find the file and display it in the search results.

Option 3 – Try removing the excluded folders

If you have already enabled the Enhanced mode but your files still don’t appear, then you might want to check out the excluded folder list.
  • The first thing you have to do is go to Search and from there, you will find a list of folders under the Excluded folder list.
  • Next, click on the excluded folder that you want to remove by clicking on the “Remove Excluded folders” button.
  • If you are using the Classic search, you have to check if the index has restrictions on the file type. You can find it in Advanced options > File Types.
Note: If you want to search in Documents, you could also enable the Index Properties and File Contents. This should resolve the problem.

Option 4 – Try to run the Search and Indexing troubleshooter

You might also want to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for the Windows Start Search are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter.

To perform System Restore, refer to these steps:
  • First, press 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.
If the problem wasn’t fixed and you’re still getting false notifications, you might want to troubleshoot the problem further using the options given below.

Option 1 – via Windows PowerShell

  • In the Start search, type “PowerShell” in the field and hit Enter to pull up the Windows PowerShell window.
  • Next, copy and paste this command and hit Enter to execute it: Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppxManifest.xml” -verbose }
  • After that, reboot your computer and check if the false notifications are now gone.

Option 2 – Try renaming the Usrclass.dat file

How to Fix Error Code 0xC004F00F on Your PC

Error Code 0xC004F00F – What is It?

Error Code 0xC004F00F can appear during the Windows 10 installation and activation process. It is a fairly straightforward error code that occurs when a product key is entered in that is unable to be used to complete the final activation of the new operating system. This error code is most commonly related to the installation of new pieces of hardware on a machine that was already running Windows 10 at a previous time.

Error Code 0xC004F00F can also appear on other versions of the Windows software, so if you are not specifically trying to install and activate Windows 10 when this message appears, you may want to contact a qualified Windows technician to help resolve your system error, as the error code has different causes and resolution methods on other versions of the Windows operating system.

Solution

Restoro box imageError Causes

In some cases, Error Code 0xC004F00F will show up if you are attempting to install Windows 10 on a computer in which the hard drive has been replaced or significantly altered. It can also appear when other major pieces of hardware, like the motherboard, have been changed out.  These pieces may be changed as part of an upgrade to new or better hardware or be changed due to the malfunction of the original pieces of equipment. Because it may appear to the Windows activation servers that you are attempting to use the same product code that you have used before to activate what appears to be a new machine (even if the machine is the same one, just with some new parts), you may see Error Code 0xC004F00F arise.

Error Code 0xC004F00F can also come up if you have installed Windows 10 on your machine in the past and have already used the product key that you are attempting to use again.

Further Information and Manual Repair

Error Code 0xC004F00F most commonly appears for users who have made major hardware or software changes done on their machine. Because this error specifically arises from the Windows activation servers believing that your computer is a new one, you’ll need to get in touch with the Windows support team in order to resolve the error. From their database, they will be able to confirm that you are not using a new computer and will be able to bypass the error, allowing you to complete the Windows 10 Activation process.

If you haven’t installed or replaced any of the hardware on the computer, but are still seeing Error Code 0xC004F00F arise during your Windows 10 installation, you will still need to get in touch with the Windows support team to bypass the error code.

Calling the Windows' Support Team

When you call into the Windows support team, you’ll want to specifically have a list of the following information readily available: Which pieces of hardware have been changed out on your computer prior to the installation and activation, what method you were using to install Windows 10, which version of Windows 10 that you were attempting to install, whether it was a single-use or multiple-use license, and basic details about your PC like its make, model, and age.  You may also want to have the product key that you were attempting to use when Error Code 0xC004F00F first appeared.

By having all of this information ready and on hand ahead of time, you’ll have a greater likelihood that your error will be able to be resolved quickly and efficiently, avoiding long periods spent on the phone with customer service. Make sure that you specifically mention that you are experiencing Error Code 0xC004F00F during the Windows 10 activation process when you call into the Windows support team so that you can be connected to a representative who is equipped to help you resolve this specific problem.

Getting a Qualified Technician

If you are not comfortable in working with the Windows support team or have not been able to successfully resolve Error Code 0xC004F00F even after getting in touch with customer support, contact a qualified technician who is familiar with the Windows 10 activation process and can walk you through the things that you will need to communicate to the Windows support team in order to have them bypass or resolve the error code.

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

What is HEIF file format and how to use it?
High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items
Storage of individual images, image properties, and thumbnails.
Image derivations
Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.
Image sequences
Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.
Auxiliary image items
Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.
Image metadata
Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.

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.

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

  1. Open your web browser.
  2. Type your Default Gateway into the address bar and press Enter. (A common Default Gateway is 192.168.1.1)
  3. You may be asked for a username and password. This varies for each router. Before entering anything, try just hitting OK. If that doesn't work, try the common default username and password below: Username: admin Password: password If these don't work, you can check this website for a list of usernames and passwords based on your router model.
  4. Locate the Port Forwarding page in the administration tool and click on it.
  5. Make sure you have Port Forwarding selected and not Port Triggering as this is completely different.
  6. On this screen, you will need to enter the ports and port ranges below with the correct protocol and local IP of which you took note of above: 80 (TCP/UDP), 433 (TCP), 443 (TCP), 3478 (TCP/UDP), 3479 (TCP/UDP), 5060 (TCP/UDP), 5062 (TCP/UDP), 5222 (TCP), 6250 (TCP/UDP), and12000-65000 (TCP/UDP).
