How to Repair Windows 10 Upgrade Error 0x800F0923

If you are typing inside the Search bar, Cortana, Taskbar, Windows 10 apps, etc., and then everything seems invisible then read on as this post will guide you in fixing this issue. At first, you might think that something is wrong with your keyboard but it really has nothing to do with it. The problem actually lies with the apps from Microsoft Store. Thus, if you can’t type anything in any of the apps from Microsoft Store in Windows 10, refer to the options given below to fix them.

Option 1 – Ensure that ctfmon.exe is running

Ctfmon.exe is a Microsoft process in Windows 10 that controls the Alternative User Input as well as the Office Language bar. In other words, it enables end-users to control the computer using on-screen keyboard inputs, speech, and even pen for various languages. It would be better if you launch the program once by going to the C:/Windows/system32 folder. Doing so will ensure that whatever API is needed for the keyboard typing to work properly again. You also have to make sure that its startup status is not disabled. In addition, you can also try the following steps, alternatively.

• Open the Task Scheduler.
• Then go to Microsoft > Windows > TextServicesFramework.
• And on the MsCtfMonitor, right-click and enable the task.
• Now restart your computer.

This will ensure that all the text boxes will start to work again. And if the task MsCtfMonitor is missing from the list of tasks, you can import it with the XML file from basics.net. Then download and create a task to run it each time you log in to your PC.

Option 2 – Use the Windows Store Apps Troubleshooter

You might also try running the Windows Store Apps Troubleshooter as it can help in resolving issues with the Windows Store apps. This built-in tool can resolve most of the app-related problems. To use it, go to Settings > Update & Security > Troubleshooting > Windows Store Apps and from there, click the start the troubleshooter button. The Windows Store Apps Troubleshooter will scan the computer for any issues with the Windows store apps and will automatically fix them if it finds any.

Option 3 – Re-register all the Windows 10 UWP apps using PowerShell

• First, make sure to close all the running applications on your computer.
• Next, in the Start search, type in PowerShell and right click on the result, and select the “Run as administrator” option.
• After that, type the following commands to re-register the Windows 10 apps. Make sure to hit Enter on each line:
  • reg delete "HKCUSoftwareMicrosoftWindows NTCurrentVersionTileDataModelMigrationTileStore" /va /f
  • get-appxpackage -packageType bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmetadataappxbundlemanifest.xml")}
  • $bundlefamilies = (get-appxpackage -packagetype Bundle).packagefamilyname
  • get-appxpackage -packagetype main |? {-not ($bundlefamilies -contains $_.packagefamilyname)} |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + "appxmanifest.xml")}

Option 4 – Try to run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the problem.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run the System File Checker Scan

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. To run the SFC command, follow the steps given 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.

• Restart your PC.

FLoC is Google’s alternative to third-party cookies and is based on machine learning. This will allow the browser, any browser, to anonymously study how users are browsing and then group them into ‘cohorts’. Following this, you will be served ads based on your cohort and not on your individual data. So, you are still going to be targeted with ads but in a more anonymous manner. Google claims that this will improve user privacy since this “federated learning” happens on the user’s device and artificial intelligence-based learning involves sharing lesser users than what happens with third-party cookies. If something like this gets widely adopted by ad companies and services, it should “protect users” from tracking methods that are more intrusive than third-party cookies, like browser fingerprinting.

Who is against it?

Privacy-focused browsers DuckDuckGo, Brave, and Vivaldi have all warned users against FLoC and have said that they are going to block it on their end. Brave says that Google FLoC has a design that does not respect the customer’s privacy and consent. It has been designed to provide browsing behavior and interest data with any website that users may interact with, and this process does not involve fully informed consent. Vivaldi, another popular Chromium-based web browser, has also made its stance clear regarding the status of FLoC. The company said in a Reddit thread that the FLoC experiment does not work in Vivaldi. It happens because for FLoC to work, some features need to be enabled under the hood, but Vivaldi does not provide those options. The company also added that it plans to stop the entire FLoC component from being a part of the browser, regardless of how Google may implement it. Considering that Brave and Vivaldi have been privacy-focused browsers since their beginnings, the decision to stay away from FLoC is not surprising.

What is Error Code 0xC004C003?

Error code 0xC004C003 has to do with activating Windows 10 after a clean install. This problem has been a frequent nuisance to users trying to update from Windows 7 or 8.1 following the invite path they got from Microsoft.

Solution

Error Causes

There are several problems that may have caused error code 0xC004C003. The most common of them are:

• The product key entered was invalid, and cannot be used to activate the new OS.
• The user followed the proper installation procedure, but the Windows update servers were too busy to handle the activation at that moment.
• The free upgrade invitation was followed but after the reinstallation, the copy of Windows 10 was still not activated.
• The user tried to perform a full clean install of Windows 10 instead of upgrading from Windows to Windows 10

Further Information and Manual Repair

A lot of solving error code 0xC004C003 has to do with the method in which the user has tried to update the system. If one decided to try and update the program before being invited to do so by the update manager, he must wait. Unfortunately, if one chooses to do it on his own and download a clean install, he was never given a product code to authenticate the process. There are two options to address error code 0xC004C003 — either restore to the previous Windows Operating System or call Microsoft (or visit their Website) and purchase a product key. The Windows update servers are very busy. There are lots of Microsoft users around the world, and the servers are doing their best to get to each and every one of the users as fast as possible, but they can only move at a certain speed. Your best bet is to sit back and wait a while. But what if you were invited, and properly downloaded Windows 10, then decided to do a clean install? It is advised that one do not try to enter Windows 7 or 8.1 serial code as this will not work. However, unlike the problem above, these users will NOT need to purchase a product key. According to Microsoft Support Staff, the installation servers are also very jammed because of the high numbers of installations going on right now. No matter what posts you may read, the key IS genuine, and it is NOT blocked, broken, or invalid. To check if Windows has been properly activated, open the Command Window. Make sure you are logged into an administrator profile; otherwise this check will not work. Type in “slmgr.vbs/ato” and click Enter and then wait. While waiting, the command will check on the status of the activation. Windows Script Host will open and show whether or not it is activated. A lot of users have reported that the activation did not work for the first few times. However they later reported after some more attempts, no issue was found in the way the operating system updated and that the activation process went smoothly. This is most likely due to the overload on the Windows Update servers, so bear with Microsoft. Users have reported that when trying to correct error code 0xC004C003, they have followed the upgrade path and then been told by Microsoft that the key was invalid and they had to purchase a new one. If the upgrade path provided by Windows 7 and Windows 8.1 is correctly followed then there is nothing to worry about Just wait a while and try it again. If there are prolonged issues, speak with a technician by visiting the Microsoft website and contacting the help center by calling the number provided. Give them all relevant information and they will be sure to help accordingly. The best solution to fix error code 0xC004C003 is to wait. In essence, the user will be waiting to reenter the same product key. According to Microsoft, and many user posts found online, it is recommended to wait a while and then try to activate again. This seemed to be an answer to most users' problems, and seem to work just fine. If the problem persists, take it to a windows repair technician to have it sorted out. If that does not work, use a powerful automated tool to fix the problem.

If you notice that your tabs in your Firefox browser keep on crashing recently, then there might be something wrong with your browser. Every time any of your tabs crashes, you might encounter an error message saying, “Gah, Your tab just crashed”. If you encounter this kind of error message then it is most likely that your Firefox Profile is having some issues with the existing installation of Firefox. The “Gah, Your tab just crashed” error rarely happens but when it does, it can get quite annoying as you won’t get to browse the internet peacefully. So to fix it, here are some suggestions you could check out.

Option 1 – Try disabling multi-process tabs in Firefox

Since Mozilla has one process for Firefox itself, while one process handles all the tabs, you have the option to disable these multi-process tabs in Firefox. To do that, follow these steps:

• In the address bar of Firefox, type “about: config” and hit Enter.
• Next, look for the following configurations and set them to false.
  • tabs.remote.autostart = false
  • tabs.remote.autostart.2 = false
• After that, double-click on the toggle switch between true and false.

Option 2 – Try checking your Add-ons

In this option, you need to start Firefox in Safe Mode and then check if the problem is fixed. If it is, you may have to check your Firefox add-ons as well as extensions as one of them might be the one that's causing the “Gah, Your tab just crashed” error.

Option 3 – Downgrade the Firefox version you’re using

It could be that the current version of Firefox you’re using has some issues so you might have to downgrade it, especially if you are already using the latest version. To downgrade your Firefox browser, go to the directory of the other versions and languages and select an older version that worked for you. After that, you have to disable automatic Firefox updates.

• First, click the menu button and select Preferences.
• Next, go to the Firefox Updates section under the General panel.
• Then select the radio button labeled “Check for updates but let you choose to install them”. This will ensure that you will not have the same issue with the new update.

Note that this is only a temporary fix since updating your programs, including browsers.

Option 4 – Try sending Crash Reports

You might want to send crash reports to Mozilla. This way, Mozilla might come up with some fix to resolve the problem. All you have to do is type “about: crashes” in the address bar. This will list all the crash reports. Now send it to Mozilla using the built-in interface. Although this won’t instantly fix the problem, a lot of user finds it useful. And besides, the issue will get fixed in future releases or with minor updates.

As of the time of writing this article you no longer need or are required to have a password if you plan to log in to your Microsoft account. Microsoft explored various options for account security and came to the conclusion that passwords are obsolete. Microsoft is letting you access your account through the Microsoft Authenticator app, Windows Hello, a security key, SMS verification, or email verification code. All of these methods are way better in terms of security than passwords.

How to turn these features on?

To get rid of your Microsoft password, the process is simple. You simply need to go to your Microsoft account, click “advanced security options,” then “enable passwordless accounts” under the Additional security section.

Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:

1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.

If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.

1. Use Task Manager to find suspicious entries.

   Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.

2. Use the command prompt to monitor your network.

   In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.

3. Use keystroke encryption.

   Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish

Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.

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.

There is a built-in tool in Windows 10 the Disk Cleanup Utility which can help you restore hard disk space by removing temporary files, Thumbnails, old Windows files, Windows Upgrade logs, Delivery optimization files, and many more. However, from time to time, this built-in tool also experiences some issues. One of these issues is when it gets stuck on Windows Update Cleanup. Read on to find out what you can do in such a case. When the Disk Cleanup Utility is stuck on the Windows Update Cleanup, the process could be slow and take a long time to complete when purging the files. If this happens, click on Cancel to close the dialog box. After that, try running the Disk Cleanup Tool again as administrator and check if the files that you want to clean is still there or not. If it isn’t there, then this means that the cleanup has been done, otherwise, you need to refer to the options given below.

Option 1 – Try to manually delete the contents in the SoftwareDistribution folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer and then try to run Windows Update once more.

Option 2 – Try to manually delete the contents of the Windows.old folder

The Windows.old folder is the one that holds the older version of Windows when you upgrade. It comes really useful when you want to revert to the previous version of Windows 10. Thus, you can delete the Windows.old files in case the cleanup tool is stuck.

Option 3 – Try running Disk Cleanup in a Clean Boot State or Safe Mode

Another thing you can try is to restart your computer in a Clean Boot State or Safe Mode. Chances are, there are some programs that are preventing the Disk Cleanup Utility tool to run properly. After you restart your computer in a Clean Boot State or Safe Mode, try to run the Disk Cleanup tool again and then see if it now works or not.
