BSOD or Blue Screen of Death errors are one of the toughest issues you can encounter in Windows 10 as well as the hardest ones to resolve as they simply shut the system down or restart it abruptly and claims that it isn’t possible to boot Windows again. One of the difficult BSOD errors is the Machine Check Exception BSOD error. The reason why it is hard to fix is that in most cases, it occurs soon after Windows loads which gives users little to no time in resolving it. To make things worse, the system also freezes right before it displays the blue screen error and shuts the system down. Usually, the Machine Check Exception Stop error occurs due to the failure or overstressing of the hardware components. And in the case of almost all Blue Screen of Death errors, the issue usually has something to do with the drivers. So if you frequently see this BSOD error from time to time, now’s the time to act on it by following the solutions given in this post.

Option 1 – Update the Device drivers

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. Look for the device driver you and then select either “Update driver” or “Uninstall device”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
• Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 2 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that can be found on 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.
• From there, 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 3 – Try running the System File Checker

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 with good system files that might be causing the Machine Check Exception BSOD error. 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 4 – Run the Startup Repair

In the Blue Screen where the Machine Check Exception error is displayed, tap the F8 key to go to the Startup Settings where you can find Startup Repair and then run it. Note that this is a must-try option especially if you are unable to start your computer and if you can use your computer for a few moments.

Option 5 – Run the DISM tool

There are cases when the Machine Check Exception error is caused by the Windows System Image so you need to repair it using the DISM or Deployment Imaging and Servicing Management tool. The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: Dism /Online /CheckHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 6 – Try resetting the BIOS

If you have made some modifications in the BIOS that might have caused this error, you have to revert those changes to resolve the issue. On the other hand, if you have made a couple of changes and you do not remember which is which, you might have to reset the BIOS.

Option 7 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

For a while now, Microsoft has been working hard to add various built-in troubleshooters in Windows 10. In fact, there is a troubleshooter for almost every standard or common error in Windows 10. And now with the newly released Windows 10 v1903, Microsoft has added the Recommended Troubleshooting which allows Windows 10 to automatically fix a lot of critical issues on your computer, and in this post, you will be guided on how you can turn on or off the Recommended Troubleshooting in Windows 10. The Microsoft Diagnostic & Feedback data only provides two settings – Basic and Full. So if you want to turn off the Recommended Troubleshooting for some reason, the only way to do so is to stop it from collecting complete data from your PC. And to turn it on or off, you can choose to switch between them. To do that, navigate to Settings > Privacy > Diagnostics & feedback and from there, select Basic under the Diagnostic Data section. After that, go back to Settings and go to Update & security > Troubleshoot. Once you’re there, you should see a warning message saying, “Share Full Diagnostic data to get additional troubleshooting recommendations”. Based on the message, Microsoft will only offer the recommended troubleshooting based on the Full Diagnostic data which it collects from your computer. On the other hand, if you know how to navigate and use the Windows Registry, then you can enable or disable the Recommended Troubleshooting via Registry Editor but before you proceed, make sure that you create a System Restore point. Once that’s covered, follow these steps:

• Tap the Win + R keys to open the Run dialog box and type “regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoft
• From there, look for the key named “WindowsMigration”. If you can’t find it, just right-click on the left pane and create a new key and then name it “WindowsMigration”.
• After that, create a DWORD “UserPreference” and double click on it to set its value to “0” if you want to turn it off or “1” if you want to turn it on.
• Exit the Registry Editor and restart your computer to apply the changes made.

Note: The Recommended Troubleshooting functionality can look into the error logs sent back to the Microsoft team and use an algorithm to set up a solution for you and they’re nothing but Diagnostics and Feedback data that Windows collects and sends back to Microsoft. Moreover, the recommendations are only visible if you are connected to the internet, else it will show the same message.

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.

Have you ever deleted a file by mistake? Do not feel bad, we all have, but what if you deleted the file by mistake and then you went to Recycle bin to restore it only to find out that the bin is empty?
