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.

Apple M2 Chip review

Direct replacement for Apple M1 Chip is near. There were some M1 Chips versions like M1 MAX and M1 ULTRA that were upgrades of the existing M1 chip, but the new and upcoming M2 is something different and it is aiming to replace M1 completely.

apple m2 chip

Made in a 5-nanometer design, with 20 billion transistors and 100GB/s of unified memory bandwidth is meant to increase performance over M1. It has the same M1 8 core design with 4 high-efficiency cores and 4 high-performance ones.

All CPU and GPU cores are faster than their M1 equivalents and Apple states that when running M1 and M2 at the same power level M2 will perform 25% faster. The first version of the chip will place focus on power efficiency so if you are more on side of being a power user wait for the MAX or ULTRA version of M2.

Tech details of M2

M2 system on a chip like its predecessor M1 combines both CPU and GPU on a single chip with shared memory in order to increase performance compared to systems that have separate CPU and GPU. M2 so far has been only announced for MacBook Air and the 13-inch MacBook Pro that suppose to hit the market somewhere around July this year. Of course, we expect that M2 is included in future iPad series or Mac Mini series as well.

  • CPU Cores: 8
  • GPU Cores: Up to 10
  • Unified Memory: Up to 24 GB
  • Neural Engine Cores: 16
  • Number of Transistors: 20 billion
  • Process: Second Generation 5nm

Fix fatal error C0000034 applying update
Fatal error C0000034 happens during the installation of the Windows update and if you are one of the unlucky users who sadly run into this, keep reading as we will provide solutions to this error and how to get around it. Start from point 1 to the bottom and hopefully you will have your PC back into working order in no time.
  1. Run Windows Update troubleshooter

    Usually, a built-in Windows troubleshooter can solve issues painlessly and fast, my advice is to try this as the first option, it is a simple and clean solution worth trying and in 90% it solves the issue all by itself.
  2. Do a clean boot

    Using task manager, remove all nonessential applications and services from starting up, reboot your computer, and once it is cleanly booted try re-running the update process again, if the issue was running the application this time everything will work since the problematic application is not running.
  3. Reset Windows update components to the default

    This solution requires you to use the Reset Windows Update Agent Tool to reset Windows Update components to default or use this PowerShell script to reset Windows Update Client. You can also manually reset each Windows Update component to default and then re-run the update.
  4. Disable firewall and antivirus

    Altho not likely it is still a possibility that some firewalls and antivirus can detect windows updates as malicious software and cut them off. If everything else failed, disable the firewall and your PC protection and when it is fully disabled try updating.
  5. Do automatic startup repair

    This should be the last thing to do but if everything else failed, do it. Perform Windows 10 Startup Repair. Once the startup repair completes successfully, you can re-run the update. The update should install without errors.

Fix Orange Screen of Death Error in Windows
The Windows 10 Orange Screen of Death, unlike Blue Screen of Errors, is quite an uncommon error where the hardware is the culprit which is mostly caused by some issues with the GPU. If you are currently facing this problem, then you’ve come to the right place as this post will guide you on what you can do to fix it. There have been reports from users that the Orange Screen of Death is caused by various reasons. Some users reported that they encountered Orange Screen of Death when they were watching a YouTube video, while some were not able to boot into their Windows 10 PCs and encountered an error instead of that either says, FAULTY_HARDWARE_CORRUPTED_PAGE or WHEA_UNCORRECTABLE_ERROR error. In addition, this error can also occur when your computer wakes up from Sleep or while using BitLocker, or while you use a second monitor. Whatever the case is, you can try updating your drivers or lower the clock speed of the GPU. You could also try to fix the DRIVER_IRQL issue in case it’s the one that triggers the error or performs Automatic Repair or uninstalls any recently installed software.

Option 1 – Update your Graphics card drivers

One of the possible reasons why you’re getting the Orange Screen of Death error is most likely related to the Graphics card drivers in your computer. Thus, the first thing you can do to resolve it is to update these drivers by following these steps:
  • 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.
  • After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
  • 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 2 – Try to uninstall software you’ve installed recently

If you have installed a software or two recently and then suddenly encounter this Orange Screen of Death, then they are most likely the culprits. The best thing you can do is to first check the System Log in the Event Viewer for any additional information in case it’s not the GPU but some other driver or device that’s causing the error. Once you have identified the culprits, uninstall them and see if the error is fixed.

Option 3 – Try disabling Overclocking

If overclocking is enabled, you might have to disable it as some users reported that the WHEA_UNCORRECTABLE_ERROR 0x00000124 error started to appear right after overclocking. To disable it, follow the steps below.
  • Go to the Start Menu and open Settings.
  • Next, select Update and Security and go to the Recover tab.
  • From there, click on Restart now in Advanced startup. This will restart your computer.
  • Once you’re in the Advanced startup, go to Troubleshoot and then select Advanced Options.
  • From there, select the UEFU Firmware Settings.
  • Now click on Restart. Once your computer has restarted, it will automatically open BIOS.
  • From the BIOS, go to the Advanced tab and navigate to Performance and then look for Overclocking.
  • Once you’ve found Overclocking, make sure that it is disabled. If it’s not, then disable it and then save the changes made by tapping the F10 key.
  • Start your computer normally and check if the WHEA_UNCORRECTABLE_ERROR 0x00000124 error is now fixed.

Option 4 – 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 5 – Try to run the Automatic Repair Utility

You might also want to use Automatic Repair in fixing the error. To do so, follow the steps below.
  • You can start by creating and booting from a bootable Windows 10 USB Stick.
  • After that, click on Repair your computer located on the bottom left corner when you are on the initial Windows Startup screen.
  • Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
  • Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

What to do when you can't format SD card
SD memory cards have surfaced as standard cards for digital cameras and microSD as phone standard memory cards. Most people have and use at least one daily, so naturally copying files and even formatting SD cards is a natural thing to do, but what if you cannot copy files or format SD cards? SD cardsFear not because we had this issue and tried several things in order to overcome the problem and after some time here is a list of what can you do if you are facing this exact issue. The list is written from most simple solutions to more complex ones and it is advisable to follow it as presented. That being said, let's dive into solving the problem.

1. Remove Write Protection on SD card

First and in my experience the most usual thing preventing deleting, copying files, and formating SD card is due to write protection. Take an SD card out of the laptop, camera, or card reader and visually inspect it. On side of almost every SD card, there is a hardware lock switch and mark where it needs to be positioned in order to be locked. Even if the switch is positioned on unlocked state, switch it to locked and then back to unlocked. Sometimes this easy moving of switch can resolve some contact issues and the card will start working normally. Another type of lock that could be turned ON is a software one. If for any kind of reason data protection has been turned ON, you will need to turn it off in order to be able to format an SD card. In order to do this follow this guide:
  1. Press ⊞ WINDOWS + R to open the Run dialog
  2. In run dialog type in diskpart and press ENTER
  3. Once diskpart is opened in command prompt type in: list disk and press ENTER
  4. Locate your SD card and type in select disk x, where x is disk number followed by ENTER
  5. After the SD card is selected type in: attributes disk clear read-only and press ENTER
This process will clear the software lock on the SD card, after following this method try to format the card again, if the problem still exists go to the next solution.

2. Format SD card using Command prompt

Command prompt is a great tool and can perform some commands that are not been able to be completed using file explorer or another tool inside Windows.
  1. In the taskbar search box, search for cmd and select the Command prompt
  2. On the right part select run as administrator
  3. If needed click on YES on UAC prompt
  4. Inside command prompt type in diskpart and press ENTER
  5. type in list disk followed by ENTER
  6. Select your SD card by locating its number in the list and typing select disk X, where is X SD cards number in list and press ENTER
  7. Once SD card is selected type in format fs=ntfs quick and press ENTER
This should format SD card but if for reason even this step is provided as unproductive, go to the next solution.

3. Format your card with the Disk Management tool

  1. Go into the taskbar and search for Disk Management and open it
  2. Select SD card partition that you wish to format
  3. Right-click on the partition and select format
  4. After the format is done, enter the volume label, file system, and allocation unit size. Confirm with OK
  5. Press OK again to confirm the formatting process.
If you have not managed to format your SD card even with this method go to the next solution.

4. Repartition card with Disk part

If all previous solutions have failed there is a chance that the SD card has bad sectors on it. If this is the case that we will need to partition cards in order to isolate bad sectors and use healthy ones.
  1. Press ⊞ WINDOWS + R to open the Run dialog
  2. In run dialog type in diskpart and press ENTER
  3. Once diskpart is opened in command prompt type in: list disk and press ENTER
  4. Locate your SD card and type in select disk x, where x is disk number followed by ENTER
  5. Type in Clean and press ENTER
  6. Type in Create partition primary and press ENTER
  7. To select a new partition type select partition 1 followed by ENTER
  8. Make partition active by typing active and pressing ENTER
  9. Format the drive by typing format fs=ntfs label=SDCard quick followed with ENTER
  10. Assign a letter to drive by typing assign letter=h followed with ENTER
  11. Type exit to close Command prompt followed again by ENTER and open File Explorer to check if the drive is active

5. Try a dedicated SD card formating fool

If anything failed so far, one last thing you could do is to download and try a dedicated SD card formatting tool. One that I would recommend is SD Memory Card Formatter, which is free software make specifically for formatting SD memory cards.

Fixing Upside Down Screen in Windows 10
As you know, Windows 10 comes with a pre-packed feature that allows you to rotate the screen at different angles, and to facilitate this feature, there are keyboard shortcuts you can use as well. However, from time to time, no matter how useful this feature is, users still experience a handful of issues. One of which is that they suddenly find their screen rotated or Upside Down even when they didn’t do a thing or adjust the setting. You may have pressed the shortcut on the keyboard by accident or some other program changed the setting on your computer without your permission – whichever the case is, this post will show you what you can do to fix the upside-down screen on your Windows 10 PC using the options laid out below.

Option 1 – Try using hotkeys

As mentioned earlier, Windows have hotkeys in the UI that changes the orientation of the display. So the first thing you need to do is to make sure that these hotkeys are enabled and if they are, you can use the keyboard shortcut to adjust the orientation of your screen.
  • Right-click on an empty part of your Desktop and then select the Graphic options.
  • Next, select “Hot Keys” > “Enable”. After verifying that the hotkeys are enabled, you can tap the Ctrl + Alt + Up arrow keys to change your computer screen’s orientation.
  • Alternatively, you can also tap the Ctrl + Alt + Right or Left or Down arrow keys to change the direction the other way.

Option 2 – Try using the Graphics Properties

You will probably see the “Graphics Properties” option if you use the Intel HD Graphics every time you click on your Desktop. Note that this option has all the graphics driver properties and helps you in changing the configurations as well as control several options like refresh rate, resolution, color-depth and many more. You have to navigate to these options to see if the orientation is changed in these properties. To do so, follow the steps below.
  • Right-click on any empty space on your Desktop and then select Graphics Properties or Intel Graphics Settings.
  • After that, select Display from the list of sub-options that appears.
  • From there, you will see the rotation of the screen under the “Display settings” option where you have to make sure that the slider is set to “0”.
  • Click the Apply button to save the changes made and then click on Exit. The orientation of your screen should automatically change.

Option 3 – Try using the Windows Display Settings

Since the Windows Settings have a section where you can manage the display settings of your computer, you can use them to help control the resolution of your PC’s display without any trouble. There is a possibility that the settings are changed there so that’s probably why your screen is turned upside down all of a sudden.
  • Tap the Win + S keys to open search and then type in “settings” in the field and then hit Enter to open Settings.
  • After opening Settings, click on System and then on Display using the left navigation bar and then scroll to the end and select the Advanced display settings.
  • Next, click on the Display adapter properties and click on Intel HD Graphics control panel.
  • Now change the rotation to 0 Degrees. Afterward, the display should revert back to its original form automatically.

Option 4 – Check your monitor’s physical controls

There are monitors that have buttons in them that allows users to shift the rotation of the screen to 90 degrees. It could be that your monitor has these buttons without you knowing and you suddenly pressed them by mistake which caused your screen to rotate. Thus, you have to check your monitor for any physical buttons on the side and if you see a menu, navigate to its options and check if there are screen rotation options. To make it easier for you, you can simply search your monitor’s model online and see if these buttons exist. You could also go over your monitor’s manual if you still have it as it contains details with regards to screen rotation.

Option 5 – Update your Graphics drivers

  • Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
  • Expand the section for the outdated device drivers.
  • And then select the outdated driver(s) and right-click on it/them.
  • From the drop-down menu, select the Update Driver option if you wish to update the driver or select the Uninstall device if you want to uninstall the driver and then follow the on-screen instructions to install the latest version of the driver.
  • Restart your PC after the installation to allow the system to reinstall the driver.

How to choose default applications in Windows
Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. Windows 10 Star menu with marked settings iconOn the settings screen, choose Apps. Windows settings apps section markedWhen the Apps screen opens on the left click on Default apps. Windows settings default apps markedOn right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.

Mobile Hotspot does not show up or detected
As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

  • First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
  • From there, click on the Edit button located under the Network name, Network password, and Network band.
  • After that, set the Network band to be at 2.4 GHz and then click on the Save button.
  • Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow these steps:
  • Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
  • Next, scroll down and select the “Network Adapter” option from the right pane.
  • Then click on the Run Troubleshooter” button.
  • After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: Follow the steps below to update your Network Adapter Driver:
  • Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
  • From there, expand the list of all the network drives and update each one of them.
  • Restart your PC and see if it helped in fixing the issue with the mobile hotspot.
Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.
