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.

CD/DVD icon is not showing in File Explorer
In the past, CDs, DVDs, and floppy drivers used to be the primary sources of external storage for many users – that is until the USB storage devices took over. These days, a lot of devices no longer have a built-in CD or DVD writer or reader as it contributes to the thickness of the device. On the other hand, there are still various devices that still come with a built-in CD or DVD writer or reader. However, recently, users who still use CD or DVD on their devices reported a problem where the CD or DVD icon is not visible in the File Explorer as well as in “This PC” or the My Computer page. The cause of this issue is still unknown at the time of writing, but there are still some potential fixes you can try to fix it. You can try to update or roll back the device drivers or apply some tweaks in the Registry Editor. For more details, refer to the given options below.

Option 1 – Try to update or rollback device drivers

The first thing you can try to fix the missing CD or DVD icon is 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. Note that the concerned drivers will be listed under the DVD/CD-ROM drives section as well as the IDE/ATAPI Controllers section.
  • From there, look for the following drivers:
    • ATA Channel 0.
    • ATA Channel 1.
    • Standard Dual Channel PCI IDE Controller.
  • Now, right-click on each one of the listed drivers and update them all. You could also try to roll them back to their previous versions.
Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try to use the Registry Editor

  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
  • Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E965-E325-11CE-BFC1-08002BE10318}
  • After that, look for the DWORD values named “UpperFilters” and “LowerFilters”.
  • Right-click on each one of these DWORD values and select Delete.
  • Now restart your computer and see if it fixes the problem.

Option 3 – Try creating a new Registry entry

There is another option you can try in the Windows Registry to fix the missing icon of the CD/DVD. You can try adding a new entry. How? Refer to these steps:
  • Tap the Win ­+ R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • After that, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesatapi
  • From there, right-click on “ATAPI” and select New > Key.
  • After that, name it is “Controller0” and right-click on the sub-key and then select New > DWORD (32-bit) Value.
  • Now name it as “EnumDevice1” and double click on it and then set its value data to “1”.
  • Click OK and restart your computer to apply the changes made successfully.

How to Remove PUP ExpressFiles Tutorial

ExpressFiles is a program developed by Express Solutions. A number of Anti-Virus programs have flagged this program as a Potentially Unwanted Application. In many instances, it is bundled with additional programs on installation.

The program claims it offers users easy to search for various currently popular search terms. During our testing, the software never displays any search results, no matter the search words. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times. The program defines an exception rule in Windows Firewall, allowing it to connect to the internet without limitations and auto-update itself.

About Browser Hijackers

Precisely what is a PUP?

If you’ve ever downloaded a free application or shareware, chances are high that the computer can get installed with a bunch of unwanted applications. A PUA / PUP (potentially unwanted application / potentially unwanted program) is a software program that comes bundled with free software and you consent to install it on your PC. These are programs you almost certainly don’t want on your computer simply because it doesn’t give any valuable service. Despite being regarded as very detrimental, PUPs aren’t always viruses or malware One simple difference between PUP and malware is distribution. Malware is normally dropped by silent installation vectors like drive-by downloads while PUP gets installed with the consent of the computer user, who purposefully or unknowingly approves the PUP installation on its PC. Having said that, there is no doubt that PUPs remain bad news for PC users as they can be incredibly damaging to the computer in numerous ways.

Exactly how do unwanted programs look like?

Potentially Unwanted Programs appear in different forms and varieties, however, in the majority of instances, they are adware programs that exhibit irritating pop-up ads and advertisements on websites you explore. In addition, the majority of free programs these days come with some unwanted add-ons; in most cases an internet browser toolbar or browser modification like a homepage hijacker. They’ll keep track of your online routines, redirect your search results to risky websites where viruses can be downloaded and installed, hijack your home page, and slow your browser down to a crawl. Potentially Unwanted Programs occasionally act quite much like computer viruses or spyware. They might carry keyloggers, dialers, browser hijackers, and tracking components that gather system details, or tracks customer habits and relays this information to third-party firms. Even if the PUPs really aren’t basically malicious, these software programs still do absolutely nothing good on your personal computer – they will take valuable system resources, slow down your PC, weaken your computer security, and make your system more susceptible to trojans.

How do you avoid PUPs?

• Read cautiously before accepting the license agreement as it may have a clause about PUPs. • Always opt for the custom if you’re presented an option between “Custom” and “Recommended” Installations – never click Next, Next, Next blindly. • Have a top-notch antivirus program like Safebytes Anti-Malware which can protect your computer from PUPs. As soon as you install this software, protection from malware and PUPs is already switched on. • Think carefully before you download any kind of shareware or freeware. Disable or get rid of toolbars and browser extensions you don’t really need. • Only use official product websites for downloading programs. Stay away from download portals altogether as most websites compel users to download the software using their own download manager, which is often bundled up with some sort of PUPs.

What To Do If You Cannot Install Any Anti-Malware?

All malware is bad, but certain types of malicious software do a lot more damage to your computer than others. Some malware types modify browser settings by adding a proxy server or modify the PC’s DNS settings. In these instances, you will be unable to visit some or all of the websites, and therefore not able to download or install the required security software to remove the infection. If you are reading this right now, you have perhaps recognized that a malware infection is a reason for your blocked web connectivity. So how to proceed when you want to install an anti-malware application like Safebytes? Follow the instructions below to eliminate malware by alternative methods.

Install in Safe Mode

The Windows-based PC comes with a special mode called “Safe Mode” where just the bare minimum required applications and services are loaded. If the malware is set to load immediately when the computer starts, shifting to this mode may well prevent it from doing so. In order to enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSConfig and locate the “Safe Boot” options under the “Boot” tab. As soon as you restart the PC into Safe Mode with Networking, you could download, install, and update anti-malware software from there. Right after installation, run the malware scanner to get rid of standard infections.

Utilize an alternate internet browser to download antivirus software

Web-based malware could be environment-specific, targeting a specific web browser or attacking particular versions of the web browser. If you’re not able to download the anti-virus application using Internet Explorer, this means the virus is targeting IE’s vulnerabilities. Here, you need to switch to a different web browser such as Chrome or Firefox to download the Safebytes Anti-malware program.

Install and run antivirus from a Thumb drive

Here’s yet another solution which is creating a portable USB anti-virus software that can scan your computer for malware without the need for installation. Try these simple actions to clean up your infected computer using portable anti-malware. 1) Download Safebytes Anti-Malware or Microsoft Windows Defender Offline onto a clean PC. 2) Mount the pen drive on the same PC. 3) Run the setup program by double-clicking the executable file of the downloaded software, which has a .exe file extension. 4) Select the drive letter of the USB drive as the location when the wizard asks you exactly where you would like to install the anti-malware. Follow activation instructions. 5) Now, insert the thumb drive into the corrupted PC. 6) Run the Safebytes Anti-malware directly from the pen drive by double-clicking the icon. 7) Click the “Scan” button to run a full computer scan and remove viruses automatically.

New focus sessions in Windows 11
focus sessionWindows and Devices chief Panos Panay has revealed new focus sessions feature that will be in Windows 11 on his Twitter account today. He himself is referring to it as a game-changer especially with Spotify integration.

So what is a focus session?

From the video clip provided on Twitter, we can see that focus session users will be able to choose a specific task from the previously made task list, choose songs that will play in the background while the task is active, and set a timer for the chosen task with breaks. Maybe the best comparison and explanation would be a desktop google calendar task with music, basically, that’s it. A neat and good organizer inside your Windows 11 operating system. I think that this is generally a good idea and for sure it will find its audience.

MS Edge, autoplay video blocking coming
Microsoft Edge may be about to win a lot of fans by introducing a new feature that it says could prevent one of the most annoying things about being online. A new update to the browser suggests it is looking at a way to block auto-playing videos by default when a user navigates to a website. People spotted a new entry to the Microsoft Edge Canary browser where the company tries out its in-progress updates, that suggests auto-playing videos may have had their day at last. The new addition, for Mac, Windows, and Linux systems, is called “Autoplay Limit Default Setting”, with the description suggesting that Microsoft Edge would set the media autoplay setting to "Limit" as a default - stopping videos from starting up when a user lands on a website. Currently, Edge offers two options for users to control media autoplay - "Allow" (the current default setting), where all videos on a website will play automatically with sound, and "Limit", where media won’t be autoplayed on sites that a user has previously visited. It appears that Microsoft is looking to test the feature in Canary before rolling it out to a wider user base - as blocking autoplaying videos can cause issues for some websites. The same Canary entry also hints at a future "Block" option, which would presumably stop any videos or media from playing when a user lands on a website. However, this feature, which is also listed as being available for Mac, Windows, and Linux systems, doesn't appear to be enabled as yet.

How to turn off Live Photo on iPhone

Apple introduced the Live Photo feature way with iPhone 6S in their iOS9. Live Photo idea was that each time you take a photo, your phone will capture a few seconds of video along with sound and all of that is sent when you share your photo. This of course can sometimes be really bad when some not wanted audio gets recorded in the background.

live photo

Since the feature was introduced it has been set as the default option when taking pictures so each time you snap one you just capture a small amount of video and audio along. Good thing is that this feature can be turned off and the even better news is that you can edit your old photos to remove back video and audio.

How to share only photo

You can keep your Live Photos but share only a single still typical photo if you wish. Go to the photos app on your phone and select the photo you wish to share. Press the Share button on the bottom left part of the screen and once the Share menu appears tap on the Live button in the upper left corner of the selected photo. The button should turn grey and become slashed and now you can share only still photo. This is only temporary for this one specific share so next time you want to do this you will have to go through the process again.

How to disable Live Photo

If you are not happy with the previous solution and really do not want to turn off the Live feature each time you want to share a photo or you just simply do not want the feature at all there is way to turn if off for good. Take note that you can temporarily not use this feature just by opening the camera, switching to photo mode, and then tapping on the Live photo button on the toolbar that looks like three circles one inside another. This will temporarily turn the Live Photo feature for this session but next time when you open the camera by default it will be turned on again. This is a good approach if you want the feature but sometimes you just want not to use it.

In order to turn it off completely go to the settings of your phone and go to Camera and then preserve settings. inside the preserve setting turn the switch Live Photo to ON position, now go-to camera and again click on the live photo button to turn it off but this time setting will be saved and next time you open the camera it will not be ON.

Editing old Live Photos

As stated before you can edit your old pictures in order to make them stills. You can edit them to remove audio only but keep the video part, or you can completely remove everything and convert them into typical still images.

In order to only remove audio from your Live Photos go to pictures and select one that you wish to change, click on edit, and inside edit tap on the Live Photo icon (three circles). Next tap on the audio icon located in the top left corner of your screen and it will change into the mute icon. Click on done and you are finished.

To completely remove the Live photo go to Photos, select picture, click on edit and select the live photo button again. This time tap and hold the Live button next to the sound until it turns gray with a strike through it. Click on done and you are finished.

Find out bottlenecks in your PC easily
Building a custom PC is a great feeling but it can sometimes not be ideal and we are not talking about breaking or losing parts. What we mean is that choosing the right components can be sometimes a difficult task. Of course, picking a PC case can have its issues, choosing the right power supply can be tricky but pairing all components together, especially CPU and GPU can be tricky. bottlenecksBuilders with no depth knowledge and experience can sometimes choose improper CPU or GPU, picking one of them to be much more powerful than another thus not using it to its full potential because another component cannot handle stuff at the same speed. In order to not be trumped by this kind of stuff, there is a website that is completely free and you do not even need to be registered in order to use it. Bottlenet calculator link here What is even better, once you input your components you will get advice on what to change in order to tweak the system a little more to avoid bottlenecks even more. It is a very useful tool and we are advising you to use it in order to save money but not throwing it on some component that will be half used.
