0x3D55: Family App information is corrupted

One of the important processes in the Windows operating system is the Setting Synchronization or SettingSyncHost.exe. This process is the one responsible for synchronizing the settings of your computer with other devices. It is the one that replicates settings like OneDrive, Internet Explorer, wallpapers, and so on, to other systems. However, it has been known to cause high CPU usage in Windows 10 and there are times when it causes the system to freeze or system lags. So if you notice that the SettingSyncHost.exe process is causing high CPU usage in your computer, worry not for this post will guide you in fixing them. You have to be cautious when you notice high CPU usages caused by system processes since cybercriminals mostly set the names of viruses in a way that the system or the user won’t be able to identify them. Cyber crooks could name the virus and malware the same as one of the system processes like SettingSyncHost.exe to make it seem like it’s a legitimate process. Thus, you need to keep in mind that original system processes like the SettingSyncHost.exe file are located in the System32 folder. The original SettingSyncHost.exe file is located in the System32 folder. To check for the same, right-click on the troublesome process in the Task Manager and select Open file location. If the place is any other than the System32 folder, run a full system anti-virus scan on the system. The SettingSyncHost.exe causes high CPU usage when it gets stuck in the sync process and is not able to come out of the loop. To fix this problem, you need to follow the solutions offered below but before you proceed, make sure that you create a System Restore point first.

Option 1 – Apply some registry tweak

The first thing you can do is to apply some tweaks to the Windows Registry. To get started, follow these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERSoftwareMicrosoftInputPersonalizationTrainedDataStore

• After that, check the box next to “Allow” for Full Permission for every user group.
• Now click on the Apply and OK buttons to save the changes made.
• Then restart your computer.

Option 2 – Close the Host process for setting synchronization

If the registry tweak didn’t work, you can try to close the host process for setting synchronization, especially if this process continues to hog resources. You can terminate this process by opening the Task Manager. From there, end the process or task of the host process. On the other hand, you can also turn off the Host process for synchronization by opening Settings > Accounts > Sync settings located in the left pane. After that, turn off the Sync setting.

Option 3 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Performance Troubleshooter:

• Tap the Win + R keys to open the Run dialog box.
• Type “exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Option 4 – Try scanning your computer using Windows Defender

As mentioned, it is possible that the SettingSyncHost.exe could be infected with a virus or malware. To eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.

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.

If an error suddenly pops up that states, “A problem prevented the document from being scanned” when you’re scanning a document in your computer, then you’ve come to the right place as this post will guide you on how exactly you can fix the problem. A lot of users have reported that they receive a two-layer error message when they try to scan their documents – the first screen throws an error message that says, “Error applying Settings to Driver” while the next error message states, “A problem prevented the document from being scanned”. As a result, the scanning won’t be completed which defeats the whole process of buying a printer with a scanner. As you can see the two error messages point to two different situations, while the other one is pointing at the driver, the second one points to the scanning problem. To resolve these issues, there are several suggestions you need to check such as follows:

Option 1 – Run the Printer Troubleshooter

One of the first basic troubleshooting you can perform to resolve the printer issue is running the Printer Troubleshooter. This built-in troubleshooter can detect and automatically fix the problem for you. To use it, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the USB Composite Device option and right-click on it, and select the Update Driver from the options.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try to reset the settings of the Printer or reinstall it

If none of the two options given above worked, you can try to either reset the printer settings or reinstall the printer so that it can go back to its default state. However, if it doesn’t work, you can try to uninstall the printer as well as its related drivers. To do so, follow these steps:

• First, go to Settings > Devices > Printer and Scanners.
• After that, select the printer and select the Remove Device option.
• Once done, restart your computer and check again and see if the error is now fixed.

Option 4 – Try to modify the Registry settings for the Still Image devices

In case you don’t know, Windows has Registry settings for the Still Image devices like Scanners and Printers. And these devices have vendor-specific settings that if ended up getting corrupted or misconfigured then you will most likely encounter errors like “A problem prevented the document from being scanned”. Thus, to fix this error, you can try modifying the Still Image devices registry settings, and to do that, you need to follow the instructions below but before that, make sure that you create a System Restore Point first.

• Once you’ve created a System Restore point, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and then hit Enter to open the Registry Editor.
• Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStillImage
• From there, right-click on the “StillImage” registry key and delete it.
• After that, exit the Registry Editor and restart your computer.
• Once your computer has restarted, Windows will recreate the settings of the Still Image devices back to their default settings.

If you recently upgraded your computer or if you’ve just switched to a new Windows 10 PC, the most common errors you might encounter are the Windows Activation errors. This issue boils down to the Windows Activation server which has either failed to validate or recognize the license tied to the digital account. In this post, you will be guided on how to fix an activation error in an organization with an error code 0x8007007B. It contains this exact error message: “We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.” Various computers are activated via the KMS licensing (Key Management Server) in organizations. Computers that are activated using this process do not get a permanent activation and have to stay connected to the organization instead of for at least 7 months or 180 days. It is common in Pro and Enterprise versions that are deployed in bulk for at least hundreds or thousands of computers. So imagine a user with a personal computer in the office who decided to leave the organization but will still have an activated Windows key. And so to prevent that from happening, organizations use the KMS licensing. Another possible cause of the error is in case some user used an organization key and later on, the PC just got upgraded or downgraded to a version that is not compatible with that copy of Windows. To fix this Windows Activation error, here are some suggestions that might help.

Option 1 – You can try connecting to the organization’s network and activate the computer. But before that, you need to first check if the computer actually belongs to an organization or not.

• Tap the Win + R keys to open the Run dialog box.
• Type “cmd” and hit Enter to open an elevated Command Prompt.
• After that type the vbs /dlv command and hit Enter to execute it.
• Next, check if the Product Key Channel says “GVLK”. If it does, then it means that your computer was activated using volume licensing.

Option 2 – Change Licence Key

If you’ve recently left an organization then it’s best if you buy another copy of Windows 10 and then change the license key. This time, make sure that the license key is for the same version of Windows. However, if it’s different, you need to format your computer.

Option 3 – You can try activating Windows 10 using a mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 4 – If you think that the issue is caused by some hardware changes, you can try using the Activation Troubleshooter.

There are times when users already have the license keys and were able to activate Windows. However, it doesn’t last long and only works for a while and it’s suddenly throwing up an activation error like this one. To use the Windows Activation Troubleshooter, just go to Settings and to Activation and then run the troubleshooter from there. If you've made some modifications to your hardware, you have to click the “I changed hardware on this device recently” option for further suggestions.

Windows 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.

If you are trying to run Windows Upgrade on your Windows 10 computer but suddenly interrupted by the error 0x800F081E – 0x20003, worry not for this post will guide you on how you can fix this Windows Upgrade error. This particular Windows Upgrade error is a Windows status code for CBS_E_NOT_APPLICABLE which indicates that some of the update requirements are missing or the files that are installed are already of a higher version compared to the ones that are still pending. In most cases, this error occurs when you try to upgrade to earlier versions of the Windows 10 N edition to a later version. Here’s the full content of the error message:

“0x800f081E-0x20003, The installation failed in the SECOND_BOOT phase with an error during BOOT operation”

In case you don’t know, Microsoft distributes special “N” editions of Windows in Europe and the “KN” editions in Korea. These editions are the same as the standard editions of Windows except that they do not have the Windows Media Player as well as the multimedia playback features. Thus, when the Windows Upgrade fails with the error code and error message and it doesn’t provide much information as to why the update couldn’t be installed, there is something you can do about it to fix the error. Since Windows uses generic error codes and so if you see the error code 0x800f081e, you have to check the error log first. For more details, follow the instructions laid out below. Step_1: You need to navigate to C:$WINDOWS.~BTSourcesPanther and from there look for the text file named “setuperr.log” and open it with a text viewer/editor program like Notepad. Step_2: After opening the setuperr.log file, you should see content that’s similar to this:

C:WINDOWSSoftwareDistributionDownload80b2677d6e15a2a206625bb25a7124feamd64_Microsoft-Windows-MediaPlayer-Package~~AMD64~~10.0.17134.1.

Error: 0x800F081E[gle=0x000000b7]

Note: From the content above, it is clear that the Windows Upgrade failed due to complete due to the Windows Media Player. It could be that the log file may contain other error messages and other error codes and if you see the error code 0x800f081e from the list, then you need to uninstall the Media Feature Pack. Step_3: You have to uninstall the Media Feature Pack.

• Tap the Win + R keys to launch the Run dialog box and type “optionalfeatures.exe” in the field and hit Enter to open the Windows Features wizard.
• Next, you need to wait until the list of Windows Features populates and then click on the + sign to collapse the folder of the Media Features.
• After that, uncheck the “Windows Media Player” option from the Media Features folder.
• Now click on the Yes and OK buttons to save the changes made and then close the Windows Features dialog box.
• Restart your computer and boot, try to run the Windows Upgrade process again, and check if the error is fixed or not.

Note: If the installation has been successfully completed, you have to go back to the Windows Features and enable the Windows Media Player again. And if you are using the Windows 10 N Edition, then you can just download and install the latest version of the Media Feature Pack for your Windows 10 N edition. On the other hand, running the built-in Windows Update troubleshooter could also help you resolve any Windows Update-related problems, including the error 0x800F081E – 0x20003. 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.

CalendarSpark is a browser extension developed by MindSpark. This extension allows an easy way to print or view calendar templates and make schedulers for a day/week/month/year. This browser extension hijacks your browser home page and search engine, changing them to MyWay.com. While the extension is installed it monitors your browsing activity and collets visited websites, clicked links, and sometimes even personal information, which it later uses to display targeted unwanted ads through your browsing sessions.

While browsing the internet with this extension installed you will see additional sponsored links, ads, and sometimes even pop-up ads on websites that are not supposed to have any of these. Several anti-virus scanners have detected this extension as a Browser Hijacker, and due to its data collecting behavior, it is not recommended to keep it on your computer.

About Browser Hijackers

Browser hijackers (sometimes called hijackware) are a kind of malware that modifies web browser configuration settings without the computer owner’s knowledge or permission. These kinds of hijacks are raising at an alarming rate across the world, and they could be truly nefarious and sometimes harmful too. Browser hijacker malware is created for a number of reasons. These are generally used to force hits to a specific site, manipulating web traffic to generate ad revenue. However, it’s not that harmless. Your online safety is jeopardized and it is also extremely irritating. In a worst-case scenario, your browser could be hijacked to open up your computer system to a host of additional attacks.

Indications of browser hijack

When your browser is hi-jacked, the following could happen: your home page is reset to some unknown webpage; you get redirected to sites you never intended to visit; The default search page of the web browser is changed; unwanted new toolbars are added to your internet browser; you’ll find random pop-ups start showing on a regular basis; your internet browser starts running slowly or exhibits frequent errors; Inability to navigate to certain websites, particularly antivirus as well as other security software sites.

Exactly how browser hijacker finds its way onto your PC

Browser hijackers can enter a PC by some means or other, including via file sharing, downloads, and e-mail as well. They could also be deployed via the installation of an internet browser toolbar, add-on, or extension. A browser hijacker can be installed as a part of freeware, shareware, demoware, and pirated programs. An example of some well-known browser hijacker includes Conduit, Anyprotect, Babylon, DefaultTab, SweetPage, RocketTab, and Delta Search, but the names are regularly changing. Browser hijackers could interrupt the user’s web surfing experience significantly, track the websites visited by users and steal sensitive information, cause problems in connecting to the net, and then finally create stability issues, causing programs and computers to freeze.

Removal

Some kinds of browser hijackers can be quickly removed from the computer by deleting malicious applications or any other recently added freeware. Regrettably, most of the software applications used to hijack an internet browser are intentionally designed to be difficult to remove or detect. Furthermore, manual removals require in-depth system knowledge and therefore can be an extremely difficult job for novice computer users.

What you can do if Virus Stops You From Downloading Antivirus?

Practically all malware is inherently dangerous, but certain types of malware do much more damage to your computer than others. Some malware sits in between your computer and your internet connection and blocks a few or all websites that you would like to check out.
