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.

Scammers have decided to target Windows’s 10 App installer process in order to infect your computer and steal your data. As in most usual online scams, everything starts with a strange email containing threats and other poorly written and composed speech. At the end of the given email, there would be a link claiming that you, of course, need to read it and follow instructions about the threat, if you click the link it will open a web page where you will have an innocent-looking PDF file with more information about the threat itself. If you click on a seemingly innocent PDF file it will summon Windows 10's AppInstaller.exe tool, kickstarting a download-and-run process that'll put you in a bad place very quickly. From there, you'll have to deal with the dangers of malware BazarBackdoor, including data and credential theft. This kind of scam is nothing new but the interesting thing here is that it uses App installer and by clicking on a link you are opening and giving permission for a malicious crook to use it. So, stay safe and do not click on any links from unknown emails no matter what.

There are times when the WMI Repository gets corrupted which results in the Provider Load Failure. To resolve this issue, you need to repair or rebuild the WMI Repository in your Windows 10 computer. In this post, you will be guided on how exactly you can do that. In case you don’t know, the WMI which stands for Windows Management Instrumentation is a set of specifications from Microsoft to consolidate the management of devices and applications in a network. The WMI is a database that stores meta-information and definitions for WMI classes. Using only these, the conditions of the systems can be known. You can find the WMI Repository in %windir%System32WbemRepository. It provides end-users with the status of the local or remote computer system. Keep in mind that you must not use this on the Server 2012 Cluster machine. Although there are command-line tools that can fix or restore the Windows Management Instrumentation repository. However, Microsoft suggests that it’s better if you verify if there is corruption. Here are a list of errors as well as permission issues you might encounter:

• Unable to connect to root default or rootcimv2 namespaces. It fails with the error code “0x80041002” pointing to “WBEM_E_NOT_FOUND.”
• 0x80041010 WBEM_E_INVALID_CLASS
• When you open Computer Management and Right Click on Computer Management (Local) and select Properties, you get the following error: “ WMI: Not Found” or it hangs trying to connect
• Trying to use wbemtest , and it hangs
• Schemas/Objects missing
• Strange connection/operation errors (0x8007054e)

To verify if there is corruption, you can try running the following command in an elevated Command Prompt:

winmgmt /verifyrepository

 After you enter the command, if there is a response saying, “repository is not consistent”, then the repository has an issue. If not, then something else is causing the problem. Since you are certain that corruption exists in the WMI repository, then here are some suggestions you need to check out to repair or rebuild the WMI repository.

Option 1 – Try to reset WMI Repository

• Type “command prompt” in the Start Search and right-click on Command Prompt from the search results and then select “Run as administrator”.
• After opening Command Prompt with admin privileges, type and enter this command: winmmgmt /salvagerepository

The command you entered is used when the winmmgmt command performs a consistency check. So if an inconsistency is detected, it will rebuild the repository.

• Next, execute this command to see if the WMI repository now comes back as consistent: winmgmt /verifyrepository

This command will perform a consistency check on the WMI repository.

• If it states that the WMI repository is not consistent, then you need to type and enter this command: winmgmt /resetrepository

This command is used to reset the repository to its initial state when the operating system was first installed.

Option 2 – Try to force recover the WMI Repository

The WMI Repository comes with a built-in self-recovery process so when the WMI service restarts or detects any corruption, it will automatically trigger the self-recovery procedure. This can happen in two ways:

• AutoRestore: This will use the backup images if the Volume Shadow copy or VSS backup is turned on.
• AutoRecovery: The rebuilding process will generate fresh images of the WMI repository based on the registered MOFs. The MOFs are available in the registry located at HKLMSoftwareMicrosoftWBEMCIMOM: Autorecover MOFs

Note: Autorecover MOFs is a key so double click on it to check its value. On the other hand, if the self-recovery procedure does not work, you can try to use the force-recovery process instead. How? Refer to these steps:

• First, you need to check the reg key value is empty or not under this registry path: HKLMSoftwareMicrosoftWBEMCIMOMAutorecover MOFs
• If the reg key value is empty, you have to copy-paste the reg key value from another computer. Just make sure that it’s from the System which is equivalent to the computer in question.
• Next, type and enter this command: Winmgmt /resetrepository
• After you enter the command, if you get an error that says, “WMI repository reset failed. Error code:0x8007041B. Facility: Win32”, then you have to stop all the Dependency Services on the WMI service by running the following commands:
  • net stop winmgmt /y
  • Winmgmt /resetrepository

This should fix the problem.

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.
