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:
Windows Resource Protection did not find any integrity violations.
Windows Resource Protection found corrupt files and successfully repaired them.
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.
Still sitting on the fence about upgrading to Windows 11 because you don’t know what to expect? Interestingly, the new edition somehow manages to be both a total revamp and still very similar to its predecessor in many ways. It’s really something to experience for yourself.
We do want to give you a sneak peek, though. So here’s an overview of the biggest changes Windows 11 brings to the table.
What’s different in Windows 11?
1. Visual changes
The first thing anyone will notice after switching to Windows 11 is the striking visual difference. The entire interface is smoother, cleaner and more minimalistic than on Windows 10, even resembling the macOS in some instances. Perhaps the most obvious change in appearance is the Start menu and Taskbar location, which is now at the bottom center. It’s actually very neat, but if you’re someone who loves familiarity, don’t worry, you can move it back to the left.
Centralized Taskbar and Start menu
Moreover, you’ll notice that the Taskbar includes a Microsoft Teams icon by default (which you can, of course, remove) and that Live Tiles are gone. The News and Interests section has also been removed - or, shall we say, replaced. As opposed to Windows 10, news, weather forecasts and other information are now displayed as widgets.
To add to the cleanliness of the UI, Microsoft also enhanced the ‘Snap Layouts’ feature to help you better organize your windows and maximize screen real estate. It’s similar to app grouping on your smartphone. In Windows 10 this feature is slightly restricted, as it requires some manual resizing and dragging. In Windows 11, you can just hover over the minimize/maximize option on a window, select a layout and throw the windows in there.

2. New accessibility features
Microsoft has certainly paid attention to accessibility with Windows 10, but Windows 11 takes this to a whole new level.
One of the ways Windows 11 has taken things up a notch is by adding the long-awaited ‘Live Captions’ feature and advanced Narrator options.
Live Captions apply both to media played on your PC as well as your own speech when you’re using the microphone. Keep in mind that, as with almost all kinds of subtitles, you have to be prepared for a potential delay. However, it’s barely noticeable and doesn’t take away from the usefulness of this awesome new feature whatsoever.
As for the Narrator, there are three new voice packs to choose from. Microsoft has tried to put emphasis on a more natural voice than we are used to. So, now you can choose between Aria, Jenny and Guy, who will read pretty much anything off your screen out loud. Aside from this, Microsoft has also expanded the list of braille displays supported by the Narrator feature. For users with anxiety or trouble concentrating, a welcomed addition is the Focus app, which is no longer part of the Clock app. It’s now separate and called ‘Focus Sessions’, automatically triggering the Do Not Disturb mode when activated. It blocks all pop-ups and flashes and lets you work in peace until you’re ready to switch it off.
3. Android apps
Android users may rejoice! Windows 11 supports the use of your favorite applications now.
Microsoft has done this by integrating the Amazon Appstore to the Windows 11 Microsoft Store. From there, you can download your favorite Android apps and use them on your PC in a smartphone-like window.
Unfortunately not too many apps are supported at this time, but Microsoft is working on making the emulation possible for many more. Also, the option is only available in specific regions at this moment - check out if you’re one of the lucky ones.
4. Improved gaming performance
Avid gamers will be happy to hear that Microsoft has put some effort into streamlining Windows 11 for their gaming needs.
To give gamers a supreme visual experience, Windows 11 offers the ‘Auto HDR’ feature. As long as your monitor is HDR-compatible, this feature will automatically adjust the colors, brightness and contrast of games without any input from you.
Another update is DirectStorage, which we were introduced to in Windows 10 already. In Windows 11, it’s been improved to tweak loading times and overall gaming performance efficiency even better. The predisposition for it to work optimally is that your device has an NVMe SSD.
The Xbox Game Bar also helps gamers towards a smoother experience. It allows in-game screenshots, viewing processes that are running (similar to the Task Manager), monitoring the CPU and GPU performance and frame rate, integrating the Xbox App and more. There’s also a number of widgets you can now use with the Game Bar, for example the Spotify widget.

Another cool addition is the Xbox Game Pass, which unlocks hundreds of games to play on your Xbox App, with new additions coming in every month.
5. Smart App Control
Aside from a sleek new look and better accessibility for all users, Windows 11 also comes with a security power-up. Bear in mind that this feature is only available on clean Windows 11 installs.
Smart App Control (SAC) is an AI-powered new feature designed to protect your PC from potential threats. It blocks untrustworthy apps and adware and helps detect potentially unwanted apps, maintaining your PC’s performance and keeping your system safe.
It comes with an ‘Evaluation’ mode, which you should definitely select when running SAC for the first time. That way, the app monitors your usage and assesses whether you’re a candidate for SAC. Some users need it to be on all the time, for others it might be too distracting. Evaluation mode will turn SAC on or off based on your usage.
Don’t disable SAC again unless you’re absolutely sure you don’t need it, since reenabling it will require a fresh install. We recommend you don’t turn it off, as it is a neat feature protecting your data and files from malware at all times.
