When you encounter this error, you will see the following error message on your screen:

“There were problems installing some updates, but we’ll try again later. If you keep seeing this and you want to search the web or contact support for information, this may help: 2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776) – Error 0X800F0900”

This kind of Windows Update error is most likely caused by some corrupted files in the system. It is also possible that the Windows Database might have become corrupted as well. So if you are currently experiencing this problem, refer to the options given below and see which one of them works best for you.

Option 1 – Try running the DISM Tool

Running the DISM Tool 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”.

• Open the Command Prompt as admin.
• Then type in this command: 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.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker or SFC scan

The SFC scan or System File Checker is a built-in command utility in Windows that helps in restoring corrupted files as well as missing files that cause several issues in the computer like the Windows Update Error 0x800f0900. It replaces bad and corrupted system files with 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.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Perform a System Restore

You can also try to perform a System Restore as it can also help you fix the Windows Update Error 0x800f0900. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Reset both the SoftwareDistribution and Catroot2 folders

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• 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.

Whatever the cause is, here are some suggestions you need to check out to resolve this Blue Screen error.

Option 1 – Try to rollback, update, or disable the Graphics card drivers

• 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 removing hardware or drivers that you’ve installed recently

If you have recently installed some hardware or drivers, you might want to disable or remove them since external devices are proven to be one of the factors that trigger Blue Screen errors like THREAD_STUCK_IN_DEVICE_DRIVER. All you have to do is physically disconnect any external devices that are connected to your computer and then check if it fixes the BSOD error or not.

Option 3 – Run System File Checker at boot time

• Once you get to the Welcome Screen part, click on Next.
• Afterward, click on the Repair your computer option located on the bottom-left part of the window.
• Then click on Troubleshoot.
• Next, select the Advanced Options and then Command Prompt.
• After opening Command Prompt, type the “sfc /scannow” command and hit Enter to run the System File Checker scan.
• Wait until the process is completed and type “exit” to close Command Prompt and then restart your computer to successfully apply the changes made.

Option 4 – Try to run the Blue Screen Troubleshooter

As you know, the Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like the THREAD_STUCK_IN_DEVICE_DRIVER error. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• After that, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Try to manually check the Graphics Card hardware

You might also want to check the physical status of your Graphics card and you can do this by disconnecting the Graphics card or any other external device connected to your computer. Once you’ve removed the external device, check it for any damages. If there’s none, connect it back to your computer and check if the THREAD_STUCK_IN_DEVICE_DRIVER Blue Screen error is fixed or not.

• Now click on the entries of every faulty driver and click on the Uninstall option.
• Once you’ve uninstalled them, restart your computer to allow your computer to reinstall the faulty drivers you’ve just removed.

What is Babylon?

Babylon is a self-published computer dictionary and translation program. Babylon is a tool used for translation and conversion of currencies, measurements, and time, and for obtaining other contextual information. The program also uses a text-to-speech agent so users hear the proper pronunciation of words and text. Babylon’s translation software adds the Babylon toolbar identified as a browser hijacker. This toolbar may modify the homepage of the browser. It adds a Scheduled Task, Startup file, and Registry Keys that allow it to run at any time. A Windows Firewall exception is also added for the software, allowing it to connect to the internet without content.

About Browser Hijackers

Browser hijacking is actually a type of unwanted software program, commonly a browser add-on or extension, which causes modifications in browser settings. Browser hijackers will do a number of things on your computer. Often, hijackers will force hits to internet sites of their choice either to increase targeted traffic generating higher ad revenue, or to obtain a commission for each and every user visiting there. It could seem harmless, but the majority of these websites aren’t legitimate and can present a significant risk to your online safety. Additionally, hijackers can make the entire infected system fragile – other harmful malware and viruses will take hold of these opportunities to get into your PC effortlessly.

Signs of browser hijacker malware

There are several symptoms of browser hijacking. Here are a few of them: the home page of your browser is changed all of a sudden; new bookmarks pointing to porn websites are added to your favorite pages; the default browser settings have been modified and/or your default search engine is altered; unsolicited new toolbars are added to your internet browser; you notice a lot of pop-ups on your computer screen; your web browser gets sluggish, buggy, crashes frequently; you cannot go to certain sites such as homepages of anti-malware software.

How it infects your computer

Browser hijackers may use drive-by downloads or file-sharing networks or perhaps an email attachment in order to reach a targeted computer system. They may also originate from any BHO, browser extension, toolbar, add-on, or plug-in with malicious intent. Sometimes you might have accidentally accepted a browser hijacker as part of a software bundle (usually freeware or shareware). Examples of well-known browser hijackers include Fireball, GoSave, Ask Toolbar, CoolWebSearch, Babylon Toolbar, and RocketTab. The existence of any browser hijacker on your system will considerably diminish the browsing experience, monitor your online activities that lead to troublesome privacy issues, produce system stability issues and finally cause your PC to slow down or to a nearly unusable state.

Browser hijacker removal tips

Some hijackers can be easily removed by deleting the free software they were included with or by eliminating any add-ons you’ve recently added to your computer system. Sadly, most of the software packages used to hijack a web browser are intentionally designed to be hard to eliminate or detect. And there’s no denying the fact that manual fixes and removal can be quite a difficult task for an inexperienced PC user. Besides, there are numerous risks associated with fiddling around with the pc registry files. Anti-malware application is extremely efficient when it comes to picking up and eliminating browser hijackers that regular anti-virus program has overlooked. To get rid of any kind of browser hijacker from your PC, you could download this top-notch malware removal tool – Safebytes Anti-Malware.

Kernel_Data_Inpage_Error - What is it?

Kernel_Data_Inpage_Error is a BSOD (blue screen of death) error. Also, know as a 0x0000007A Stop error. This bug check indicates that the requested page of kernel data from the paging file failed to be read into memory. In simple words, this means that Windows has trouble reading from the memory.

The Kernel_Data_Inpage_Error turns your computer screen all blue, stops the program being executed, and sometimes even leads to abrupt system shut down.

Error Causes

Kernel_Data_Inpage_Error may occur due to numerous reasons. The exact cause of this error can easily be found by going through the code displayed in the parameter of 0x00000007A. Let’s take a look at Kernel_Data_Inpage_Error parameter codes and the underlying causes of its occurrence:

• 0xC0000009A- This parameter code triggers missing nonpaged pool resources
• 0xC0000009C- This represents the installed hard disk drive has bad sectors.
• 0xC0000000E- This indicates a hardware failure or an incorrect drive configuration

Further Information and Manual Repair

No matter what the cause for Kernel_Data_Inpage_Error may be, it is advisable to fix it immediately as blue screen of death error codes are considered to be critical PC errors that can cause serious damages and even result in valuable data loss. Here are a couple of ways to repair this issue on your system:

1. Call the ‘Chkdsk’ (check disk) command on your system.

Windows XP, Vista, and 7 users can call this command, by pressing Windows Key +F and type in ‘chkdsk’ and run. However, you can’t run it while actively using Windows but you can always schedule it to start automatically the next time your computer turns on. Wrap up what you need and then reboot. Chkdsk disk checking process can take a long time, especially on large and slow hard drives. To run this command on Windows 8, open Windows search by pressing Windows Key+ F and then type ‘cmd’. Then right-click on the command prompt and choose the option ‘Run as Administrator’. To continue with the disk checking process, here you will be prompted to provide your administrator authentication. Once you insert the administrator authentication, type the command ‘Chkdsk C:/f/r/x” where the letter ‘C’ indicates the drive you want to examine and repair. Run it to scan for Kernel_Data_Inpage_Errors on your system. Chkdsk command will detect and repair errors on the hard drive and then automatically reboot.

Limitations to this Solution:

‘Chkdsk’ is a value-adding inbuilt disk checking tool in PC new Window versions; nonetheless, this command has certain limitations. It is time-consuming. You may have to wait for a long time for it to scan your system. Also when disk check is running, you will have to stop all other activities on your system. Furthermore, Chkdsk does not scan and fix all registry errors and other PC-related errors. So, you can’t be 100% sure that it will resolve all the Kernel_Data_Inpage_Errors on your PC.

Interesting information has come out from Microsoft, Windows 11 dark theme will include a different sound theme from its standard light one. When in dark mode on Windows 11, the system sounds generally become softer, and they echo a bit, creating a more soothing experience that matches the overall look and feel of the dark mode. Flipping back to light mode brings the system sounds back to their normal level. However, even though the light model has slightly louder sounds than the dark mode, Microsoft has taken great care to make sure the audio is more soothing, according to a report from CNBC. The designers of Windows 11 took inspiration from an approach called calm technology. Microsoft’s Christian Koehn and Diego Baca wrote about calm technology in a post on Medium. In it, they said, “Windows 11 facilitates this through foundational experiences that feel familiar, soften formerly intimidating UI, and increase emotional connection.” According to a Microsoft spokesperson in a statement to CNBC, “The new sounds have a much rounder wavelength, making them softer so that they can still alert/notify you, but without being overwhelming.”

Why combining hard drives with storage spaces? Ok, I will admit it, I am a modern digital hamster when it comes to digital goods. I like to collect stuff and more than anything else I like to have all of that at the tip of my fingers. And how digital goods grow in size themselves (movies on Blu-ray are like 50GB each) and the collection grows in size single hard drive is starting to be completely obsolete when it comes to storage. Sometimes we will need large storage for these kinds of personal collections, sometimes we will need it for work reasons. Whatever your reason might be Windows 10 is offering us a solution via Storage spaces. Storage spaces is an integral part of Windows and it is meant as a tool to provide you with a RAID environment without a RAID controller. Of course, combining multiple hard drives via storage paces instead of RAID will not be so fast or stable but for home use of storing a large quantity of data is perfectly enough. With Storage Spaces you will also have an option to reduce some space for increased security of data loss if by any chance one of your HDD fails.

How to Create a Storage Space

To create storage space in Windows, press ⊞ WINDOWS + R to open the run dialog. In the run box type in Control Panel and press ENTER In Control Panel find Storage Spaces and left-click on it. Once storage spaces open, left-click on Create a new pool and storage space Once you click on create new, you will be greeted with a list of hard drives you can use for this operation. Please note that all hard drives you choose will be completely erased and formatted and then assign a single drive letter. Click on Create pool. You will find yourself in new storage options where you can assign a drive letter, give storage space a name, etc.

Storage spaces types

One thing I would like to focus on here is resiliency type, when you expand the resiliency type drop-down menu you will see 4 options inside. Simple, Two-way mirror, Three-way mirrors, and Parity. Simple: If you choose Simple as an option, you will have maximum hard drive space but no resiliency at all, meaning that if by any chance any of your hard drives malfunction, you are losing your data from that drive completely. Two-way mirror: This option will save your data if one of your drives fails but you need at least 2 drives and storage space will be limited since some of it will be a safe backup option for the case of a drive failure. However if one of your drives fails, you can replace it in a second and keep on working as nothing happened. Three-way mirror: This option similar to the previous one will offer you safe data-keeping from a hard drive failure. this option will save your data even if 2 hard drives malfunction but it will require having 5 of them connected in order to be able to choose this option. Parity: Maybe the most popular option among people who want to have 2 or 3 drives merged but do not want to lose too much space of the two-way mirror option. It offers some protection and it does not take so much space as two-way does, let us say it is a kind of win-win situation.

Conclusion

I personally go for simple and have an important backup on optical drives but only for reason I could use more space, know that this way is requiring from me to always have a backup in optical media and that I will need to restore all of it back if even one HDD fails which could take time. But if this way is ok with you, go for it, you will have more space to use.

Same as in previous Windows versions, Windows 11 will also use certain applications as default ones for opening certain file types and file extensions. And yes, same as in previous versions it will come preconfigured for certain file types and associated applications like for example photos for pictures. Of course, users usually have their own favorite applications for certain file types and much more prefer to open them inside the application of their choice instead of the default one. We can change the default application like in previous Windows versions but this time there are two ways and overall more control of this process. Windows 11 has settings for choosing default file type applications and default file extension applications giving you more control of this process.

The opening setting for apps

Whatever you wish to change default application or default extension application you will need to open settings for default application. Follow steps to quickly go into it.

1. Press ⊞ WINDOWS + I to open settings
2. Select Apps on left
3. On the right part select Default Apps

Now you are in settings for choosing default applications

Choosing default application by file type extension

This is considering by Microsoft as a typical way to set default applications inside Windows 11. Once you are inside the settings app there is a box labeled Enter a file type or link type. Inside the search box, type in file extension that you wish to associate the application with like .JPG, .TXT, or other. If the file extension is not associated with any application you will be presented with a Choose a Default button, if however, the file extension is already associated with the app, you will need to click on the app box itself. In any case, a pop-up will appear and ask How do you want to open YOUR FILE EXTENSION files from now on? Choose Application from the list of presented ones and click on OK.

Choosing default file type

Another method is to select the default application by file type selecting application for it. In the settings screen, under the search box, you will have a list of installed applications. Choose the application that you would like to associate a file type with and click on it. On the next details screen scroll down and select the file type that you want to associate with the selected application and click on OK.

Other/third method

There is also the third method for choosing the default application for file type but it includes some surfing on your hard drive and it can be more time-consuming for first-time settings. But it is fairly quick when you need to only use it once on some new file type (for example you have a new application installed and want to switch just one file type extension to that application). Locate the file that you want to associate with the application and right-click on it. Select Open With from the menu and then Choose Another App. Pop up will appear, select the application that you would like to use, and check the box beside Always use this app to open CHOOSEN EXTENSION files followed by clicking on the OK button.
