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.

Windows uses 2 types of keys for its activation, KMS or MAK. These keys should work without any issues since they are elevated with higher permissions but in some cases, they are by accident run without their proper permission, and then we have access denied error or error 0x80070005 To resolve this issue please first check if not by any chance your antivirus or firewall is preventing slmgr.bs file to access the right permissions, that being said if the previous solution is not working note that you have to be an administrator of the system or have administrator privileges. As an administrator, you will have to use Software Licencing Management Tool or short SLMGR.VBS, a VBS file in Windows used for its activation purposes. As an administrator, open Command prompt with admin permissions and then run slmgr.vbs This will make sure that activation goes through, make sure to use proper options like:

/ipk <ProductKey> or /ato [<Activation ID>]

About Browser Hijackers

Browser hijackers (sometimes known as hijackware) are a kind of malicious software that alters web browser settings without the computer owner’s knowledge or consent. These types of hijacks are increasing at an alarming rate around the globe, and it could be really nefarious and often dangerous too. They’re created to disrupt browser programs for various purposes. In most cases, hijackers are designed for the benefit of online hackers usually through income generation from forced advert mouse clicks and site visits. Though it might seem naive, all browser hijackers are damaging and thus always regarded as security risks. In a much worst case, your browser could be hi-jacked to download malware that will do a great deal of damage to your computer or laptop. Major symptoms that an internet browser has been hijacked Signs that an internet browser is hijacked include: 1. home page is changed 2. bookmark and the new tab are also modified 3. the essential web browser settings are modified and unwanted or insecure sites are put into the trusted websites list 4. discover new toolbars that you didn’t add 5. never-ending pop-up ads appear and/or your web browser popup blocker is disabled 6. your web browser has become unstable or starts running sluggishly 7. you’re disallowed access to specific web pages, for example, the website of an antivirus software manufacturer like SafeBytes.

Precisely how browser hijacker infects computers

A browser hijacker can be installed on your computer if you visit an infected website, click an email attachment, or download something from a file-sharing site. They are usually included with toolbars, add-ons, BHO, plug-ins or browser extensions. Other times you may have accidentally accepted a browser hijacker as part of a software program bundle (usually freeware or shareware). An example of some well-known browser hijacker includes Anyprotect, Conduit, Babylon, SweetPage, DefaultTab, RocketTab, and Delta Search, but the names are regularly changing. The existence of any browser hijacker on your computer can substantially diminish the web browsing experience, record your internet activities that result in troublesome privacy issues, create system stability problems and finally cause your computer to slow down or to a practically unusable state.

Browser Hijacker Malware – Removal

Some hijackers can be removed by uninstalling the freeware they were included with or by removing any extension you have recently added to your system. However, most browser hijackers are hard to get rid of manually. No matter how much you try to eliminate it, it might come back over and over. You should think about performing manual repairs only if you are a tech-savvy individual, as there are potential risks associated with messing around with the system registry and HOSTS file. Installing and running antivirus application on the affected computer could automatically erase browser hijackers and other malicious programs. SafeBytes Anti-Malware discovers all kinds of hijackers – including PriceGong – and eliminates every trace quickly and efficiently. Use a system optimizer along with your antivirus software to solve various computer registry issues, remove system vulnerabilities, and improve your computer's overall performance.

Device drivers are needed in order for the hardware and software to communicate in an operating system. Some of these drivers are digitally signed. These kinds of drivers are drivers that are signed by their issuing authority in a way that the end-user or any third party won’t be able to modify them. And there are times when you encounter an error that says, “Windows requires a digitally signed driver” when you try to install or update device drivers. Driver Signing is the process of associating a digital signature with a driver package. Digital signatures are used in Windows device installations to verify the identity of the vendor providing the driver packages as well as to verify the integrity of the driver packages. All the drivers you usually install on your PC from Windows Update, Original Equipment Manufacturers, or some other third-party driver download software and so on must be verified digitally by Microsoft through the digital signature. A digital signature is an electronic security mark that verifies the publisher for the driver and all the relevant information related to it. That’s why Windows won’t run a driver if it isn’t certified by Microsoft, be it a 32-bit or 64-bit system – this is called the Driver Signature Enforcement. The only Kernel-mode drivers that Windows 10 will load are the ones that are digitally signed by the Dev Portal. However, the changes only affect the new installations of the operating system with Secure Boot on while the non-upgraded fresh installations would require drivers that are signed by Microsoft. The “Windows requires a digitally signed driver” error indicates that the driver you are trying to update or install hasn’t been signed digitally by the issuing authority, preventing you from installing or updating it. To resolve this issue, you can try to update the drivers directly from the manufacturer’s site. You could also disable driver signing via Group Policy Editor.

Option 1 – Update the device drivers directly from the manufacturer’s site

The reason why you’re getting the “Windows requires a digitally signed driver” error in the first place is that you might have downloaded the drivers from external media. It could also be that the drivers didn’t update for some time now and the issuing authority changed its policies. Thus, you can try to update the drivers straight from the manufacturer’s website and install them. If this option didn’t work, then you’ll have to disable the driver signing or its recognition in Windows 10. Keep in mind that doing so is not advisable if you have to use the concerned driver.

Option 2 – Disable driver signing via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: User configuration > Administrative templates > System > Driver installation
• Next, double click on the “Code signing for device drivers” entry located on the right pane to open its properties where you’ll see the following description:

“This setting determines how the system responds when a user tries to install device driver files that are not digitally signed. It establishes the least secure response permitted on the systems of users in the group. Users can use the System in Control Panel to select a more secure setting, but when this setting is enabled, the system does not implement any setting less secure than the one the setting established. When you enable this setting, use the drop-down box to specify the desired response. “Ignore” directs the system to proceed with the installation even if it includes unsigned files. “Warn” notifies the user that files are not digitally signed and lets the user decide whether to stop or to proceed with the installation and whether to permit unsigned files to be installed. “Warn” is the default. “Block” directs the system to refuse to install unsigned files. As a result, the installation stops, and none of the files in the driver package are installed. To change driver file security without specifying a setting, use System in Control Panel. Right-click My Computer, click Properties, click the Hardware tab, and then click the Driver Signing button.”

• Now select the radio button for “Enabled” and select Ignore from the drop-down menu under “When Windows detects a driver file without a digital signature”.
• Then click on the Apply and OK buttons to save the changes made. This will get rid of the “Windows requires a digitally signed driver” error but take note that this will also make your system less secure.

As you know, the Windows 10 operating system has support for a dedicated high-end graphics processor that brings in capabilities inside to support Graphics Cards from NVIDIA or AMD. This helps the operating system to function in a much better way by segregating the graphics-intensive operations from the CPU to a dedicated processor. However, there are times when it also experiences some issues that lead to some errors like the “Failed to create a graphics device” error. It is possible that your computer has more than one screen or graphics card which is why you’re getting this error. To fix it, you need to try reinstalling DirectX or reinstall the Graphics Card driver. You could also try to manually check the hardware or power cycle of your computer. To start troubleshooting the “Failed to create a graphics device” error, follow the given suggestions below.

Option 1 – Try running the DirectX Diagnostic Tool

Since the error has something to do with the DirectX Graphics APIs, you can run the DirectX Diagnostic tool to resolve the problem.

Option 2 – Try updating or re-installing DirectX

If the DirectX Diagnostic tool didn’t work, you can try to update or reinstall DirectX instead. This can help in fixing the problem because when you reinstall or update DirectX, it will replace the incompatible or corrupted components of DirectX from your computer.

Option 3 – Update or reinstall the Graphics card drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in MSC into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.

• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 4 – Try to physically check the hardware of your computer

You might also want to check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Graphics Card of the computer. In doing so, you have to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.

Option 5 – Try to power cycle your computer

You could also try to power cycle your computer to fix the error. To do that, you have to turn off your computer in a way that the power is completely cut off and all the fresh configurations of files are loaded when your computer is booted up. The first thing you have to do is to shut down your computer and if you are using a laptop with a removable battery, you must remove the battery for a couple of minutes before you plug it back in and boot your laptop. On the other hand, if you are using a desktop computer, press and hold the power button until the CPU goes off and take out the power cable for a minute or so and then plug it back in. Boot your computer and see if the error has been resolved.

Recently, a number of Windows 10 users getting an error on their computers that state, “Windows can’t find one of the files in this theme”. According to the affected users, this error occurs at random times even when they didn’t make any changes to their computer’s theme prior to getting the error. If you are one of these users, read on as this post will help you resolve this problem. If you click on the Yes button of the dialog box where the error is displayed, it won’t fix the problem as you will still get the same error from time to time. This kind of error could be caused by the executable file named “SettingSyncHost.exe”. It is possible that this executable file is unable to sync your theme all over your computer. On the other hand, it could also be due to some problems with the active theme. To resolve this issue, you can try to change the active theme, or disable the custom screensaver or disable theme syncing on your computer, as well as run a System File Checker or run the DISM tool. For more instructions, follow the options given below.

Option 1 – Try to change the active theme

The first thing you can do to fix the error is to change the active theme of your computer since the SettingSyncHost.exe file might not be able to properly sync the theme on the computer.

• Go to Settings and click on Personalization.
• Next, click on Themes and scroll down to apply a theme, and change the theme of the operating system.
• After that, tap the Win + R keys to open the Run dialog box and type “%windir%ResourcesThemes” in the field, and then tap Enter to open the folder where the theme files are located.
• Once you’re done, right-click and select delete for the active theme to remove the theme and its resources. This should fix the root cause of the problem. If not you can try to create a new Windows 10 theme and save it.

Option 2 – Try to disable the custom screensaver

The custom screensaver is a part of the mechanism of the lock screen. Although they were needed in the earlier Windows versions to prevent the discoloration of CRT monitor screens, they are no longer needed in the current version of Windows. Thus, you can try to disable it as it could be the one that’s causing the problem.

• Click on the Start button and go to Settings > Personalization > Lock screen.
• Here, scroll down and click on the Screen Saver settings.
• After that, select the “Screen saver to (None)” option from the drop-down menu. This will disable the custom screensaver.

Option 3 – Try to disable theme syncing on your computer

You could also try to disable the theme sync feature to fix the problem. This has worked out for some users. To do so, follow these steps:

• Click on the Start button and go to Settings > Account > Sync your settings.
• From there, toggle off Themes in the individual sync settings column. This will disable the Theme syncing.
• Restart your computer and see if the problem is now fixed.

Option 4 – Run the DISM tool

The next thing you can do is run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the “Windows can’t find one of the files in this theme” error. To repair these corrupted system files, you can run the DISM commands:

• 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
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer and check if the problem is now fixed.

Option 5 – Run 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 to good system files that might be the cause why you’re getting the “Windows can’t find one of the files in this theme” error. To run the SFC command, follow the steps given below.

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

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

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